(CNN) - John McCain had a mole-like growth removed Monday from his temple, the McCain campaign said.
Doctors did not think the growth was cause for concern, but it was removed as a precautionary measure, the campaign said. It was noticed during McCain's standard three-month checkup and a biopsy on the mole was planned.
McCain was wearing a bandage on his face as a result of the procedure, but has since removed it.
McCain has had four malignant melanomas removed in the past. Three of them - on his left shoulder, left arm and left nasal wall - were limited to the top skin layer and were not invasive. They were removed in 1993, 2000 and 2002, and all were declared Stage 0, of little long-term concern.
But a fourth melanoma proved to be invasive and was removed from his left lower temple in 2000. He has since been cancer-free.
UPDATE: Speaking with reporters Monday, McCain said he is confident the removed mole is nothing major.
"As I do every three months, [I] visited my dermatologist this morning, she said I was doing fine, took a small little nick from my cheek, as she does regularly, and that will be biopsied, just to make sure that everything is fine," he said.
"But I want to again urge all Americans to wear sunscreen particularly this summer, stay out of the sun as much as possible. Wear sunscreen, and if you ever have any slight discoloration, please go to your dermatologist or your doctor, and get it checked up on. Melenoma is a preventable occurrence. It really is," he also said.
