An inexpensive vitamin can help reduce the occurrence of common skin cancers in people prone to that disease, researchers reported on Wednesday.
In a clinical trial, people who took two pills a day of nicotinamide, a form of vitamin B3 available as a nutritional supplement, had a 23 percent lower risk of developing non-melanoma skin cancer than those who took placebo pills.
“It’s safe, it’s almost obscenely inexpensive and it’s widely available,” Dr. Diona Damian, the lead investigator of the study, said in a news conference organized by the American Society of Clinical Oncology, who said the findings could be put into practice right away.
“This one’s ready to go straight into the clinic,” said Dr. Damian, a dermatology professor at the University of Sydney in Australia. However, she said the vitamin should be used only by people who get frequent skin cancers, not by everyone.
