Skin Cancer of Scalp, Neck Deadlier

Melanoma is the rarest, deadliest form of skin cancer, but new research shows that a tumor's location is an indicator of survival chances. An analysis of 50,000 cases over a decade shows patients with lesions on the scalp and neck died twice as quickly as patients with lesions elsewhere, reports Time.

"The results really did surprise us," said the lead researcher. "There has been a lot of controversy over whether all head and neck melanomas had worse survival—and this study shows a large difference in survival for scalp and neck tumors." (More melanoma stories.)
