Male 21. Non smoker active lifestyle. I seem to be getting frequent colds with little cough about every other month. How likely is lung cancer?

Essentially zero: Although there is some data suggesting that lung cancer occurs at a bit younger age in never-smokers compared with smokers, in the absence of (for instance) immune system deficiency or underlying lung disease or the presence of cancer elsewhere in the body which could spread to the lungs, the likelihood of lung cancer at age 21 in an otherwise healthy non-smoker is virtually zero. ...Read more

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
