Breast cancer on the rise among men, report researchers who conducted a study, which includes data from 1973 to 1998. It shows that the incidence of breast cancer in men climbed from 0.86 cases per 100,000 men over age 25 to 1.08 cases during the 25-year study.
Researchers say that breast cancer in men is poorly understood, mainly because the disease is so rare among males, accounting for less than 1 percent of all cancers in men. Doctors aren't sure how the disease develops, which treatments are best, or how it progresses.
Researchers analyzed data from a National Cancer Institute registry , they found that an increasing rate of breast cancer among men, they also found that men are more likely to be diagnosed with the disease at a older age than women and generally have more advanced disease upon diagnosis. Other clinical factors vary as well, but overall survival is about the same for both sexes.
Thus researchers conclude that the incidence of breast carcinoma in men has increased from 1973 to 1998 although, overall, it remains a rare condition.
