Black Eyed Peas singer Taboo has opened up about his battle with testicular cancer.

The 41-year-old rapper underwent emergency treatment in 2014 after suffering crippling pain following a gig.

After discovering he had stage 2 testicular cancer, he had an operation to remove the main part of the disease.

Taboo, whose real name is Jaime Gomez, endured an intense 12-week course of chemotherapy treatment before his remission.

Recounting his shocking diagnoses he told Forbes magazine: "I was in good shape. I ate healthy foods, worked out, and even with all that healthy living, it happened".

Speaking to People magazine, he said: "It all started with a pain in my back and abdomen. The very next day I went into surgery to have the 'mothership' removed. But my fight had just begun."

His family and bandmates rallied around him after learning he had the disease. "Will.i.am instantly reached out to a great doctor who helped me figure out a treatment plan. I was racing against the clock," Taboo revealed, Sky News reports.

Posting a series of images on his Instagram account chronicling his journey back to health, he said it was a reminder to 'keep fighting'.

Paying tribute to this wife and children he said they were his motivation to keep going and "the reason why I am alive today".

The singer, who has been cancer-free for two years, explained that his secret battle with testicular cancer inspired his new solo single The Fight.

70% of money raised from the sale of the track will go towards a new campaign by the charity called The Fight, to help others battling the disease.

"There are millions going through things like this, and I want to remind them that we don't curl up into a ball when we have a trial or tribulation," he said. "We get up and fight."

In May, he was named an ambassador for the American Cancer Society, Billboard reports.
