This minimizes harm to healthy tissue. The tissue is then biopsied to determine if all of the tumor was removed. In Mohs Micrographic Surgery, a surgeon sequentially removes layers of the tumor and checks them with a microscope until the tissue area is completely tumor-free. This treatment has the highest cure rate and saves healthy tissue. But the best way to defeat skin cancer is to avoid it.

It takes 10-20 years for the damage to manifest, so we're expecting to see more cases. That is unless Americans get the message the way many Australians have. Studies indicate that melanomas rates in Australian women are now dropping. Other studies indicate that at the beach as many as 50 minutes elapse before the last member of a family applies their sunscreen. Dermatologists recommend sun block be applied 20 minutes before going outside, because the preparation needs sufficient time to activate.
