'Idling' cancer cells may return

About half of all melanomas have mutations in the BRAF gene that accelerate tumor cell growth and spread. While most patients benefit from targeted anti-BRAF therapy, resistance to treatment and tumor progression is almost ...

Melanoma i/ˌmɛləˈnoʊmə/ (from Greek μέλας - melas, "dark") is a malignant tumor of melanocytes. Melanocytes are cells that produce the dark pigment, melanin, which is responsible for the color of skin. They predominantly occur in skin, but are also found in other parts of the body, including the bowel and the eye (see uveal melanoma). Melanoma can occur in any part of the body that contains melanocytes.

Melanoma is less common than other skin cancers. However, it is much more dangerous and causes the majority (75%) of deaths related to skin cancer. Worldwide, doctors diagnose about 160,000 new cases of melanoma yearly. The diagnosis is more frequent in women than in men and is particularly common among Caucasians living in sunny climates, with high rates of incidence in Australia, New Zealand, North America, Latin America, and northern Europe. According to a WHO report, about 48,000 melanoma related deaths occur worldwide per year.

The treatment includes surgical removal of the tumor, adjuvant treatment, chemo- and immunotherapy, or radiation therapy. The chance of a cure is greatest when the tumor is discovered while it is still small and thin, and can be entirely removed surgically.
