Actor Richard Roundtree, who starred as Shaft in the 1971 movie, was diagnosed with breast cancer at age 51. A double mastectomy and chemo saved his life.

Peter Criss, the drummer for the band KISS, was 62 when he was diagnosed in 2014. "You don't need boobs to get breast cancer," is his message to other guys. 

And 84-year-old former NFL star Ernie Green was diagnosed at age 67 — when he went for a second opinion, after his regular doctor dismissed his concerns about a lump in his breast.

They're all lucky to have survived, because male breast cancer is usually diagnosed late, when it’s more dangerous. Around 2,350 men are diagnosed with breast cancer in the U.S. annually, and 440 die from the disease.

At Cedars-Sinai's cancer center, the specialists recommend any man with a family history of early-onset female breast cancer, with more than one family member who has had female breast cancer, or if he is of Ashkenazi Jewish ancestry get a genetic test to check if he is BRCA2 positive.

And guys who have had metastatic, high- or very high-risk prostate cancer, or who have already had breast cancer should get tested too.

Being BRCA2+ raises the risk of a man developing breast cancer from 0.1% to 7%, and boosts the risk for prostate and pancreatic cancer.

And if you have a painless lump, nipple discharge, and/or an inverted or sore nipple, see an oncologist. Don't assume, as Roundtree did initially, "women die from this, not men. How could I possibly have that?"
