Melanoma is a type of skin cancer that develops when melanocytes (the cells that give the skin its tan or brown color) start to grow out of control. Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can then spread to other areas of the body.
Which type of skin cancer is the most dangerous?
Nov 15, 2021 · Most skin cancers are caused by exposure to ultraviolet (UV) light. When you don’t protect your skin, UV rays from sunlight or tanning beds can damage your skin’s DNA. When the DNA is altered, it can’t properly control skin cell growth, leading to cancer.
What are the early stages of skin cancer?
Skin cancer is the out-of-control growth of abnormal cells in the epidermis, the outermost skin layer, caused by unrepaired DNA damage that triggers mutations. These mutations lead the skin cells to multiply rapidly and form malignant tumors. The main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), melanoma and Merkel cell carcinoma (MCC).

When melanoma occurs in people with darker skin, it's more likely to occur in a hidden area.
What happens when you have melanoma?
Melanoma occurs when something goes wrong in the melanin-producing cells (melanocytes) that give color to your skin. Normally, skin cells develop in a controlled and orderly way — healthy new cells push older cells toward your skin's surface, where they die and eventually fall off.

How to detect Merkel cell carcinoma?
Clinical features of Merkel cell carcinoma led to the development of the AEIOU method to help people with early detection: 1 Asymptomatic —If there is a lack of tenderness in the nodule, Merkel cell carcinoma may be suspected. 2 Expanding rapidly —If the nodule grows rapidly in less than three months, it could mean that it is a case of Merkel cell carcinoma. 3 Immunosuppression —A weakened immune system can mean a person is more at risk for developing Merkel cell carcinoma. 4 Older age —Adults over 50 are more susceptible to this type of cancer. 5 UV exposure —Because exposure to the sun can increase the risk of developing this type of skin cancer, monitoring how much sun a person gets is a good way to determine their risk level when growth appears.
