'Shark Tank's' Daymond John reveals thyroid cancer diagnosis

“Shark Tank” star and entrepreneur Daymond John has revealed he recently had a mass removed from his thyroid that turned out to be stage two cancer.

“You know, I didn’t skip a beat,” John told Robin Roberts on “Good Morning America” on Wednesday, opening up about the health battle. “I went to and I got some early detections, and I understood that I had a challenge and if I would attack it now, then I wouldn’t let it attack me.”

John said he was out “partying and dancing” two days after having the cancerous nodule removed.

“I am absolutely great,” he said about his health these days. “I have to monitor [it] the rest of my life. You know, I have another half of my thyroid still in, and in the event that it comes back, I'll be able to fight it. Thyroid is a very slow-growing cancer.”

John said he decided he wanted to go public with his cancer experience to help others.

"I'm good and 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."

The father-of-three daughters said he was proactive about his health because of his children.

“I want to be there to walk them down the aisle,” he said. “…"And this is how it happens, by going out and people getting mammograms, colonoscopies...and all the things to find out what's going on. Because you can prevent this, and you can stay around in your family’s life."

John is the CEO of the highly successful fashion brand FUBU. He’s been on ABC’s “Shark Tank” since 2009, and the hit show is nearing its 200th episode. It also stars Mark Cuban and Kevin O'Leary, among others.
