What is mucosal cancer?
Mucosal melanoma is a rare type of melanoma that occurs on mucosal surfaces. Mucous membranes are moist surfaces that line cavities within the body. This means that mucosal melanoma can be found in the respiratory tract, gastrointestinal tract or genitourinary tract.
How long can you live with mucosal melanoma?
Mucosal melanoma is a disease with a very poor prognosis and most patients will develop incurable metastatic disease, irrespective of surgical excision. 5-year survival rates may be as low as 14%, compared with 90% for cutaneous melanoma [4,5] when all cases, regardless of stage are combined.
What are the symptoms of melanoma that has spread?
If your melanoma has spread to other areas, you may have:
- Hardened lumps under your skin.

How do you stage mucosal melanoma?
This clinical staging system is as follows:
- Stage 1: The disease remains localized.
- Stage 2: Nodes in the region or area around the disease become involved.
- Stage 3: The disease becomes metastatic and involves distant areas and organs.

How long does it take for melanoma to spread to organs?
How fast does melanoma spread and grow to local lymph nodes and other organs? “Melanoma can grow extremely quickly and can become life-threatening in as little as six weeks,” noted Dr. Duncanson. “If left untreated, melanoma begins to spread, advancing its stage and worsening the prognosis.”
