Skin Cancer Screening (PDQ®): Screening - Patient Information [NCI] - General Information About Skin Cancer
Skin cancer is a disease in which malignant (cancer) cells form in the tissues of the skin.The skin is the body's largest organ. It protects against heat, sunlight, injury, and infection. Skin also helps control body temperature and stores water, fat, and vitamin D. The skin has several layers, but the two main layers are the epidermis (top or outer layer) and the dermis (lower or inner layer). Skin cancer begins in the epidermis, which is made up of three kinds of cells:Squamous cells: Thin, flat cells that form the top layer of the epidermis. Cancer that forms in squamous cells is called squamous cell carcinoma.Basal cells: Round cells under the squamous cells. Cancer that forms in basal cells is called basal cell carcinoma.Melanocytes: Found in the lower part of the epidermis, these cells make melanin, the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes make more pigment and cause the skin to tan, or darken. Cancer that forms in melanocytes

Intraocular (Uveal) Melanoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Intraocular (Uveal) Melanoma
After intraocular melanoma has been diagnosed, tests are done to find out if cancer cells have spread to other parts of the body. The process used to find out if cancer has spread to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process:Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease in the organ or tissue that makes it.Liver function tests: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign the cancer has spread to the
Genetics of Skin Cancer (PDQ®): Genetics - Health Professional Information [NCI] - Psychosocial Issues in Familial Melanoma
This section reviews the literature examining risk reduction and early-detection behaviors in individuals with heightened risk of melanoma resulting from their family history of the disease and in individuals from hereditary families who have been tested for melanoma high-risk mutation status. The review also addresses risk perception and communication in individuals at heightened risk of melanoma.Motivation and Interest in Genetic Testing for Risk of MelanomaFew studies have examined motivation and interest in genetic testing for melanoma risk. In general, the findings include the following: High, but not universal interest in genetic testing.Articulated benefits of testing among those at heightened risk.A relative lack of examination of potential limitations of testing or reasons to forgo testing.In Australia, a qualitative study (N = 40) found that almost all participants with a strong family history of melanoma were interested in genetic testing.[1,2] Genetic testing was favored
