G'Day USA 2016 Black Tie Gala - InsideHugh Jackman has been treated for skin cancer again, the fourth time since 2013.

The Aussie actor shared a selfie on social media featuring a prominent bandage on his nose, along with a warning for fans. "An example of what happens when you don't use sunscreen," Jackman captioned the photo. "Basal cell. Mildest form of cancer. USE SUNSCREEN PLEASE !!"

If that message sounds familiar, it's because it's one that Jackman has repeated many times over the past few years, following his initial diagnosis of skin cancer in November 2013. The actor had his first treatment for basal-cell carcinoma that month, after his wife, Deborra-Lee Furness, noticed an unusual mark on Jackman's face and encouraged him to get it checked out; he underwent a second procedure in May 2014, and a third later that year, in October 2014. In addition to the procedures on his nose, he has also had cancerous cells removed from his shoulder.

As Jackman explained in an interview with People last year, his initial diagnosis was scary, though it's something familiar to his fellow Australians.

"It's always a bit of a shock just hearing the word 'cancer,'" the actor told People. "Being an Australian it's a very common thing. I never wore sunscreen growing up so I was a prime candidate for it."

Jackman added that his doctor told him he'd likely have many more recurrences throughout his lifetime, and the actor goes for checkups every three months to ensure he's healthy -- and get treated if he's not.

"It's the new normal for me," Jackman told People.

We're glad Jackman has his condition under control, and that he's encouraging his fans to protect themselves. Here's hoping he doesn't need to post any more bandaged selfies anytime soon.
