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.
