Skin Cancer Stages
once the cancer is found in
your skin, it is necessary to find its stage. In general, the stage of melanoma is measured from the size of
the tumor and the presence of cancerous cells in any lymph nodes or other parts of the body: lungs, brain,
spinal cord, liver or bone. Your oncologist can use the result of the biopsy to determine the stage of the
Situ – also called
stage 0, this 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 into other areas of your body. Your survival chance is less than
- Stage II
– stage 2 is considered as a
high risk melanoma; the cancer can spread to other areas of the body, and survival chance is about 40-85%.
- Stage III
– at stage 3, the cancer
is more aggressive; the risk of regional metastasis is higher; survival chance is
estimated at 25-60%.
- Stage IV
– your survival chance has
decreased considerably to 9-15%;
the cancer is often associated with distant metastases.
- Stage IV – at stage 4, the tumor has become more aggressive;
the cancer has spread beyond your skin to other organs, such as your lungs, liver and bone. survival chance
has decreased considerably.
Squamous cell carcinoma - In general, squamous cell carcinoma develops in three
- Stage I – at stage 1, the cancer remains superficially in
the tissue where it originates; chances of surviving is very high.
- Stage II – a stage 2, the squamous cell carcinoma has
infiltrated deeply into the tissue of the skin, and it is associated with a high risk of recurrence in
cases of limited surgery. Loco-regional invasion may also occur, particularly in the pelvis. In addition,
the cancer may have affected the bone tissue surrounding the tumor.
- Stage III - at this stage, the cancer has become more
aggressive with high risk of lymph node metastases; survival chance decreases significantly. Without a
prompt and effective treatment, the cancer can travel though the bloodstream to form other tumor in
surrounding or distant areas from the tumor: lungs, liver, brain or bone.
