But Melanoma is preventable. Exposure to the sun causes 90% of all skin cancers. Limiting mid-day exposure or covering up is the best way to avoid it.
Sunscreen is not a cure, since it only protects against UVB not against UVA. Men are more likely to work outside and have the highest exposure to the sun’s harmful rays than women. Tanning is not healthy, because UV rays fry inner layers of the skin, which causes the body to release melanin pigment to darken the outer layers as a protective measure.
