People who eat citrus are ar higher risk of developing a certain skin cancer, according to a recent study, though whether the fruit actually caused the disease was not examined. The potential link between citrus consumption and malignant melanoma applied to both women and men.

Confusingly, earlier studies linked eating the peel of citrus to reduced risk of another skin cancer - squamous cell carcinoma. Life is complicated.

The new melanoma results, from an observational study that may not reflect the whole U.S. population, should be interpreted with caution, stated senior author Dr. Abrar Qureshi of the Warren Alpert Medical School of Brown University and Rhode Island Hospital, who worked on the study with the Channing Division of Network Medicine at Brigham and Women's Hospital in Boston.
