How Does Chemotherapy Work?


Chemotherapy is designed to kill cancer cells. Chemotherapy can be administered through a vein, injected into a body cavity, or delivered orally in the form of a pill, depending on which drug is used.

Some cancer cells grow slowly while others grow rapidly. As a result, different types of chemotherapy drugs target the growth patterns of specific types of cancer cells. Each drug has a different way of working and is effective at a specific time in the life cycle of the cell it targets. Your doctor will determine the chemotherapy drug that is right for you.
