Although almost all cases of melanoma are related to the effects of ultraviolet light on the skin, the exact cause is still unknown.
Sunlight is the main source of ultraviolet which can affect the skin. In most cases, melanoma is thought to be caused by sun exposure. But know that not all melanomas are related to ultraviolet light exposure, because this condition can still appear on areas of the skin that are rarely exposed to sunlight.
There are two main types of ultraviolet light that can penetrate the ozone layer in the Earth’s atmosphere, namely ultraviolet A (UVA) and ultraviolet B (UVB). If you are too long and repeatedly exposed to UVA and UVB, the skin will experience damage and make it more susceptible to skin cancer (including melanoma).
All the factors below make your skin more sensitive to the adverse effects of sunlight. Factors that can increase the risk of developing melanoma are:
1. Have a lot of moles.
2. Has many spots on the skin.
3. There is an area of skin that has been burned or after undergoing treatment with radiotherapy.
4. Pale skin that is flammable and the skin is difficult to turn black.
5. Have blue eyes and reddish or blond hair.
6. Aging age.
7. Experiencing conditions that reduce the immune system, such as HIV.
8. Medications that reduce the immune system (immunosuppression), usually this type of drug is consumed after an organ transplant.
9. Have been diagnosed with skin cancer.
10. There are family members who have melanoma or other types of skin cancer.
11. Exposure to chemical compounds in the form of arsenic compounds or creosote pepticides.
