The increasing knowledge that scientists are gaining about the basics of our biology are allowing them to gain the upper hand in the war against cancer.  is the most deadly of skin cancers because it metastasizes so well. 

Scientists have discovered the mechanism that allows it to do so and to put a stop to it. When the immune system attacks melanoma, it evades being destroyed because it has a surface protein CD47 which tells the immune cells not to eat the cancer cells. By blocking CD47 and another protein, CD271, scientists have stopped melanoma from metastasizing.
