the cancer is found in your skin, it is necessary to determine its stage. In general, the stage of melanoma is
determined according to its size and its extension – the spread of cancerous cells into lymph nodes or other
parts of the body: lungs, brain, liver, bone, and spinal cord.
- Melanomain Situ
– also called stage
0, melanoma in situ is the genesis of the cancer cells; your five-year
survival chance is about 99.9%.
- Stage I
– at this stage, the
melanoma is invasive; although it
is well localized, the cancer can spread to other areas of your body. Your five-year survival chance is
less than 95%.
- Stage II
– stage 2 is considered as a
high risk melanoma; the cancer can spread into other areas of your body, and your 5-year survival rate is
- Stage III
– at stage 3, the cancer
is more aggressive; the risk of regional metastasis increases. Your chance to survive
5 years after the diagnosis is estimated at 25-60%.
- Stage IV A
– your survival chance has
decreased considerably to 9-15%;
the cancer is often associated with distant metastasis such
as distant skin metastasis and lung metastasis
- Stage IV B – at this stage, the tumor has become more
aggressive; the cancer has spread beyond your skin to other organs, such as lungs, liver and bone. Your
five-year survival chance has decreased considerably.
