What skin color is most likely to get skin cancer?

People with light skin are much more likely to have their skin damaged by UV rays (and to get skin cancer), but darker-skinned people, including people of any ethnicity, can also be affected. For some people, the skin tans when it absorbs UV rays.

At what age does skin cancer typically occur?

Age. Most basal cell and squamous cell carcinomas typically appear after age 50. However, in recent years, the number of skin cancers in people age 65 and older has increased dramatically. This may be due to better screening and patient tracking efforts in skin cancer.

What will happen if melanin decreases?

Less melanin means less protection from the sun’s rays. This raises the risk of wrinkles, uneven texture, and discoloration. Increased risk of skin cancer. The high risk of sun damage also increases your chances of developing skin cancer.

Does more melanin means darker skin?
