What could be a cause of melanoma?

Exposure to ultraviolet (UV) radiation from the sun or tanning beds. UV radiation can damage the DNA in skin cells, leading to the development of melanoma.

A family history of melanoma. People with a family history of melanoma are more likely to develop the disease. This is because they may inherit genes that make them more susceptible to the effects of UV radiation.

Fair skin. People with fair skin are more likely to develop melanoma than people with darker skin. This is because fair skin has less melanin, which is a pigment that helps to protect the skin from the sun's UV radiation.

A history of sunburns. People who have had multiple sunburns are more likely to develop melanoma. This is because sunburns can damage the DNA in skin cells, leading to the development of melanoma.

A weakened immune system. People with a weakened immune system are more likely to develop melanoma. This is because the immune system helps to protect the body from cancer cells. People with weakened immune systems may not be able to fight off melanoma cells as effectively as people with healthy immune systems.

Being male. Men are more likely to develop melanoma than women. This is because men are more likely to have fair skin, a history of sunburns, and a weakened immune system.
