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
Good question: 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. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
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
Smoking 15 years took about 30 to 40 cigarettes per week. I just left. That I have chances of getting cancer?
Why chance it: As per the CDC: People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Even smoking a few cigarettes a day or smoking occasionally increases the risk of lung cancer. The more years a person smokes and the more cigarettes smoked each day, the more risk goes up. ...Read moreSee 1 more doctor answer
Serious consequence: Smoking causes more than four in five cases of lung cancer. Lung cancer has one of the lowest survival rates of all cancers. Tobacco smoke contains more than 70 different cancer-causing substances. When you inhale smoke, these chemicals enter your lungs and spread around the rest of your body. Scientists have shown that these chemicals can damage dna and change important genes. ...Read more

Tobacco: When burned produces a number of arylhydrocarbons, and other carcinogens that directly attack human dna leading to mutations. Some are repaired, others propagate over time, mean time, nicotine addicts. The more exposure, probabilistic risk increases for cancer, cardiovascular and lung disease. Evidence is overwhelming indisputable.. ...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
Possibly: The studies are beginning to indicate that e-cigs can cause lung injury. Certain chemicals in the liquid are able to cause lung inflammation. If this inflammation continues over years, damage to the DNA can occur. This represents a similar pathophysiology as what happens with smoking cigarettes. ...Read moreSee 2 more doctor answers
Depends: It depends on many factors, but from the practical standpoint, who cares? The important things are: if you don't smoke (or use any tobacco product), never start. If you do, stop right away. It is never too late. Work hard at it. Don't give someone your hard earned money so you can get sick later. ...Read more
How quickly can you get cancer from smoking cigarettes, but only for like 10 months and not everyday?
What are the chances that I would get cancer from smoking cigarettes? Does everyone who smokes get cancer?
No, not everyone: There are more than 50 million smokers in the US, and about 1 million people a year get cancer, and about half of them will die from it. Over 90% of the 200 thousand deaths per year of lung and head/neck cancer are directly due to smoking, as are many other kinds of cancer (often smoking together with excessive alcohol use). Smoking also kills people from heart attack, stroke and other illnesses. ...Read more
Hey docs, I am wondering what are the chances that i would get cancer from smoking cigarettes only a few times?
Low.: Smoking a few cigarettes (say one pack) is very unlikely to increase risk of cancer. This is not an endorsement for smoking. Tobacco products kill countless people in north america every year. Tobacco is potentially lethal and using tobacco products is dangerous not glamorous. Smoking cessation is good for health and for the wallet, as cigs cost a lot of money. ...Read more
Yes, definitely: Yes, most definitely. The lower lip is one of the most common places in the oral cavity to get oral cancer. It is possible to get cancer anywhere in the oral cavity from smoking. The lower lip also gets a lot of sun exposure, which makes it especially susceptible. Smoking along with drinking alcohol makes things even worse. Best answer is to stop smoking. ...Read moreSee 1 more doctor answer
Unclear: Not enough information available yet, but why take the chance? There is no benefit and plenty of risk associated with putting any smoke in your lungs when you don't have to. Most smoke of any kind contains irritants and potential carcinogens so it becomes a matter of how much for how long to determine risk. ...Read moreSee 2 more doctor answers
How does smoking cigarettes increase the risk of bladder cancer, since the smoke never gets to the bladder?
Yes: Yes. Smoking is clearly a risk factor for bladder cancer (and also a certain type of kidney cancer). The reason this occurs is that we believe that the metabolites are degraded and pass through the urinary tract and through prolonged exposure to these carcinogens, the cells undergo malignant changes. ...Read moreSee 1 more doctor answer
