What causes scar tissue on lungs?
350655
Possible causes of increasing scar tissue being seen on a CT scan are:\n· any of a variety of interstitial lung disease (ILD);\n· a chronic infection with fungi or nontuberculosis mycobacterium, or;\n· neoplastic disease.\n\nILD is swelling that leads to scarring of the lungs in the area between the air sacs and the blood vessels. It may be due to toxic fume exposure, lung infection, connective tissue or autoimmune disease such as arthritis. Scarring of the lungs can happen even without exposure or other risk factors. Most of the time it is not possible to determine exactly what has damaged the lungs. The most common symptoms are an ongoing dry cough and shortness of breath, especially with exercise.

no need to worry . it happens during the course of pulmonary  TB [lung T  B ] IT RESOLVES ON ITS OWN . KINDLY CONTINUE THE FULL COURSE OF TREATMENT

could be something with your lungs, your pecs, or it could be heartburn, or your heart.  if you don't trust your doctor get a second opinion

Occupational exposure to any fumes and/or chemicals can create inflammatory responses within your lung tissue. When this inflammation occurs on a daily basis over a several year period, your lung tissue, specifically the parenchyma will become damaged similiar to that of a chronic smoker. The parenchyma is the distal portion of your lungs that partake in gas exchange (Co2 and 02), when this layer of blood vessels and tissue become destroyed, there is no way to repair the damage. Just think of a coal miner's lung

In normal breathing, air is drawn in through the bronchial passages and down into the increasingly fine network of tubing in the lungs called the alveoli, which are many thousands of tiny sacs surrounded by capillaries. These absorb the oxygen and transfer it into the blood. When toxins such as smoke are breathed into the lungs, the particles are trapped by the hairs and cannot be exhaled, leading to a localised inflammatory response. Chemicals released during the inflammatory response (trypsin, elastase, etc.) begin to break down the walls of alveoli (alveolar septum). This leads to fewer but larger alveoli, with a decreased surface area and a decreased ability to take up oxygen and lose carbon dioxide. The activity of another molecule called alpha 1-antitrypsin normally neutralizes the destructive action of one of these damaging molecules.\n\nAfter a prolonged period, hyperventilation becomes inadequate to maintain high enough oxygen levels in the blood, and the body compensates by vasoconstricting appropriate vessels. This leads to pulmonary hypertension. This leads to enlargement and increased strain on the right side of the heart, which in turn leads to peripheral edema (swelling of the peripherals) as blood gets backed up in the systemic circulation, causing fluid to leave the circulatory system and accumulate in the tissues.\n\nEmphysema occurs in a higher proportion in patient with decreased alpha 1-antitrypsin (A1AT) levels (alpha 1-antitrypsin deficiency, A1AD). In A1AD, inflammatory enzymes (such as elastase) are able to destroy the alveolar tissue (the elastin fibre, for example). Most A1AD patients do not develop clinically significant emphysema, but smoking and severely decreased A1AT levels (10-15%) can cause emphysema at a young age. In all, A1AD causes about 2% of all emphysema. However, smokers with A1AD are in the highest risk category for emphysema.

Sounds like the doc said, an inflamation, maybe caused by an infection.  I've had it a few times, but normally following a rib injury, which does not have to be major. You don't breathe properly, or cough, so the air in the bottom of the lungs gets stagnant.

The constant exposure to irritants, tar etc.. causes the alveoli ( the air sacs inside your lungs that expand when you breathe in ) to lose their elasticity...as a result less oxugen is absorbed in these sacs resulting in a shrinking, hardening of these sacs, and a decrease of oxygen intake.  This is why most emphysema patients are on oxygen to help them breathe......This is emphysema

basically the lungs cant function and become "fibrotic" or very hard.

Collapsed lung(s) can leave scars in the tissue.  After time, these scars harden and cannot be fixed.  The alveoli sacs become damaged and can no longer transfer oxygen and carbon dioxide. Because of this, the rest of the lung has to breathe harder to get more air into the body which in turn creates stress on the heart and brain cells.  There is no cure.  My best wishes.  there is of course a chance something else is going on..please see a dr.

I believe they are caused by body parts that rub up against each other such as your arm rubbing up against your chest. I don't have any website to prove it...Sorry.

First of all, when you think of lung collapse it isn't the entire organ that collapses. There are tiny air sacs in the lung called Alveloi. There are numbers of these alveloi in your lung. Everybody has some of these air sacs collapsed all the time. It is very small and doesn't effect everyday life.\n\nThere are many reasons that can cause the lung to collapse. Trauma, post surgery, pneumonia or other pulmonary infections, masses or tumors, air or fluid between the chest wall and the lung. \n\nThe reason that they can 'build back up' is that the alveloi are like balloons. If you can get air back into the air sacs with breathing exercises and other measures then they open back up.\n\nHope this helps

"intra" alveolar hemorrhage is a medical term which describes how the alveoli, which are the major functioning mechanism in your lungs, are bleeding from inside themselves.  "intrabronchial" hemorrhage is a rupture in the tube or tubes that carry air into each individual lung.  Usually cancer is the reason for this.  The cells inside the lungs are growing too rapidly and expand too wide for normal capacity and rupture inside the infected cells.  It would be interesting to know what the history and symptoms the patient was presenting before the death, or did it just occur randomly.  Also you may want to post a question in the lung section of this site...if they have one, I'm not sure

OKay No! You are not born with emphysema! Ugh! 1st year med school, repiratory physiology.  Emphysema is a term used when the elasticity of the lungs reaches a certain level.  Like it or not, as you get older, your lungs lose elasticity.  Like your stretchy pants.  When you lose so much elasticity, that the lungs hardly deflate, they dub the condition emphysema.  Stem Cell Theapy.  Well, when such a therapy exists, it probably will not work.  Stem cells can replace cells, but it cannot replace the framework of your lungs that was made when you were born.

I think almost all cigarettes do this. They create small tears in the lungs to absorb the chemicals faster.

it maybe  what they call a calcified granuloma which would show up as a spot on your lung but that is nothing harmful lots of people have them and they can tell by a chest xray if thats what it is. your doctor is probably right but it would also help if you said your age and what kind of doctor it was that told you that. Also a radiologist probably read the xray sometimes you can get to talk to them about it. Don't panic because it probably is nothing but if it would make you feel any better get a second opinion and/or ask if you can see a pulmonologist (lung doctor).  When it comes to YOUR health you can't be too cautious. If you have any more questions send me a message

It means that there is a spot in the lungs. That report by itself does NOT tell the cause of the spot. Often not cancerous and can be due to infection or scar tissue. Further testing usually needed to determine if cancer or not.
