What are the final stages of melanoma cancer?

Melanoma can spread to parts of your body far away from where the cancer started. This is called advanced, metastatic, or stage IV melanoma. It can move to your lungs, liver, brain, bones, digestive system, and lymph nodes. Most people find their skin cancer early, before it has spread.

Is melanoma genetic?

Few people inherit melanoma genes

About 10% of melanomas are caused by a gene mutation (change) that passes from one generation to the next. Most people get melanoma for other reasons. The sun, tanning beds, and tanning lamps give off ultraviolet (UV) rays. These rays are known to damage our skin.

Why is melanoma so aggressive?

“The tumor absorbs a high concentration of TGF-beta, which stimulates melanoma cells and renders them aggressive.”

Is melanoma a death sentence?

Metastatic melanoma was once almost a death sentence, with a median survival of less than a year. Now, some patients are living for years, with a few out at more than 10 years. Clinicians are now talking about a ‘functional cure’ in the patients who respond to therapy.

Where does melanoma usually spread to first?

Normally, the first place a melanoma tumor metastasizes to is the lymph nodes, by literally draining melanoma cells into the lymphatic fluid, which carries the melanoma cells through the lymphatic channels to the nearest lymph node basin.

Is melanoma always malignant?

While malignant, these are unlikely to spread to other parts of the body if treated early. They may be locally disfiguring if not treated early. A small but significant number of skin cancers are malignant melanomas. Malignant melanoma is a highly aggressive cancer that tends to spread to other parts of the body.
