Basal-cell carcinoma (BCC), also known as basal-cell cancer, basalioma[7] or rodent ulcer, [8] is the most common type of skin cancer. [2] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it. [1] It may also present as a raised area with ulceration. [1]

Most chronic (long-lasting) pain is caused by the illness and most acute (short-term) pain is caused by treatment or ...
Squamous-cell carcinoma. Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts.
Melanoma is the most dangerous type of skin cancer; it develops from the melanin -producing cells known as melanocytes. [ 1 ] It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma).

Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]
Kaposi's sarcoma (KS) is a type of cancer that can form masses on the skin, in lymph nodes, in the mouth, or in other organs. [ 4 ][ 6 ] The skin lesions are usually painless, purple and may be flat or raised. [ 6 ][ 8 ] Lesions can occur singly, multiply in a limited area, or may be widespread.
