Taboo of the Black Eyed Peas is opening up about his secret battle with testicular cancer.

Jaime Gomez, 41, says he checked into an emergency room in 2014 after having pain throughout his body after a show and found out that he had stage 2 testicular cancer.

“I was in good shape,” he told Forbes in an interview, calling his chemotherapy treatments "grueling."

“I ate healthy foods, worked out, and even with all that healthy living, it happened," he continued.

The rapper underwent surgery and a 12-week course of chemotherapy before being declared in remission last year.

“A lot of people have a misconception about artists, that they’re invincible...they’re on a different plateau," he told The Doctors in an interview. "But I’m just a human being. I’m a normal person just like everybody else. I just may have a different job. But I have kids, a wife, I bleed, I went through cancer.”

Taboo's struggle with cancer inspired his new song, The Fight, with a portion of the proceeds supporting the American Cancer Society. Taboo was named an ACS ambassador in May.
