Melanoma
Melanoma
is a malignant tumor of melanocytes which are found predominantly in
skin but also in the bowel and the eye (see uveal melanoma). It is one
of the rarer types of skin cancer but causes the majority of skin cancer
related deaths. Malignant melanoma is a serious type of skin cancer.
It is due to uncontrolled growth of pigment cells, called melanocytes.
Despite many years of intensive laboratory and clinical research, the
sole effective cure is surgical resection of the primary tumor before
it achieves a Breslow thickness greater than 1 mm.
Around
160,000 new cases of melanoma are diagnosed worldwide each year, and
it is more frequent in males and caucasians. It is more common in caucasian
populations living in sunny climates than other groups. According to
a WHO Report about 48,000 melanoma related deaths occur worldwide per
year.
Malignant
melanoma accounts for 75 percent of all deaths associated with skin
cancer.
The treatment includes surgical removal
of the tumor; adjuvant treatment; chemo- and immunotherapy, or radiation
therapy.
