Peter Criss grew concerned after he noticed a small lump in his left breast. When the Catman, as he was known during his days as the make-up smeared drummer for Kiss, noticed that the lump was growing larger and more painful, he decided to see a doctor. After a series of tests, he soon learned that he had breast cancer, the Associated Press reports. Two years and two surgeries later, Criss is cancer-free—thanks to his proactive approach, doctors were able to diagnose and treat the condition early. Now the former rock star is on a mission to educate men about the disease.
