Can Mold Cause Lung Cancer
Yes: They're not so deadly as cigarettes because people smoke fewer and the smoke is so disgusting that it's not much inhaled. However, I'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'd had to be a husband who had to live with that one. ...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
Probably not: There is no evidence of a direct link between lung infection and cancer. Chronic inflammation (eg. Emphysema and, to a lesser degree, chronic bronchitis) confers a risk of lung cancer. There is a weak link between a history of pneumonia and a 15-20% higher risk of lung cancer, but compare that to 40 years of smoking, which increases the chance of cancer by 2500%. Its all relative. ...Read moreSee 1 more doctor 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. ...Read moreSee 1 more doctor answer
Many ways: Smoking accounts for the vast majority (but not all) cases of lung cancer. Cigarette smoke contains many substances (carcinogens) that predispose to cancer. They do this in different ways, like interfering with normal lung cell functions, making them divide more rapidly or die more slowly, or by suppressing the normal immune response to tumors. Don't smoke. ...Read more
Concur: I generally agree with good responses of drs swamy and rutledge. Radon is a known and significant carcinogen. Furthermore, numerous inhalants, including many products of burning/combustion are considered carcinogens related to lung cancer. Lung cancer like other cancers is closely related to intensity and duration of exposure to carcinogens/injurious substances. Drswamy provided good link. ...Read moreSee 2 more doctor answers
No, not rectal type: Mycotoxins (the toxic chemicals made by some molds or fungi) can be harmful to humans and animals. Aflatoxin is a well known mycotoxin that can be found in cereals, spices, tree nuts, and animal feeds, so foods are screened to check for contamination with aflatoxin. The aflatoxin can cause liver disease and liver cancer. Mold is not known to cause rectal cancer. ...Read moreSee 2 more doctor answers
Mesothelioma (lung): No doubt. Asbestos exposure - especially long term - causes mesothelioma. It is not safe and harms health in many ways, but there is no established connection to any of the thyroid cancers. Here's a related link: http://scottieleemeyers.Com/2012/01/05/post-office-employees-battle-thyroid-cancer/ best wishes for your health. ...Read moreSee 1 more doctor answer
None identified: In almost four decades in pathology, i've never heard of a chemical that causes that rarest of rare primary cancers -- primary cardiac cancer, usually an angiosarcoma. In fact, i'm the discoverer of one of the rare heart tumors. Therapeutic radiation is the one carcinogen i'd think could increase the risks for the angiosarcs, but i couldn't find a series to confirm this. ...Read more
Varies: Most patients who die of lung cancer develop metastatic disease, or cancer in organs other than the lung. Common sites include the bones, brain, and liver. As the tumor grows, the functioning of these organs is compromised. This can lead to death. Patients also have a general decline, with cachexia frequently due to substances called cytokines released by the cancer. ...Read more
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
