Mike, like most men had no idea he could even get breast cancer but health officials say an estimated 2300 men in the U.S. are diagnosed with it each year and about 450 men die from the disease. “I’m going to die from the cancer. I know that but there is no time frame for it,” Selsman said.

His wife Kara is a breast cancer survivor. Together they are battling this disease and getting their message across. “I want men to know they are susceptible to breast cancer it’s not just a women’s disease,” Kara said.

In 2012 the Selsmans took their fight to state house and were able to get the third week in October designated as Male Breast Cancer Awareness Week. “It’s not just for women though and men have to know it can happen pay attention and try and catch it early. I want people to get ahead of me of where I was when I found out and have a better chance to live longer and be cured,” Selsman said.
