When a person believes they have a possibly cancerous mole, there are several signs to watch out for, said Marks. If a mole is asymmetrical, has irregularly-edged borders, is more than one color, is larger than a pencil eraser or changes in any way over time, then it is likely to be melanoma, he said.
Marks recommended people check their bodies at least twice a year for any potentially cancerous moles.
“Melanoma is curable if found early,” said Marks.
