No form of melanoma is believed to be related to asbestos.
Almost all patients survive stage Ia malignant melanoma, and the suvivorship for stage I overall is more than 90%.
Melanoma is not cured unless it is diagnosed at a stage when it can be isolated and removed surgically.
Some patients, such as those with IIb or stage III melanoma, are at high risk for the development of recurrence after treatment.
The stages of melanoma. The stage of a melanoma describes how deeply it has grown into the skin, and whether it has spread. In the UK 8 out of 10 melanomas (80%).
These stages are subdivided on the basis of penetration. Stage Ia is 0.75 mm or less (1 mm = 0.04 in), and Stage Ib is 0.75-1.5 mm penetration. Stage IIa is 1.5-4.0 mm and Stage IIb is over 4.0 mm or into the subcutaneous fat.
Survival drops in stage IIa to about 65% at five years and is worse yet for stage IIb at slightly over 50%.
Though radiation therapy has a minimal role in the primary treatment of malignant melanoma, for patients who have metastatic disease, radiation may be helpful.
For stage IV patients, or those that are treated and then develop recurrence at distant sites, chemotherapy or immunotherapy is planned.
Stage IV is dependant upon how far from the primary site the cancer was found. Since it is melanoma, it harder to find the primary site, since this cancer affects skin cells. Stage 0 Carcinoma in situ (early cancer that is present only in the layer of cells in which it began). Stage I, Stage II, and Stage III Higher numbers indicate more extensive disease: greater tumor size, and/or spread of the cancer to nearby lymph nodes and/or organs adjacent to the primary tumor. Stage IV The cancer has spread to another organ
Malignant melanoma
Melanoma is a non-communicable disease and is not transmitted as an infectious disease is. It is the spreading of the disease.
