Does Fiberglass Insulation Cause Lung Cancer
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
Short answer...: No. While asbestos increases the risk of lung cancer, most exposed individuals don't get lung cancer or any of the other problems linked to asbestos. Think of it like this, most traffic deaths occur in people in cars, but most people who drive/ride in cars don't die in accidents. Not the perfect analogy, but it helps convey the difference between exposure to a risk factor and getting the disease. ...Read moreSee 2 more doctor answers
Yes, tobacco use in: Any form increases the risk of cancer. The risk of lung cancer in pipe smokers is not as high as in cigarette smokers, but is higher than in non-smokers. See this site for more info. http://www.cdc.gov/cancer/lung/basic_info/risk_factors.htm. ...Read moreSee 6 more doctor answers
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
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
One step: When k-ras takes a mutation that makes it stuck on the "on" position, it confers an unfair growth advantage on the cell and its progeny. Kras mutated lung cancers tend to occur in smokers and make mucin. There's no medicine right now that works especially well for this subcategory of cancers and its presence suggests other good target mutations are probably not present. Good luck, stay proactive. ...Read more
Chemo brain: Chemo brain has been studied fairly well and in fact at this past years national conference a seminal study was presented that notes that chemo brain can begin even before a patient has received any chemotherapy. Thus the cognitive impairment begins from the traumatic stress caused by the diagnosis and hearing the words chemotherapy and cancer. This is a form of ptsd. Some ctx makes it worse. ...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
Lung cancer: The different cell types of lung cancer have the propensity to spread to different organs either due to blood stream patterns, adjacent anatomy or the affinity of these other organs to receive and grow these cancer strains. It turns out that the brain is one of those susceptible organs. ...Read moreSee 1 more doctor answer
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
Lung Cavity Causes: Not at all! differential DX of cavitation on chest x-ray: 1 caveating pneumonia: s aureus, gram-negative bacilli (klebsiella, pseudomonas, legionella), anaerobes, mycobacteria, fungi, pneumocystis. 2 septic emboli, bacterial or fungal. 3 wegener's granulomatosis or pulmonary infarction 4 infected bullae or cysts. 5 cancer: primary or secondary. Clearly, your doctor will help sort these out. ...Read moreSee 2 more doctor answers
Brain Mets: (metastasis) as an entity comprise 100k per year. Lung cancer leads the league, but breast, melanoma, kidney are quite common. Prostate almost never. Only rhabdoid tumors in children commonly go to brain. This pattern stares at us, but baffles us as to why "organotropic" patterns of metastasis are so predictable. ...Read more
Scarring: As the lungs scar and lose volume, both the vital capacity and residual lung volume decrease. That is the nature of restrictive lung disease. ...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
