Skin grafting (taking skin from another part of the body to replace the skin that is removed) may be done to cover the wound caused by surgery.
Who gets adjuvant therapy for melanoma?
Adjuvant therapy is often recommended for patients with high-risk melanoma following surgery. High-risk melanoma includes patients with: Melanomas that are at least 2mm thick with ulceration (meaning the skin on the top of the melanoma has broken down); Melanomas over 4mm thick (with or without ulceration);
What is Alpha b2?
Interferon alfa-2b is an antiviral or antineoplastic drug. It is a recombinant form of the protein Interferon alpha-2 that was originally sequenced and produced recombinantly in E. coli in the laboratory of Charles Weissmann at the University of Zurich, in 1980.
How long has interferon been around?
Several different types of interferons are approved for use in humans. One was first approved for medical use in 1986.
Can Stage 4 melanoma be cured with immunotherapy?
Immunotherapy is used to treat advanced (stage 4) melanoma, and it’s sometimes offered to people with stage 3 melanoma as part of a clinical trial. Immunotherapy uses medicine to help the body’s immune system find and kill melanoma cells.
What is the most effective treatment for melanoma?
Surgery. Surgery to remove the tumor is the primary treatment of all stages of melanoma. A wide local excision is used to remove the melanoma and some of the normal tissue around it.
When is melanoma too late?
Melanoma is considered stage 4 when it has metastasized to lymph nodes in a part of the body far from the original tumor or if it has metastasized to internal organs like the lungs, liver, brain, bone or gastrointestinal tract. Symptoms of late-stage skin cancer depend on where the cancer is in the body.

What kills melanoma cells?
When melanoma cells are heated by laser beams, tiny bubbles form around the pigment proteins inside the cells. As these bubbles rapidly expand, they can physically destroy the cells. Although laser beams can also heat pigment in red blood cells, bubbles do not form and so there is no danger of harming healthy cells.
