Hugh Jackman's Selfie Raises Awareness For Skin Cancer And Sunscreen

If it can happen to Wolverine, it can happen to you.

While most people know X-Men: Days Of Future Past as the latest installment in a fan-favorite film series, actor Hugh Jackman remembers the movie for something slightly different.

"I was filming X-Men: Days Of Future Past," Jackman told PEOPLE. "And my makeup artist said, 'You've got a little spot of blood, here on your nose' and I said 'Yeah, I know it was from a fight sequence and I knocked it somehow.' And trust me for 17 years I've played Wolverine and I've had more scraps and cuts... I'm very clumsy with those claws."

After consulting a doctor, Jackman discovered the truth behind the mark on his nose: it was basal cell carcinoma.

Basal cell carcinoma is the most frequently occurring type of the three forms of skin cancer. While it rarely spreads, or metastasizes, beyond the original tumor site, it can still be dangerous.

Anyone with a prolonged history of exposure in the sun is susceptible to developing basal cell carcinoma.

"Being an Australian it's a very common thing. I never wore sunscreen growing up so I was a prime candidate for it," Jackman told PEOPLE.

Avoiding sun exposure and using sunscreen are the best ways to avoid the disease. While Jackman co-founded a company that produces sun protection products for children, he felt that he needed to do more to warn the public about it.

Following his fifth basal cell carcinoma removal in less than three years, Jackman posted a selfie to Instagram. He also included a chilling warning to his fans and begged them to "please use sunscreen and get regular check-ups."

The selfie and message went viral.

Numerous fans wished him well on social media.

One fan had a personal reason to thank Jackman.
