What type of skin cancer is caused by over-exposure to ultraviolet radiation?

The type of skin cancer primarily caused by over-exposure to ultraviolet (UV) radiation is melanoma. Melanoma is known for its ability to develop from the pigment-producing cells called melanocytes and is often linked to excessive sun exposure, particularly intermittent intense exposure leading to sunburn. While other forms of skin cancer, such as basal cell carcinoma and squamous cell carcinoma, are also associated with UV exposure, melanoma is the most aggressive and serious type of skin cancer that arises from this kind of environmental factor.

Carcinoma in situ refers to a group of abnormal cells that remain in the place where they first formed and have not spread. While they can be precursors to other cancers, they are not classified directly as a type of skin cancer that results from UV exposure in the same context as melanoma.

Understanding the role of UV radiation in skin cancer development highlights the importance of preventive measures, such as sunscreen use and protective clothing, to reduce the risk of melanoma and other skin cancers.
