Cigarette Cancer Smoking
So what specifically is happening when a heavy smoker begins to get recurring pleuritis directly caused by the cigarette smoking? No cancer or asthma
To attribute recurrent pleuritis to smoking cigarettes is perhaps problematic. I'm not an expert in recurring pleuritis but I would be looking for other possibilities. Chronic coughing might make irritation of the pleura more likely but I'm not aware of the chronic bronchitis so common in smokers being the source of pleuritis
you may have heard this from someone who knows more than I or not. ...Read more
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body.

No real difference: What counts is the total amount of tars and other carcinogenic substances found in smoke, not whether you use one brand or twenty. Some brands have more tars than others, but it depends as much on your smoking pattern (holding low tar cigarettes right around where the filter begins shuts off the tiny holes in the paper and increases tars), including how deeply you inhale, how long you hold it etc ...Read more

Nobody truly knows: But the chronic irritation of certain aromatic hydrocarbons in the smoke ("tars") progressively irritates cells, increases the number that die, with new ones taking their place that over many years become more and more abnormal (metaplasia), finally becoming very abnormal (dysplasia) and ultimately becoming cancer (neoplasia). I do not know the exact cellular mechanisms, but some scientists do. ...Read more
