Hugh Jackman has had his fifth cancerous skin growth removed in just over two years, the film and theater star said Monday.

“An example of what happens when you don’t use sunscreen,” Jackman, 47, tweeted, alongside a close-up of himself with a bandage over the bridge of his nose. “Basal cell. Mildest form of cancer. USE SUNSCREEN PLEASE !!” On his Instagram account, he posted the same photo and message, and urged people to get regular checkups.

The star, who plays the superhero Wolverine in the X-Men film franchise and appears in the upcoming sports drama “Eddie the Eagle,” was first diagnosed with skin cancer in November 2013, when he likewise posted a photo of himself with a bandaged nose. He tweeted then that his wife, actress and adoption advocate Deborra-Lee Furness, had “said to get the mark on my nose checked. Boy, was she right! I had a [basal] cell carcinoma,” he wrote, referring to a potentially disfiguring form of skin cancer. “Please don’t be foolish like me. Get yourself checked. And USE sunscreen!!!”

Since then, he has had two more growths removed from his nose and one from his shoulder.

The actor’s experiences led Jackman, a co-founder of the Pure Growth Group, to launch that company’s Pure Sun Defense children’s sunscreens last May.
