Young people are much less likely to get cancer, and there are all sorts of other things the lump could be. But the only sensible thing to do is show it to your doctor and get a professional opinion. If it IS something serious, your chances are much better the earlier it’s diagnosed.

Breast cancer is a cancer that starts in the cells of the breast in women and men. Worldwide, breast cancer is the second most common type of cancer after lung cancer (10.4% of all cancer incidence, both sexes counted) and the fifth most common cause of cancer death
In 2005, breast cancer caused 502,000 deaths worldwide (7% of cancer deaths; almost 1% of all deaths).

Breast tissue that is milk producing is often called mammary glands. Breast tissue may be described as having multiple mammary glands, or may be described as having a single mammary gland that is composed of nodes called lobules. These lobules join together to form a milk duct, which can produce milk.

Breast tissue affected is usually one or more of the undeveloped mammary ducts. To be on the safe side, men should probably perform a breast self-exam every few months to rule out this rare but dangerous form of cancer.
