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

Both my uncle&my dad had lung cancer&lymphoma at the same time is this rare&could it be genetic?Many males have died from same for generations back!

Any specific occupation (i.e. Miners or coal workers or other?) i'd be much bore suspicious that your dad and his brother were exposed to something that led to the diseases. ...Read more

Which gene?: Egfr t790m's actual risk is unknown since nobody knows how many people without lung cancer carry the mutation. Even li fraumeni doesn't approach a 1/3 risk of lung cancer. And what would you do with this information if you had it? Hopefully you will always be a non-smoker. ...Read more

My mom is a rare case right lung has nsclc removed one third of lung cancer free but the left one has sclc  doc ordered six and half weeks of radiatio?

Reasonable: It is possible to have two different lung tumors at the same time. If there is no evidence of cancer outside the chest a combination of radiation and chemotherapy together would be the best proven therapy for the small cell lung cancer. ...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
