While cancer rates are often higher in cell types with higher division rates, there are many other risk factors. The increased incidence of skin cancer is due largely to exposure to mutagenic ionising radiation from the sun, which is absorbed readily by the skin. Microwave radiation is more deeply penetrating. Although I believe it is unlikely to cause cancer.
