BackgroundIncidence and mortalityThere are three main types of skin cancer:Basal cell carcinoma (BCC).Squamous cell carcinoma (SCC), which together with BCC is referred to as nonmelanoma skin cancer (NMSC).Melanoma.BCC and SCC are the most common forms of skin cancer but have substantially better prognoses than the less common, generally more aggressive, melanoma.NMSC is the most commonly occurring cancer in the United States. Its incidence appears to be increasing in some, but not all, areas of the country. Overall U.S. incidence rates have likely been increasing for a number of years. At least some of this increase may be attributable to increasing skin cancer awareness and resulting increasing investigation and biopsy of skin lesions. The total number and incidence rate of NMSCs cannot be estimated precisely because reporting to cancer registries is not required. However, based on extrapolation of Medicare fee-for-service data to the U.S.
Stage 0 melanoma is defined by the American Joint Committee on Cancer's TNM classification system:Tis, N0, M0Patients with stage 0 disease may be treated by excision with minimal, but microscopically free, margins. Current Clinical TrialsCheck for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage 0 melanoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.General information about clinical trials is also available from the NCI Web site.References: Melanoma of the skin.

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 ...
There are different types of treatment for patients with metastatic squamous neck cancer with occult primary. Different types of treatment are available for patients with metastatic squamous neck cancer with occult primary. 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.Two types of standard treatment are used:Surgery Surgery may include neck dissection. There are different types of neck dissection, based on the amount of tissue that is removed. Radical neck dissection: Surgery to remove tissues
