What Do Cigars Do to Your Lungs

Breathing is something most people never think about until it becomes hard. You breathe in and out about twenty thousand times a day without trying, and the lungs do their work quietly in the background. Cigar smoke changes that quiet work. A cigar produces a thick, heavy smoke, and a single cigar session can last an hour or more. Even a person who says they do not inhale still breathes in a great deal of that smoke, because it fills the air around them and drifts into the nose and mouth with every breath. The lungs are built to handle clean air, not tobacco smoke, and the smoke irritates them from the first puff to the last.

Many cigar smokers believe their lungs are safe because they do not draw the smoke deep into the chest the way a cigarette smoker does. That belief is understandable, but it is wrong. The smoke still reaches the mouth, the throat, and the upper airways, and a good part of it is breathed into the lungs, especially when a person talks, laughs, or takes a deeper breath while smoking. The chemicals in cigar smoke are the same kind found in cigarette smoke, and they do the same kind of damage: they inflame the airways, they damage the tiny cleaning hairs inside them, and over time they reduce how much air the lungs can hold and move. The damage builds slowly, and the first signs are easy to blame on a cold, on the weather, or on getting older.

This article explains, in plain words, what cigars do to the lungs: how the smoke irritates the airways, why coughing and breathlessness appear, how the lungs lose capacity over time, why chest infections become more common, what the long-term risks look like, and what improves after a person stops. It is general information, not individual medical advice. If you are worried about your breathing, or you smoke cigars regularly, a qualified health professional is the right person to talk to.

What Cigar Smoke Does the Moment You Breathe It In

When cigar smoke enters the mouth and throat, it meets tissue that is warm, wet, and sensitive. The smoke is hot, and it carries thousands of chemicals, including tar, nicotine, carbon monoxide, and dozens of substances known to irritate living tissue. The lining of the airways reacts at once. It swells slightly, it produces more mucus to try to trap the irritants, and the muscles around the airways tighten. That is why a first-time cigar smoker often coughs, feels a burning in the throat, or finds their voice goes hoarse. The body is trying to protect itself, and the cough is part of that protection.

For a regular smoker, the cough becomes familiar, and the throat soreness becomes part of the routine. But familiarity does not mean the irritation has stopped. Each cigar brings a fresh dose of hot smoke and chemicals, and the airways never get a long enough break to fully settle. The mucus that the airways produce to trap smoke is meant to be cleared away by tiny hairs called cilia, which sweep it upward and out of the lungs. Cigar smoke damages those hairs, so the mucus stays where it is, thick and sticky, and the lungs become a place where germs can settle and grow. That is one reason cigar smokers catch chest infections more often, and take longer to recover from them.

The smoke also reaches the smallest airways deep in the lungs, the tiny tubes that carry air to the air sacs where oxygen passes into the blood. Those small tubes are delicate, and repeated exposure to smoke makes them narrower and stiffer. When they narrow, air moves more slowly in and out, and the person has to work harder to breathe. At first the extra effort is only noticeable during exercise, when the body needs more air quickly. Later, even walking on flat ground or climbing a few stairs can feel hard. The change is gradual, which is why it is so often missed until the lungs have already lost a good deal of their capacity.

Coughing, Hoarseness and the Morning Cough

A cough that will not go away is one of the commonest signs that cigar smoke is harming the lungs. It often starts as a cough in the morning, when the lungs try to clear the mucus that has built up overnight. The person coughs for a few minutes after waking, brings up some mucus, and then feels better for the rest of the day. That morning cough is easy to dismiss as normal, especially if friends who smoke have the same cough. But a healthy pair of lungs does not need to cough every morning. A daily cough is a sign that the airways are irritated and are struggling to clear themselves.

Hoarseness is another early sign. The smoke passes over the vocal cords in the throat, and the heat and chemicals inflame them. The voice becomes rough, lower, or tired by the end of the day. A person may find they cannot speak as loudly as they used to, or that singing, shouting, or talking for a long time leaves the throat sore. The change is slow, so the person adjusts to the new voice without noticing how much it has changed. Family members often notice it first, because they hear the voice every day and remember how it used to sound.

Over time, the cough can become a feature of the whole day, not just the morning. A laugh can set it off. Cold air can set it off. A dusty room can set it off. The airways have become sensitive, and they react to things that would never have bothered them before. That sensitivity is a sign of chronic irritation, and it does not go away while the smoke keeps coming. The cough is not just an annoyance. It is the lungs asking for clean air, and it is worth listening to, because the longer the irritation continues, the harder it becomes for the lungs to recover.

How the Airways Narrow and Breathing Gets Harder

The airways are tubes that branch again and again, getting smaller as they go deeper into the lungs, like the branches of a tree. Cigar smoke damages them at every level. In the larger airways, the lining swells and produces extra mucus. In the smaller airways, the walls thicken and the tubes narrow. The result is the same in both cases: air has a harder time getting in and out, and the person has to use more effort to breathe. Health professionals call this airflow limitation, and it is the central problem in the long-term lung damage caused by tobacco smoke.

Breathlessness, or shortness of breath, is the symptom that most people notice first. It starts with effort: climbing stairs, walking uphill, carrying something heavy. The person feels they cannot get enough air, and they have to stop and rest. At first they recover quickly, and they blame being unfit or out of practice. But as the airways narrow further, the breathlessness comes with less effort, and the recovery takes longer. A walk to the shops, a short flight of stairs, or playing with a child can leave the person breathing hard for several minutes. That is not a normal part of getting older. It is a sign that the lungs are losing their ability to move air freely.

Wheezing is another sign. It is a whistling sound when breathing out, caused by air squeezing through narrowed airways. Some people wheeze only after smoking, or only when they have a cold. Others wheeze most days, especially in the morning or at night. Wheezing means the airways are tight, and it is often worse in cold air or after exercise. A person who wheezes regularly should talk to a health professional, because the narrowing that causes wheezing can be measured, and the measurement shows how much lung capacity has already been lost, even if the person feels they are coping.

Losing Lung Capacity Over Time

Lung capacity is the amount of air the lungs can hold and move. It is highest in a person’s twenties, and it falls slowly with age. Cigar smoking makes it fall much faster. The smoke damages the air sacs, the tiny balloon-like structures where oxygen passes into the blood. In a healthy lung, those sacs are springy and full of surface area. Smoke breaks down their walls, so they become larger, floppier, and less efficient. Fewer working air sacs means less oxygen getting into the blood, and that means less energy for the whole body. This damage is called emphysema, and it is one of the most serious long-term effects of tobacco smoke on the lungs.

The loss of capacity is slow and silent. A person may lose a third of their lung capacity before they notice a real problem in daily life, because the body is good at adjusting. They walk more slowly, they avoid stairs, they take more breaks, and they call it being sensible. But each adjustment is a small loss of freedom, and the losses add up. A person who could once run for a bus may find they can only walk to it. A person who once worked a physical job may find the work exhausting by midday. The lungs are not healing between cigars, because the smoke keeps coming, and the damage keeps adding up.

The amount of loss depends on how much a person smokes and for how long. A person who smokes a few cigars a week will lose capacity more slowly than a person who smokes several a day, but the direction is the same. There is no safe amount of cigar smoke for the lungs, because even occasional smoke causes irritation and inflammation, and the body needs time without smoke to repair the lining of the airways. A regular smoker never gives the lungs that time. The good news is that stopping slows the loss sharply, and the lungs begin to clear themselves within weeks. The capacity that is already lost may not fully return, but the rate of loss can return close to normal, and that is a real and important gain.

Chest Infections That Keep Coming Back

Cigar smokers catch chest infections more often than non-smokers, and they take longer to get better. The reason is simple: the lungs’ cleaning system is damaged. In a healthy lung, the tiny hairs called cilia sweep mucus and germs upward, and the mucus is coughed out or swallowed. Cigar smoke paralyses those hairs and damages them, so mucus sits in the airways, thick and stagnant. Germs settle in that mucus and grow, and the body’s defences are slower to reach them, because the smoke also weakens the immune cells that guard the lungs.

A cold that would last a few days in a non-smoker can turn into a chest infection that lasts for weeks in a cigar smoker. The cough becomes deeper, the mucus becomes thicker, and the breathlessness gets worse. Bronchitis, an inflammation of the airways, is common in cigar smokers, and it can become chronic, meaning the cough and mucus last for months at a time, year after year. Pneumonia, a more serious infection of the air sacs themselves, is also more common, and it is more dangerous, especially for older people or people who already have lung damage.

The pattern of repeated infections is itself a warning. Each infection causes more inflammation, and that inflammation causes more scarring in the airways, which makes the next infection more likely. It is a loop, and the only way to break it is to remove the smoke that keeps damaging the cleaning system. After stopping, the cilia begin to recover within weeks, and the lungs start to clear mucus properly again. Many former smokers notice that they catch fewer colds, and that the colds they do catch clear up faster. That improvement is one of the earliest and most encouraging signs that the lungs are healing.

The Long-Term Risks: Chronic Lung Disease and Cancer

The most serious long-term risk from cigar smoking is chronic obstructive pulmonary disease, usually shortened to COPD. COPD is a long-term condition in which the airways stay narrowed and the air sacs stay damaged, so breathing is always harder than it should be. People with COPD live with daily breathlessness, a persistent cough, and frequent chest infections. Simple tasks become exhausting, and a bad winter can mean weeks of illness. COPD is not curable, and it gets worse over time if the person keeps smoking. Health guidance is clear that cigar smoking raises the risk of COPD, and the risk rises with the amount smoked and the number of years a person has smoked.

Cigar smoking also raises the risk of lung cancer. The smoke contains chemicals that damage the cells lining the airways, and over years that damage can lead to cells growing out of control. The risk is lower than for a heavy cigarette smoker, because most cigar smokers smoke less often, but it is still much higher than for a person who has never smoked. Cigar smoke also raises the risk of cancers of the mouth, throat, and voice box, because the smoke sits in the mouth and throat for a long time during a cigar session, and those tissues absorb the chemicals directly. A cigar smoker who does not inhale is still exposing the mouth and throat to smoke, and those cancers are a real risk even without deep inhaling.

These risks sound frightening, and they are meant to be taken seriously, but they are not a reason to give up hope. The risk of lung cancer and COPD falls after a person stops smoking, and it keeps falling year by year. The body cannot undo all the damage, but it can stop adding to it, and the lungs can recover a good deal of their function. A person who stops at any age gains years of easier breathing compared with a person who keeps smoking, and that is true even for someone who has smoked for decades. The best time to stop was years ago. The second-best time is now.

Secondhand Cigar Smoke and Other People’s Lungs

A cigar produces far more smoke than a cigarette, and that smoke fills a room quickly. The people nearby breathe it in, and their lungs feel the effects too. Secondhand cigar smoke contains the same irritating chemicals as the smoke the smoker breathes, and it causes the same kind of airway irritation, coughing, and breathlessness in the people who breathe it. Children are the most vulnerable, because their lungs are still growing, they breathe faster than adults, and they cannot choose to leave a smoky room.

Children who grow up in homes where cigars are smoked indoors are more likely to have asthma, chest infections, and ear infections, and they are more likely to miss school because of breathing problems. Their lungs grow more slowly, and they may carry that disadvantage into adult life. For adults, secondhand cigar smoke raises the risk of lung disease and heart disease, and it can make existing breathing problems, such as asthma, much worse. A person with asthma who sits near a cigar smoker may find their chest tightening within minutes, and they may need their inhaler more often for hours afterwards.

Smoking outside helps, but it does not remove the risk completely, because smoke clings to clothes and hair and comes back indoors with the smoker. The only way to fully protect the people around you is to stop smoking cigars, or to keep the smoke well away from them, in open air and away from children. Many cigar smokers are surprised by how much smoke a single cigar makes, because they are used to it and no longer notice it. The people around them notice it, and their lungs notice it too, even if they say nothing.

What Happens to the Lungs After You Stop

The lungs begin to recover surprisingly quickly after a person stops smoking cigars. Within a few days, the carbon monoxide clears from the blood, and the blood can carry oxygen properly again. Within a few weeks, the tiny cleaning hairs in the airways begin to work again, and the lungs start to clear mucus more effectively. Many people notice that their morning cough gets worse for a short time after stopping, because the lungs are finally clearing out the mucus that has been sitting there for months. That temporary worsening is a sign of healing, not a sign that stopping was a mistake, and it usually settles within a few weeks.

Over months, the breathing improves. The airways become less swollen, the mucus becomes thinner, and the breathlessness during effort eases. A person who could only walk slowly may find they can walk at a normal pace again. A person who had to stop halfway up the stairs may find they can reach the top without stopping. The improvement is gradual, and it is not the same for everyone, but it is real, and it is one of the most satisfying parts of stopping. The sense of taste and smell also returns, because the smoke no longer dulls them, and food begins to taste better.

The long-term gains are even more important. The rate at which lung capacity falls slows down to near normal, and the risk of chest infections drops. The risk of lung cancer and COPD falls steadily year by year. The lungs will not return to the state they were in before smoking began, especially after many years of smoking, but they will be far healthier than they would have been if the person had kept smoking. Every year without smoke is a year in which the lungs are not being damaged further, and that is a gift worth giving them, at any age.

Cigars, Colds and the Changing Seasons

The lungs’ struggle with cigar smoke becomes most obvious when the seasons change. In winter, cold air alone can make the airways tighten, and for a cigar smoker, that tightening is worse, because the airways are already swollen and sensitive from smoke. A walk in cold morning air that would be refreshing for a non-smoker can leave a cigar smoker coughing and breathless. The cold air also carries more germs, and the damaged cleaning system in the smoker’s lungs is slower to clear them, so winter colds last longer and more often turn into chest infections.

Spring brings dust and pollen, and those irritants land on airways that are already inflamed. A person who never noticed pollen before may find they sneeze, cough, and feel tight-chested in spring, and they may think they have developed an allergy, when the real change is that their airways have become more sensitive because of the smoke. Summer brings heat and humidity, and the body needs more oxygen when it is hot, but the damaged lungs cannot deliver it as easily, so a hot day feels exhausting. Each season adds its own burden, and the lungs, already working hard because of the smoke, have less room to cope.

The pattern across the year is a useful way to see the damage. A healthy pair of lungs handles the seasons without much trouble. Lungs damaged by cigar smoke struggle in every season, in a different way each time, and the person begins to dread the changes in weather. That dread is a sign worth listening to. If the weather itself has become an enemy, the problem is not the weather. It is the lungs, and the smoke that has made them fragile. Stopping gives the lungs a chance to become less sensitive, and many former smokers notice that the seasons become easier within a year, as the airways calm down and the cleaning system recovers.

My Take:

I will be honest with you. I think the lungs are the part of the body that cigar smokers forget about most, because the damage is so quiet. A heart problem announces itself with chest pain or a racing heartbeat. Lung damage announces itself with a small cough in the morning, a little breathlessness on the stairs, a voice that sounds rougher than it used to. Each of those signs is easy to explain away, and most cigar smokers do explain them away, for years. By the time the breathlessness is impossible to ignore, the lungs have already lost a large part of their capacity, and some of that loss will never come back. That quiet, slow loss is what makes cigar smoke so dangerous for the lungs.

The idea that cigars are safe for the lungs because the smoker does not inhale is the belief I find most frustrating, because it is so widely believed and so plainly wrong. I have heard it from cigar smokers many times, and I understand why they believe it. It feels logical: if the smoke does not go deep into the lungs, the lungs must be safe. But the smoke does go into the lungs, every time, because a person has to breathe while they smoke, and the room is full of smoke for an hour or more. And even the smoke that stays in the mouth and throat is doing damage, to the mouth, the throat, and the voice box. The belief is a comfort, not a fact, and it keeps people smoking long after their lungs have started to suffer.

A morning cough is the detail I keep coming back to. A healthy person does not wake up and cough every day. A person who coughs every morning, brings up mucus, and then feels fine is not healthy. They are living with airways that are irritated and struggling to clear themselves, and they have decided that is normal. It is not normal. It is the lungs asking for help, in the only way they can. I would rather a person hear that cough as a warning than as background noise, because the warning comes early, when there is still time to stop the damage from getting worse.

I think about the loss of freedom that comes with damaged lungs, because it is a loss that happens so gradually that the person barely notices it. They stop running for the bus. They stop playing football with their children. They stop taking the stairs. They stop going for long walks. Each decision feels sensible on its own, but together they add up to a smaller life, a life lived more slowly and more carefully, because the lungs cannot keep up. That is a high price to pay for a habit that is supposed to be relaxing. A relaxing habit should make life bigger, not smaller, and cigar smoking does the opposite, year by year.

Chest infections are the part of the story that feels most unfair to me. A person catches a cold, and instead of recovering in a few days, they are ill for weeks, coughing, breathless, and exhausted. They miss work, they miss family time, and they feel miserable, all because their lungs cannot clear the infection the way healthy lungs can. And then it happens again, a few months later, and again. Each infection leaves the lungs a little more scarred, and the next one comes a little more easily. It is a miserable loop, and it is caused by smoke that damages the very system meant to keep the lungs clean. Stopping breaks that loop, and the improvement in how often a person gets ill is often the first thing they notice.

What gives me hope is how quickly the lungs start to heal when the smoke stops. The cleaning hairs begin to work again within weeks. The cough that gets worse for a short time after stopping is actually a good sign, because it means the lungs are finally clearing out the mucus they have been holding. The breathlessness eases over months. The risk of serious lung disease falls year by year. I have read enough about this to know that the lungs want to heal, and they start the moment they are given clean air. That is not a small thing. It means the damage is not a life sentence, and a person who has smoked cigars for twenty years can still breathe more easily in a year’s time than they do today, if they stop now.

I also think about children, because their lungs are still growing, and secondhand cigar smoke does real harm to them. A child who grows up breathing cigar smoke at home is more likely to have asthma, to miss school, and to carry weaker lungs into adult life. They did not choose that, and they cannot choose to leave the room. I know that sounds harsh, and I do not say it to make anyone feel guilty. I say it because it is true, and because many cigar smokers tell me they had not thought about it until someone said it plainly. If you smoke cigars at home, the kindest thing you can do for the children in your house is to smoke outside, away from them, or better still, to stop altogether.

Money is a practical reason I think about as well. Cigars are expensive, and a regular habit costs a large amount over a year. That money could go to a family holiday, to savings, or to something that makes life better rather than harder. When a person stops, that money comes back week by week, and the easier breathing comes back with it. It is not the most important reason to stop, but it is a real one, and it helps in the early weeks when the craving is strong and the person needs a reminder of what they are gaining.

I do not think cigar smokers are foolish. Most of them started because cigars were presented as a mark of success, a reward, or a way to relax with friends. The marketing is powerful, and the social setting makes it feel normal. But normal does not mean safe, and a relaxing habit should not leave you coughing every morning and breathless on the stairs. A walk in fresh air, a good meal, and a clear chest are a better way to relax than an hour of thick smoke that narrows your airways and fills your lungs with mucus. I would rather relax with clean air than with a cough.

If you smoke cigars and you are reading this, I would ask you to pay attention to your breathing for a week. Notice how you feel in the morning. Notice whether you cough, and for how long. Notice how your chest feels when you climb stairs, and how long it takes for your breathing to settle. Notice whether cold air makes you wheeze, or whether a laugh sets off a cough. Write it down if it helps. That honest record is more useful than any lecture, because it is your own lungs telling you their own story. If what you notice worries you, talk to a health professional. You do not need to have a plan, and you do not need to promise to quit on the spot. You only need to ask, and to listen.

Finally, I would say this to anyone who has never smoked a cigar: do not start. The first cigar feels like a small thing, a single evening, a single celebration. But the habit it starts is not small, and it is far harder to stop than it is to start. The lungs you have now are the lungs you will need for the rest of your life, and they deserve clean air. Protect them now, while the choice is easy, and you will never have to undo years of damage later. That is the simplest advice in this whole article, and it is also the most valuable.

I think about the way cigars are sold, because the selling is part of the problem. They are placed in wooden boxes, wrapped in gold bands, and priced like a luxury. The shop smells of leather and cedar, and the person behind the counter talks about flavour and origin as if they were selling fine wine. None of that changes what is in the smoke. A luxury box does not make tar less sticky in the airways, and a gold band does not make the cleaning hairs in the lungs less likely to be damaged. The luxury is a story, and it is a story that costs people their breath. I would rather see cigars sold honestly, with the risks plain on the box, than wrapped in a story that hides them.

The social side is something I understand, because cigars are rarely smoked alone. They are smoked with friends, after a meal, at a wedding, or on a holiday. Saying no in that setting feels awkward, and nobody wants to be the person who spoils the mood. But a real friend would rather you said no than watch you damage your lungs for the sake of fitting in. If your friends care about you, they will respect a decision to stop, and many of them may be thinking about stopping themselves. The hardest part is being the first person to say it out loud. Once one person says it, others often follow, and the evening becomes easier for everyone.

I also want to be clear about quitting itself, because the fear of failing stops many people from trying. Most people who quit successfully have tried before and failed. That is normal, and it is not a reason to give up. Each attempt teaches something: which evenings are hardest, which friends trigger a craving, what helps when the urge comes. A failed attempt is practice, not a verdict. If you tried last year and went back to cigars, that does not mean you cannot quit. It means you learned something, and the next attempt will be stronger because of it. I would rather you tried five times and succeeded on the fifth than never tried at all.

Support makes a real difference, and I would urge anyone who smokes cigars to use it. Talking to a doctor, joining a quit programme, or simply telling family and friends that you are stopping all make success more likely. You do not need to do this alone, and doing it alone is the hardest way. There is no shame in asking for help. Athletes have coaches, students have teachers, and people who want to quit smoking deserve support too. The help exists because quitting is hard, not because you are weak, and using it is a sign of sense, not a sign of failure.

One more thing I think about is how much the lungs give us without being asked. They breathe twenty thousand times a day, without rest, without complaint, for our whole life. They ask for very little: clean air, and time to clear themselves when they are irritated. Cigar smoke asks them to do that same work with swollen airways, damaged cleaning hairs, and mucus that will not move, and they do so without protest, until the day they cannot. I find that loyalty moving, and I think it deserves better. Giving your lungs clean air is the least you can do for organs that have never stopped working for you, and it is a gift that starts paying you back within weeks.

I would also ask you to remember that your lungs do not need a grand gesture. They do not need a perfect life, a perfect diet, or a perfect exercise plan. They need small, steady choices, made day after day: clean air instead of smoke, a walk instead of a chair, a check-up instead of a guess. Stopping cigars is one of those small choices, and it is one of the most powerful. You do not need to fix everything at once. You only need to start with the smoke, and let the rest follow, one honest step at a time.

Frequently Asked Questions

How does cigars affect the airways?

Cigar smoke irritates the lining of the airways, causing swelling, extra mucus, and tightening of the muscles around the tubes. That irritation makes the airways narrower, so air moves more slowly in and out, and breathing takes more effort. Over time, the smoke damages the tiny cleaning hairs inside the airways, so mucus stays in place and germs can settle there. Anyone who notices persistent coughing, wheezing, or breathlessness should take the pattern seriously and talk with a health professional.

Can cigars cause weaker lung capacity even in light users?

Yes, the risk is lower than for heavy daily users, but it is not zero, and shorter breath has been reported by people who use cigars only a few times a week. A single large cigar contains a large amount of tobacco, and even occasional smoke irritates the airways and damages the cleaning system in the lungs. The body responds to repeated exposure, and light use repeated over months still counts as repeated exposure. Less use means less strain, while no use means the strain stops growing.

How long does it take for cigars to harm coughing?

There is no single timetable, because bodies, habits and amounts differ, yet shorter breath can appear within weeks for some people and build slowly over years for others. A morning cough can begin after a short period of regular smoking, while serious loss of lung capacity takes years to develop. What matters more than the exact date is the direction: the longer cigars are used regularly, the more likely the airways are to show the strain.

Does stopping cigars help the chest recover?

In many cases yes, and the first change people notice is often that breathlessness stops getting worse, followed by a slow improvement in the chest over weeks and months. Within a few weeks of stopping, the cleaning hairs in the airways begin to work again, and the lungs start to clear mucus properly. Recovery is not instant and it is not the same for everyone, and some harm takes much longer to ease. Even so, stopping removes the daily irritation, which gives the lungs their best chance to repair themselves.

Why do people keep using cigars if it harms coughing?

Habit, routine, social pressure and the quick feeling cigars give all play a part, and shorter breath arrives too slowly to feel like an immediate warning. Many people also use cigars to cope with stress, tiredness or low mood, which makes the habit feel useful even while it weakens the lungs. The belief that cigars are safe because the smoker does not inhale also keeps people smoking. Understanding that loop is often the first step toward breaking it, with support from family, friends or a health professional.

When should someone seek advice about cigars and lung capacity?

It is sensible to seek advice when shorter breath keeps returning, when breathing interferes with work, sleep or family life, or when stopping cigars feels very hard. A health professional can give general information, check for other causes, and explain the support options available. Seek urgent help if you notice severe breathlessness, chest pain, or coughing up blood. This article is general information only and is not a substitute for personal medical advice.
