UVB is the form of UV irradiation most responsible for sunburn and has strong links to malignant melanoma and basal cell carcinoma risk (types of skin cancer).

cells grow out of control and become a cancerous and life-threatening melanoma. Melanoma accounts for 5% of all skin cancers and it results in most of the skin cancer deaths. At first‚ melanoma cells are found in the epidermis and top layers of the dermis.
