Men's Breast Cancer

“In the general population, it’s very rare,” points out Aggarwal, noting that fewer than one percent of breast cancer cases occur in men. She says it’s on the rise, though, with data showing a 26 percent increase from 1975 to 2010.
Scientists don’t yet have a handle on why that is, but they do know that men with breast cancer are typically diagnosed at a later stage than their female peers.
“With men, there’s a delay in detection,” says Aggarwal. “There’s less awareness, no screening. And men don’t palpate their breasts every month, as do many women. All these factors combine.”
