>Paradoxically while sun exposure (UVb) increases the risk of melanoma and non-melanoma skin
cancer, sun exposure reduces the overall risk of dying from cancer. (396) in 1937, Peller and
Stephenson reported that soldiers of the U.S. Navy, intensively exposed to open air, sun rays,
and salt water, had 8-fold higher frequency of skin cancer (melanoma) and lip cancer, but the
death rate among these cases of cancer was 3-fold lower than expected. In addition, they
reported a 44% lower incidence of other cancer-related deaths. (397) In patients with melanoma sun exposure is strongly negatively associated with death from melanoma. (398) An
Italian study reported that sunbathing holidays after a diagnosis of melanoma were related to
reduced rates of relapses (HR=0.3, 95% CI=0.1-0.9). (399) In the MISS study (Melanoma in
Southern Sweden), there was a dose dependent increase in the risk of death with lower sun
exposure, with a 40% higher risk of cancer-related death in the group with low sun exposure
[sHR=1.4, 95% CI=1.04-1.6] as compared to those with greatest sun exposure. (396) It should be
noted that Sunscreen users in Sweden have been reported to be at an 80% increased risk of
melanoma. (OR=1.8, 95%CI=1.1-2.9). (400) A plausible explanation of this increased melanoma
risk might be that the application of a sunscreen inhibits the redness of the skin but allows
prolonged UV exposure.
