Daymond John, CEO of FUBU and longtime "Shark Tank" star, revealed during a sit-down interview with "Good Morning America" on Wednesday that he was diagnosed cancer of the thyroid and has received treatment for it.
Doctors removed a cancerous mass from this thyroid, which they discovered after an extensive physical.
"They removed it and it was stage 2 cancer on my thyroid ... I didn't skip a beat. I got some early detection and I understood that I had a challenge and if I attack it now, then I wouldn't let it attack me," he told Robin Roberts. "I had that removed. I didn't miss anything, I was out partying and dancing two days later -- not that I should of."
The 48-year-old businessman stressed the importance of early detection, which is a huge reason why he's sharing his story with the world.
"But I wanted to share this information with people, because what would I have went through if I decided to just stick my head in the sand and go, 'You know what, I'm not going to check into stuff. If it happens it happens to everybody else,'" John said.
And while the situation could have been significantly worse, even life-threatening, it was his decision to act quickly that saved his life. Now, John is "absolutely great," although he'll have to have routine checkups to see if the cancer has returned for the rest of his life.
"I have another half of my thyroid still in. In the event it comes back I will have to fight it," he revealed.
John, 48, is the CEO of the famed FUBU corporation and an investor on the hit ABC show, which he's starred on since 2009.
