We’ve heard about TV personalities being thankful for their fans, but Flip or Flop host, Tarek El Moussa, will have to go beyond mere thanks.

The host of the HGTV property-flipping show was diagnosed with thyroid cancer after a Flip or Flop viewer spotted a lump on his neck. No, seriously.

The fan, a registered nurse named Ryan Read, noticed a large nodule on El Moussa’s thyroid while watching a Season 1 marathon of the show. She immediately contacted producers explaining what she thought she saw, and said El Moussa needed to have it checked out, which led to his diagnosis in 2013 at age 31.

Read’s email prompted El Moussa to have a biopsy done, even though he was already told by some professionals that it was benign. It turned out the lump was actually cancerous, and he had to have his thyroid removed. During surgery, doctors saw that the cancer had spread to his lymph nodes, so he was forced to undergo thyroid radioactive iodine therapy. Luckily, the surgeries and treatment worked.

Now 33, his thyroid cancer is in remission, but if it weren’t for Read’s quick thinking and email to the producers, it may not have turned out that way.

“If it wasn’t for TV and her noticing this huge lump on my neck, I would still be moving forward with my life, with cancer in my body and [I’d] probably never do anything about it,” El Moussa told People magazine . “I feel fantastic. I’m in shape, I’m taking all my medicines, and I’m currently in remission. Every day that goes by, the odds of the cancer [recurring] decreases, so we’re really excited for that.”
