The reality star and fitness guru posted an Instagram photo Sunday showing a small mole on the side of her butt, along with an emotional message to her followers.
"I work out hard for this Booty. I was planning on competing again in November at 50 years old, but I'm not sure that's happening now," she wrote. "It looks like God has a different plan for me. Im showing you this picture because this is what melanoma looks like. I don't want sympathy, I want you to save YOUR ass and get your skin checked. This was just a small black flat freckle.... I had no idea!"
Judge -- who just renewed her wedding vows with husband Eddie in Aruba earlier this month -- turns 50 on Sept. 2. She assured her fans her faith is strong and encouraged them to get their skin checked.
"Ill be fine because my faith is strong and my Ass ain't bad either," she wrote. "Thank you @cacoastalderm. I've been a little sad, worried and pissed off. But we caught it early and that makes me happy. Happy birthday to me. #saveyourass birthday party in Cabo not sounding like a good idea now. #awareness. #skincheck"
