I know that breast cancer in men is rare, but do men with manboobs have a higher rate of breast cancer than men with no manboobs?
Unproven: Men can have prominent breast tissue due to obesity (lipomastia) or a condition where there is increased glandular tissue--gynecomastia. It is often stated that gynecomastia is associated with increased risks of breast cancer, but no study has ever proven this. We do know, however, that high estrogen states can increase the risk of breast cancer in men (or women) and can be a cause of gynecomastia. ...Read moreSee 1 more doctor answer

What are the chances of having colon cancer in a 36 year old man with no history of colon cancer in his family?
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. ...Read more

An oncologist can help look at studies for more results. ...Read moreSee 1 more doctor answer
