Is sun exposure is the only risk factor for melanoma that is avoidable?

Your best defense against melanoma and other skin cancers is to limit your exposure to ultraviolet (UV) light. Exposure to UV light is the only known preventable cause of melanoma.

Can you get melanoma without sun exposure?

Melanomas can also develop in areas of your body that have little or no exposure to the sun, such as the spaces between your toes and on your palms, soles, scalp or genitals. These are sometimes referred to as hidden melanomas because they occur in places most people wouldn’t think to check.

What is the main risk factor for melanoma?

Exposure to ultraviolet (UV) rays is a major risk factor for most melanomas. Sunlight is the main source of UV rays. Tanning beds and sun lamps are also sources of UV rays.

What is the most preventable risk factor for skin cancer?

The most important way to lower your risk of melanoma is to protect yourself from exposure to UV rays. Practice sun safety when you are outdoors.

How does sunlight contribute to the development of melanoma?

How can UV cause skin cancer? Too much UV radiation from the sun or sunbeds can damage the DNA in our skin cells. DNA tells our cells how to function. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.
