What Is Melanoma

MelanomaMelanoma is a cancer of pigment producing cells called melanocytes. Most melanomas originate from the skin, though they can also arise from other parts of the body containing melanocytes, including the eyes, brain or spinal cord, or mucous membranes. Some melanomas are first detected when they spread to other parts of the body, without a documented primary tumor.

Melanoma of the skin is one of the most common cancers in the United States - among the top 10 causes of new cancer cases. While the overall five-year survival rate for people diagnosed with melanoma is high at 92 percent compared to 66 percent for all other cancers, the survival rate decreases dramatically once melanoma spreads to other parts of the body. Very early stage (localized, Stage 0 or I) melanoma is greater than 90 percent curable with surgery, while patients with disseminated Stage IV melanoma have a median life expectancy of less than one year.

The ability to spread widely to other parts of the body is a unique characteristic of melanoma that the other more common skin cancers, basal cell carcinoma and squamous cell carcinoma, do not possess. This characteristic makes melanoma the deadliest of all skin cancers: melanoma accounts for only four percent of skin cancers, but 80 percent of skin cancer-related deaths.

Facts About Melanoma

  • In the United States each year, more than 76,000 Americans are diagnosed with melanoma - one person every eight minutes.
  • More than 9,480 Americans die of melanoma - one person every hour.
  • Almost twice as many men in the US die from melanoma than women.
  • Despite tremendous advancements in medicine, the melanoma death rate has remained static over the past 30 years while the incidence is rising.

Nine U.S. Food and Drug Administration approved therapies for metastatic melanoma currently exist, but most benefit only a subset of patients. More effective options for prevention, diagnosis, prognosis, and treatment are urgently needed.

Advances in Treatments

New treatments under development, including immunotherapies and molecularly targeted therapies, have produced dramatic responses in some patients with advanced disease. Even though some tumor regressions have proved to be transient, these results provide proof-of-principle for moving forward. Decades of research in melanoma have translated into significant scientific and clinical advances over the past few years and have generated much excitement in the scientific community and among patients and advocates. Investigators are finding ways to improve upon these results to combat this deadly disease.
