A host of one of TV's most popular reality shows is opening up about his recent cancer diagnosis.

After 200 episodes of the popular reality show - where entrepreneurs try to get one of the "sharks" to invest in their idea - lots of viewers feel a special connection to the hosts, which is why he decided to discuss his condition publicly.

But he also hopes that increasing awareness about thyroid cancer will encourage more people to be proactive about their health.

Daymond John, the founder of clothing company FUBU, who's been a shark since the show debuted in 2009, revealed his diagnosis during an interview on Good Morning America this week.

John's doctors found a nodule on his thyroid last year and continued to monitor it. Last month the businessman and motivational speaker had an operation to remove the nodule and half of his thyroid.

Like fellow celebrity Sofia Vergara, John wanted to raise awareness about the disease and let his fans know he's doing alright.

"I want to share this with people because that's what success is. It's staying in your family's lives, it's being around," he said.

"If I decided to just stick my head in the sand and go, 'you know what, I'm not going to check into stuff,' I would've really had some big, big problems."

Thyroid cancer is usually very slow and not aggressive. It affects your thyroid, a small gland on the front of the neck that produces hormones to regulate your metabolism.

It's more common in women than men, so you should monitor your cancer risk, but most patients live a totally normal life after being treated.

In fact, John admits he was "out partying and dancing two days [after my surgery]."
