Question

How does chemotherapy work to treat cancer?

Answer 1

Chemotherapy drugs work by targeting fast-growing cancer cells, damaging their DNA and preventing them from dividing and multiplying. The drugs also affect normal cells that divide quickly such as those in the bone marrow, hair follicles, and digestive system. While chemotherapy can cause unpleasant side effects, it can be an effective treatment for many types of cancer.

It is worth noting that chemotherapy is a prevention strategy and we are yet to find treatment for cancer. 

Answer 2

Chemotherapy is a type of cancer treatment that uses drugs to kill cancer cells. The drugs work by targeting the rapidly dividing cells of the cancer, but can also damage healthy cells in the process. The drugs can be administered orally, intravenously, or topically, depending on the type of cancer and the individual patient. Chemotherapy can help to reduce the size of a tumor, eliminate cancer cells, and reduce the risk of cancer spreading to other parts of the body.

Comments

It is worth noting that chemotherapy, while serving as a treatment, cannot cure cancer, but only prevent the spread of it. 

Answer 3

Chemotherapy is a preventative treatment for cancer. It targets cancer cells that grow at an exponential rate by keeping them from multiplying. There are side-effects to chemotherapy.
