A member asked:

What is the likelihood of lung cancer in a 22 year old athletic male non smoker?

A doctor has provided 1 answer

Risk: Lung cancer usually requires multiple "hits" to the genes in your cells before the cells become fully malignant. Statistically, this requires exposure to carcinogens, enough time to increase the odds, and still some bad luck. Reducing risk factors by eliminating smoking and other exposures (asbestos, radiation, etc.) are good habits to start when you are younger.
