In addition, due to cytotoxic therapy doctors have learned to successfully treat systemic tumors such as leukemia and other blood diseases.

The mechanism of action

The basis of most chemotherapeutic drugs is their ability to stop the most important biological processes in tumor cells. They act on cells in various stages of the cell cycle, stopping the process of division and growth.

Particularly vulnerable organs and tissues, where cells divide rapidly: the hair follicles of the skin, bone marrow, gastro-intestinal tract.
