Melanoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Recurrent Melanoma
Recurrent melanoma is cancer that has recurred (come back) after it has been treated. The cancer may come back in the area where it first started or in other parts of the body, such as the lungs or liver.

Melanoma Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information About Melanoma
Melanoma is a disease in which malignant (cancer) cells form in the skin cells called melanocytes (cells that color the skin). Melanocytes are found throughout the lower part of the epidermis. They produce melanin,the pigment that gives skin its natural color. When skin is exposed to the sun,melanocytes produce more pigment,causing the skin to tan,or darken. The skin is the body’s largest ..
Skin Cancer Prevention (PDQ®): Prevention - Patient Information [NCI] - What is prevention?
Cancerprevention is action taken to lower the chance of getting cancer. By preventing cancer,the number of new cases of cancer in a group or population is lowered. Hopefully,this will lower the number of deaths caused by cancer. To prevent new cancers from starting,scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a ...
Skin Cancer Screening (PDQ®): Screening - Health Professional Information [NCI] - About This PDQ Summary
Purpose of This SummaryThis PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about skin cancer screening. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.Reviewers and UpdatesThis summary is reviewed regularly and updated as necessary by the PDQ Screening and Prevention Editorial Board, which is editorially independent of the National Cancer Institute (NCI). The summary reflects an independent review of the literature and does not represent a policy statement of NCI or the National Institutes of Health (NIH). Board members review recently published articles each month to determine whether an article should:be discussed at a meeting,be cited with text, orreplace or update an existing article that is already cited.Changes to the summaries are made through a consensus process in which
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
