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. " 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.
