Detailed explanation-1: -Chemotherapy works by stopping or slowing the growth of cancer cells, which grow and divide quickly. Chemotherapy is used for two reasons: Treat cancer: Chemotherapy can be used to cure cancer, lessen the chance it will return, or stop or slow its growth.

Detailed explanation-2: -Chemotherapy (chemo) uses anti-cancer drugs that are injected into a vein (through an IV line or central venous catheter) or given by mouth as pills. These drugs enter the bloodstream and reach all areas of the body, making this treatment useful for cancer that has spread to organs beyond where it started.

Detailed explanation-3: -Chemotherapy drugs are powerful medications that attack rapidly growing cancer cells. Unfortunately, these drugs also attack other rapidly growing cells in your body-including those in your hair roots. Chemotherapy may cause hair loss all over your body-not just on your scalp.

Detailed explanation-4: -Chemotherapy and radiation therapy may cause changes in the lining of the mouth and the salivary glands, which make saliva. This can upset the healthy balance of bacteria. These changes may lead to mouth sores, infections, and tooth decay.

Detailed explanation-5: -Chemotherapy can cause nausea (feeling sick to your stomach) and vomiting (throwing up). Whether you have these side effects, and how often, depends on the specific drugs and dose. There are medications that are given before and after each dose of chemotherapy that can usually prevent nausea and vomiting.
