'Rare, But More Deadly'

Premium

Though it is rare, men can get breast cancer, too. But whereas women and their doctors know to be vigilant in looking for signs of the disease, men and their doctors often ignore signs and symptoms, or don't know what to look for, leading to a higher rate of disease-related mortality in males than in females, says the Associated Press' Lindsey Tanner. Researchers have found that on average, women with breast cancer live two years longer than men with the same disease, and that men's tumors are likely to be larger, more advanced, and are more likely to have metastasized by the time they're diagnosed, Tanner says.

And because the disease is so rare in men, it is not very well-studied, Tanner adds. Some researchers say there is evidence to suggest that men's tumors are biologically different from women's and should be treated differently, but the lack of strong evidence to that end has made it difficult to know for sure to date.
