Chemotherapy targets rapidly dividing cancer cells, preventing them from growing and multiplying. However, because it can also affect healthy cells that divide quickly (e.g., cells in the hair, digestive tract, and bone marrow), it often leads to various side effects. Chemotherapy uses anti-cancer drugs to destroy cancer cells like leukemia and lymphoma. The type of chemotherapy will depend on the type, spread and location of cancer. It may also be used in conjunction or in combination with other types of cancer treatments.
