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

What does lung cancer have to do with homeostasis?

What does lung cancer have to do with homeostasis?

Artificial question: All cancers are the result of accumulated genetic mutations in a line of cells, and unless you are treated with surgery, radiation and/or evidence-based chemotherapy for lung cancer, it will kill you. The word "homeostasis" is misused by charlatans. Anyone who tells you otherwise, or that they have something that "will restore homeostasis naturally" without scientific rx is deceiving you. ...Read more

Unlikely but: Given that you are a non-smoker it is unlikely that your pain is due to lung cancer. However, we definitely see lung cancer in never smokers.

Can I ask why bronchiectasis increases risk of lung cancer? I heard that there is a link and increased risk but don't understand how n why this happens

Could be: Suggest pulmonologist to answer. Since both conditions are associated with smoking, I would not be surprised, but how this applies to you is another matter. I'd actually see a pulmonologist locally to review your lung CT or MRI in detail. Make noise. I encourage asking questions. ...Read more

How do you get lung cancer? If you don't smoke? Myparents smoked, but I always hated the way the stuff smelled. When I got older, I made them go outside to smoke, and I haven't been around smokers in years. Sohow could I have lung cancer?

I: I agree with dr. Leeman's answer entirely. Clearly, the most common cause of lung cancer is due to cigarette smoking.

As an added piece of information, exposure to radon gas, usually by way of poorly vented basements, is one of the more likely causes of lung cancer when smoking is not a factor. You live in cook county, illinois and in general, it is listed as a county with moderate potential for levels of radon (in the range of 2-4 pci/l). You may want to have your home assessed for radon levels and if they are elevated have a reputable radon mitigation company discuss options for your home - usually a simple venting system is all that is needed. ...Read more

If a person had lung cancer, they couldn't feel the tumor when they take deep breaths, could they?

Usually not: Most lung cancers start in the interior tissue of the lung where there are no pain nerves. If the tumor, or its metastases, involve the outer lining of the lung (where there are pain nerves), one can then feel pain on breathing. Other medical problems (like pleurisy) can also cause pain on breathing ...Read more

For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.

I have chest pain in the center, when ibow down. It is rare and it doesn't happen when I breathe. I have painin the back, like a circle. Is it lung cancer?

Unlikely: The pains that you feel need to be evaluated for what is causing them. Lung cancer is usually initially without much pain except for irritation of airway maybe but are found most of the time accidentally when looking for other things or as part of screening. Look at your risks for it and be screened and look for causes of the pain. If they happen to correlate then you find out. ...Read more

Do air purifiers (or air cleaners) reduce a person's chance of lung cancer? Would having high quality air purifiers at home and in my office at work reduce my chance of getting cancer? I live in an area with bad air pollution. I don't know if these devic

Unknown, can't hurt: The best way to reduce the risk of lung cancer is to avoid tobacco smoke, either smoking yourself or second hand smoke. In areas with high pollution, hepa filters may sounds reasonable but unless you live in a bubble you'll still be exposed to inhaled pollutants. There is no evidence that filters prevent lung cancer, but may help other issues like allergies, asthma, and general qol! ...Read more

Lung (Definition)

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
