Question 1

if you had an "occult" lung cancer causing fatigue and muscle loss,how do you find it or even confirm that it is an occult tumor. sounds tricky.thanks?

Accepted Answer

A high resolution: CT scan of the thorax should reveal the answer.

Question 2

what causes lung cancer?

Accepted Answer

Mainly smoking: But a lot of other factors (most of which can nit be altered) may play a role. Over 85% of lung cancers are seen in smokers, so if you would like to decrease your chances of getting lung cancer (and also cardiovascular disease!) quit smoking now!

Question 3

could car fumes cause lung cancer?

Accepted Answer

Not likely: The vast majority of lung cancer is caused by smoking - i.e. First hand cigarette smoke. Lung cancer is rare in people who have never smoked. If car exhaust were an important contributor we'd see far more cancer in people who had never smoked.

Question 4

what is the usual cause of lung cancer?

Accepted Answer

Smoking: Tobacco smoking is the usual cause of lung cancer. About 10% of lung cancers may occur in non-smokers. Second hand smoke and exposure to radon gas are the next important causes. Of course genetic susceptibility always plays a role in all diseases, including lung cancer.

Question 5

what is lung cancer caused by in nonsmoker?

Accepted Answer

Possibly genetic,etc: Nonsmokers account for 15% of lung cancer cases, and these cases are often due to a combination of genetic factors, radon gas, asbestos, and air pollution including secondhand smoke.  Asbestos can also cause mesothelioma, a cancer of the pleura or lining on the surface of the lungand diaphragm.  The main type of lung cancer in nonsmokers is adenocarcinoma, particularly bronchoalveolar carcinoma.

Question 6

need expert help here. what are the symptoms and causes for lung cancer?

Accepted Answer

Familiar: Cough, weight loss, chest discomfort, pneumonia, just not feeling well. Smoking, smoking, asbestos exposure, maybe radon exposure especially if you smoke, working in a uranium mine, smoking, certain chemicals such as chromates in the workplace, urban pollution maybe, passive smoking (i've autopsied two wives who died from living in smoke-filled homes with stogie-puffing husbands.).

Question 7

can cigars cause lung cancer?

Accepted Answer

Yes: They&#x27;re not so deadly as cigarettes because people smoke fewer and the smoke is so disgusting that it&#x27;s not much inhaled. However, I&#x27;ve autopsied two non-smoking wives of heavy cigar smokers who died of smoker-type lung cancer -- my only non-smoker lung cancer autosies. I&#x27;d had to be a husband who had to live with that one.

Question 8

does hairspray cause lung cancer?

Accepted Answer

No, not really: Hair sprays are considered safe.

Question 9

how can  smoking cause lung cancer?

Accepted Answer

Toxins: Irritation, tar and other hundreds of impurities in the cigarettes.

Question 10

how can air pollution cause lung cancer?

Accepted Answer

The same way cigs do: Any high level inhalation of hydrocarbon combustion prodicts (tobacco, diesel, wood stove) can lead to cancer, but obviously with cigarettes you are looking at enormous amounts of combutsion product over many years. Urban dwellers get lung cancer at a higher rate than rural folks, but the effect pales compared to the effect of smoking.
