Previous research in mice has found that retinol and related compounds can decrease the size of tumors and prolong survival in melanoma.

But the best way to prevent skin cancer is to use sun protection and limit time spent in direct sun, Day stressed. "You need to be sun-smart," she said.

Dr. Robert Graham, an internist at Lenox Hill Hospital in New York City, added that based on these findings, "there is some promise of v
