Jackman said he went to the doctor after Deborra-Lee Furness, his wife of 17 years, said she didn't like the looks of a mark on the actor's nose, UsMagazine.com said.
"Deb said to get the mark on my nose checked. Boy, was she right! I had a basil cell carcinoma. Please don't be foolish like me. Get yourself checked. And USE sunscreen!!!" Jackman said in his Instagram posting, alongside a photo of his bandaged nose.
Jackman offered no other details about his condition or whether it will require further treatment.
