What Is Chemotherapy?
One of the methods used to treat cancer is called chemotherapy. The chemotherapy process uses strong drugs in order to kill cancer cells. Compared to radiotherapy or surgery, which are both local treatments, chemotherapy is a systemic treatment, which means it can treat cancer almost anywhere in the body.
Strong drugs are needed since cancer cells multiply faster compared to other cells in the body, so the drugs used to kill them off need to be able to keep up with how fast the cancer cells are dividing.
