- With better control of side effects from chemotherapy, treatment is going more smoothly for many people with cancer. The goal of chemotherapy is to destroy cancer cells. Traditional chemotherapies work by killing cells that divide rapidly. But as they wipe out fast-growing cancer cells, they also can damage fast-growing healthy cells. Damage to healthy blood cells, for example, can lead to side effects such as fatigue or infection. Chemotherapy can also damage the cells that line mucous membranes throughout the body, including those inside the mouth, throat and stomach. This can lead to mouth sores, diarrhea or other issues with the digestive system.
