Khloe Kardashian revealed in a new post on her app that she had a skin cancer scare.

The “Keeping Up With the Kardashians” star said she noticed a mole under her breast growing. After a quick research online, she learned that moles are not supposed to grow and that if they do, they should immediately be checked.

The mole turned out to be benign. However, she had another scare later on, and the result was not positive.

“There was one mole I had on my back that was skin cancer,” Kardashian said. “I had 8 inches of skin removed.”

The reality star added that since then she has become more aware of her body and urged people to get themselves checked as often as they can.

Kardashian, however, is not the first celebrity to share her experience. Here are five other celebrities who have opened up about their battle with the disease.

Hugh Jackman has been battling skin cancer for quite some time now. While the actor had been successful at getting rid of it in the past, the cancer keeps coming back. The actor had his nose treated due to cancer for the fourth time early this year.

Jackman shared his story via Instagram, saying: “An example of what happens when you don't wear sunscreen. Basal Cell. The mildest form of cancer but serious, nonetheless. PLEASE USE SUNSCREEN and get regular check-ups.”

Michelle Monaghan also had a mole which grew, according to Health magazine. The actress told the publication that her Australian husband was the one who alerted her to get her doctor to take a look right away.

Diane Keaton told the Los Angeles Times about the importance of using sunscreen after she suffered from two types of skin cancer when she was younger. The actress said she was first diagnosed with basal cell carcinoma when she was 21, and she later had squamous cell carcinoma.

Neglecting to use sunscreen was also to blame for Ewan McGregor's skin cancer. The actor told People that he had his moles checked and found out that one of them was cancerous.

Speculations of abuse started swirling when Melanie Griffith was spotted sporting a black eye in 2009. Representatives of the actress, however, squashed the rumors immediately and revealed that Griffith actually had surgery to remove skin cancer from her face, according to Daily Mail.
