Khloe Kardashian opened up to her fans on her app about her scary skin experience.

"I have moles everywhere, and a couple years ago, I noticed one growing under my breast,” she shared. “I immediately looked it up online and found out that if a mole is growing and changing shape, you should go to the doctor—so I did. They took the whole thing out and they biopsied it."

Fortunately, the 32-year-old “Keeping Up With the Kardashians” star's results came back benign. However, doctors decided to take action in another situation regarding a mole on her back.

"There was one mole I had on my back that was skin cancer. I had 8 inches of skin removed," Kardashian revealed. "It was definitely painful because it was a lot of skin, but most of the time, the removals haven't been that bad. Now that I've gone through this a couple of times, I am extra aware of my skin, body and moles."

And the starlet urged her fans to stay vigilant when it comes to their health.

"I urge you to check yourself frequently!" she wrote. "I haven't had a problem in years, but wanted to share my experience with you so that if you notice something doesn't look right, you will take action and take care of your health!"
