Even with his very messy divorce taking center stage, Tarek El Moussa has a big reason to celebrate.

The star of Flip or Flop revealed that he’s still cancer-free for three years.

“Still cancer-free!!! Having cancer is a very scary thing… I always get nervous going into each check up and today I got GREAT news!! Having no thyroid and balancing medications is tough! I’m finally at UCLA and I’m on the right doses of medication,” he wrote. “People don’t know but I was very over medicated with rapid heart rate and palpitations to the point where I wore a heart rate monitor… It really messed me up but everything is dialed and I finally feel great after three years!”

Tarek was first diagnosed with cancer after a viewer — who happened to be a registered nurse — observed an unusual mass on his neck and wrote HGTV urging the Flip or Flop star to get it looked at.

“I noticed that at certain angles, at certain times, it just caught my eye that Tarek had a lump on his throat,” the observant viewer, Ryan Reade, told Today. “And I thought it was something that needed to be brought to his attention.”

Tarek took the suggestion seriously and saw a doctor; having been a heavy smoker when he was younger, he had written off it off as “just a fatty mass.”

After seeing a doctor and being diagnosed with thyroid cancer, he had his thyroid and lymph nodes removed and began Iodine radiation.

The good news is probably a refreshing change of pace for Tarek, who is going through a nasty divorce with his estranged wife, Christina. As In Touch previously reported, Tarek is said to “have a lot of anger issues.”

“In the early days of filming Flip or Flop, Christina ignored Tarek and looked down at her phone when he tormented her. But when they started fighting more in 2016, she was no longer tolerating him and kept her distance,” a source previously told In Touch.
