How serious is breast cancer in men?

Doctors used to think that breast cancer in men was a more severe disease than it was in women, but it now seems that for comparably advanced breast cancers, men and women have similar outcomes.

The major problem is that breast cancer in men is often diagnosed later than breast cancer in women. This may be because men are less likely to be suspicious of an abnormality in that area. In addition, their small amount of breast tissue is harder to feel -- making it more difficult to catch these cancers early, and allowing tumors to spread more quickly to the surrounding tissues.
