The deadliest form of skin cancer is on the rise in Marin County, which already has the highest rates of the disease in all of California.
The Marin Independent Journal notes that "sun worshipers" in the North Bay county may want to reconsider habits after learning that the cancer is the second-most-common cancer after prostate cancer for men, and has "increased significantly over the past decade."
Incidence of the disease has increased 200 percent since 2003, the newspaper reported.
Medical professionals say that "improved screening" may be behind the increase.
But Marin's demographics may also be at play: the county is mostly white, and white people are most at risk, the newspaper reported.
