PD-1 inhibitors

Pembrolizumab (Keytruda) and nivolumab (Opdivo) are drugs that target PD-1, a protein on immune system cells called T cells that normally help keep these cells from attacking other cells in the body. By blocking PD-1, these drugs boost the immune response against melanoma cells.

Can immune system fight melanoma?

Melanoma is an aggressive cancer that can spread quickly. Immunotherapy is cancer treatment that enhances your immune system's ability to destroy melanoma cells and prevent their spread.

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.

Where does melanoma 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 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.
