What is melanoma and what are the early signs of the skin cancer?

What is melanoma? Melanoma is a form of skin cancer, which develops from cells called melanocytes. Melanocytes are skin cells that produce melanin, the pigment that controls the colour of your skin. Melanin protects your skin from UV radiation, which is why people with lighter skin who have less melanin are more susceptible to sunburn. While melanoma is typically thought of as a cancer of the skin, it can also occur elsewhere on the body. Cutaneous melanoma is the melanoma of the skin, as explained by the Melanoma Research Foundation. Mucosal melanoma occurs on mucous membranes of the body such as the nasal passage or throat, while ocular melanoma is a rare form of the disease that occurs in the eyes What are the causes? The majority of cases of the skin cancer are caused from excessive exposure to ultraviolet rays. Too much time spent in the sun without adequate protection can increase risk of melanoma. Using indoor tanning beds has also been linked to the development of skin cancer, as they can emit stronger UV rays than the sunWhat are the signs? One of the most widely known signs of melanoma is if you notice a new mole on your body or if you’ve spotted that an old mole has changed in colour, shape or size. The NHS suggests speaking to a doctor as soon as possible if you become aware of any changes to moles on your body. In addition to moles that have enlarged, changed shape or changed colour, you should also keep an eye out for moles that have become itchy or sore or moles that have begun bleeding. Moles can appear anywhere on the body, although they’re more likely to appear on men’s backs and women’s legs, as stated by the American Cancer Society. Is any sun exposure safe? While the vitamin D emitted from the sun is extremely beneficial for your overall wellbeing, tanning is apparently always detrimental, "A tan is a response to DNA damage, whether you get it on the beach, on a sunbed, or through incidental exposure. "Tans are caused by harmful UV radiation from the sun, and if you have one, you've sustained skin cell damage."
