First - "chemotherapy" is a basic term applied to over 75 specific medicines which each and every have exceptional mechanisms of action. There are lots of chemotherapy medicinal drugs that interfere with the mitotic cycle and kill dividing cells - both ordinary cells and cancer cells. The hope is that more melanoma cells will be damaged and killed than average cells. That's what makes it so complex. However there are newer, far more steeply-priced, chemotherapy medicinal drugs coming out in recent years that inhibit tumor blood vessel formation or impact cancers in other approaches. The phrase chemotherapy simply manner a chemical agent used to treat malignant illnesses - just like the phrase "antibiotic" means any of the various chemical agents used to deal with infectious ailments triggered via microorganisms.

Chemo drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division. If the cancer cells are unable to divide, they die. The faster that cancer cells divide, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce cell suicide (self-death or apoptosis).
