Skin cancer occurs when DNA from some healthy cells of the skin undergo a mutation that causes them to multiply anarchically. In certain type of skin cancer, mainly basal cell carcinoma, the mutation is caused by damage to a gene called PTC by ultraviolet (UV) radiation from sunlight and/or commercial tanning lamps and tanning beds.
Unlike many types of cancer, the causes of skin cancer are more or less known. Numerous studies have demonstrated that basal cell carcinoma, squamous cell carcinoma and melanoma are associated with significant exposure to sunlight. The risk is even higher when the exposure starts in the early years of life. That is, prolonged and continuous exposure to sunlight in childhood is the main factor that can cause skin cancer later in life.
Although exposure to ultraviolet rays from the sun is the main cause of skin cancer, artificial sources of ultraviolet radiation (tanning lamps and tanning beds) are also suspected in the development of the disease. It is shown prolonged skin contact with certain chemicals can increase the risk of skin cancer.
This risk is higher if you have fair skin, blond or red hair, blue or green eyes, freckles and moles. In addition, if you tan easily, you’re more likely to develop cancer of the skin because your skin is less pigmented and less protected from the sun.
