Skin Cancer Prevention (PDQ®): Prevention - Patient Information [NCI] - Skin Cancer Prevention
Avoiding risk factors and increasing protective factors may help prevent cancer.Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking, eating a healthy diet, and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer.Being exposed to ultraviolet radiation is a risk factor for skin cancer.Some studies suggest that being exposed to ultraviolet (UV) radiation and the sensitivity of a person's skin to UV radiation are risk factors for skin cancer. UV radiation is the name for the invisible rays that are part of the energy that comes from the sun. Sunlamps and tanning beds also give off UV radiation.Risk factors for nonmelanoma and melanoma cancers are not the same.Risk factors for nonmelanoma skin cancer:Being exposed to natural sunlight or artificial

Intraocular (Uveal) Melanoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview
There are different types of treatments for patients with intraocular melanoma. Different types of treatments are available for patients with intraocular melanoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.Five types of standard treatment are used:SurgerySurgery is the most common treatment for intraocular melanoma. The following types of surgery may be used:Resection: Surgery to remove the tumor and a small amount of healthy tissue around it.Enucleation: Surgery to remove the eye and part of

For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site.Stage I MelanomaTreatment of stage I melanoma may include the following: Surgery to remove the tumor and some of the normal tissue around it. Sometimes lymph node mapping and removal of lymph nodes is also done.A clinical trial of new

Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body.

Skin Cancer Prevention (PDQ®): Prevention - 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 layer). The epidermis is made up of 3 kinds of cells:Squamous cells are the thin, flat cells that make up most of the epidermis.Basal cells are the round cells under the squamous cells.Melanocytes are found throughout the lower part of the epidermis. They make melanin, the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes make more pigment, causing the skin to tan, or darken.The dermis contains blood and lymph vessels, hair follicles, and glands. Anatomy of the skin, showing the epidermis, dermis, and subcutaneous tissue. Melanocytes are in the layer of basal
