its related to cell cycle physiology Most chemotherapy drugs kills cell while they are dividing. Cancer cells divide faster afterwards normal cell. That is why the chemo kills cancer cell more than normal cell. Other cells that divide efficient are immune cells, blood cell, hair cell and the cells surrounded by the lining of the stomach. This is why the side effects of may chemo agents are immunosuppression, anemia, pelt loss and mucositis/stomatitis.
Different chemo agents stop the cell cycle in different ways. Some are antimetabolites and block the use of vitamin indispensable for cell division. Some bind to the tubules and don't allow the cell to divide. The mechanisms rise and fall but the end result is like. Cell death.
by bloodshed the defective cells
these drugs inhibit the further divisions of the tumour cell by blocking out the cell division piece of equipment.
First you have to take that chemotherapy poisons the body. Cancer cells by their outlook are less resistant to poisoning than usual cells. The trick is to poison the body satisfactory to kill the cancer cell without butchery the host - look at the affects of chemotherapy and you can see how bad it is for you. Cancer, logically, is worse.
It kills nippy growing cells.
