What is melanoma?
Melanoma is a disease of the skin in which cancer cells are found in the melanocytes, the cells that produce color in the skin or pigment known as melanin. Melanoma usually occurs in adults, but it may occasionally be found in children and adolescents. Melanoma may also be called cutaneous melanoma or malignant melanoma. Melanoma is the rarest, but most virulent, form of skin cancer.
Melanoma is a more serious type of cancer than the more common basal cell cancer, or squamous cell cancer. Although the incidence of melanoma is lower than other types of skin cancer, it has the highest death rate and is responsible for a majority of all deaths from skin cancer.
What are the risk factors for melanoma?
Persons with the following characteristics may be at an increased risk for melanoma:
- blond or red hair
- blue eyes
- fair complexion
- family history of melanoma
- a changed or changing mole
- many ordinary moles (more than 50)
- many freckles
- an immunosuppressive disorder
- dysplastic nevi
- sun exposure The amount of time spent unprotected in the sun directly affects your risk of skin cancer.
- inability to tan
Dark-brown or black skin is not a guarantee against melanoma. African-Americans can develop this cancer, especially on the palms of the hands, soles of the feet, under nails, or in the mouth.
