Spending too much time in the sun gives you wrinkles and makes you more likely to get skin cancer.
Skin Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Skin Cancer
After nonmelanoma skin cancer has been diagnosed, tests are done to find out if cancer cells have spread within the skin or to other parts of the body. The process used to find out if cancer has spread within the skin or 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:CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of
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
Skin Cancer Prevention (PDQ®): Prevention - Health Professional Information [NCI] - Changes to This Summary (07 / 25 / 2013)
The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.Description of the EvidenceAdded text to state that the current evidence indicates that sunscreen application as practiced in the general population shows no clear association with reduced risk of melanocytic nevi or melanoma.This summary is written and maintained by the PDQ Screening and Prevention Editorial Board, which is editorially independent of NCI. The summary reflects an independent review of the literature and does not represent a policy statement of NCI or NIH.

Skin Cancer Screening (PDQ®): Screening - Patient Information [NCI] - Risks of Skin Cancer Screening
Screening tests have risks.Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.The risks of skin cancer screening tests include the following: Finding skin cancer does not always improve health or help you live longer. Screening may not improve your health or help you live longer if you have advanced skin cancer.Some cancers never cause symptoms or become life-threatening, but if found by a screening test, the cancer may be treated. Treatments for cancer may have serious side effects.False-negative test results can occur.Screening test results may appear to be normal even though cancer is present. A person who receives a false-negative test result (one that shows there is no cancer when there really is) may delay getting medical
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
Skin Cancer Treatment (PDQ®): Treatment - 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 (upper or outer layer) and the dermis (lower or inner ...

Intraocular (Uveal) Melanoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Classification and Stage Information for Intraocular (Uveal) Melanoma
Tumor SizeUveal melanoma most often assumes a nodular or dome-shaped configuration, but occasionally tumors can be flat or diffuse and involve extensive areas of the uvea with little elevation. Tumor size classifications according to boundary lines used in a Collaborative Ocular Melanoma Study (COMS) are as follows: Small: Range from 1.0 mm to 3.0 mm in apical height and largest basal diameter of 5.0 to 16.0 mm. Medium: Range from 3.1 to 8.0 mm in apical height and a basal diameter of not more than 16.0 mm. Large: Greater than 8.0 mm in apical height or a basal diameter more than 16.0 mm, when the apical height is at least 2.0 mm.Although most ocular melanomas have a raised configuration, about 5% grow in a diffuse pattern that also may have prognostic significance. The tumors have a horizontal, flat-growth pattern, with the thickness measuring approximately 20% or less than the greatest basal dimension. This uncommon variant of uveal
