A medical oncologist will oversee the
treatment plan for chemotherapy. Depending on the type of lung cancer and the
stage, chemotherapy may be the main treatment, or it may be used in addition to
surgery. Anticancer drugs are injected or given by mouth. They enter the
bloodstream and flow throughout your body, which helps to fight cancers that
have spread. Side effects can include diarrhea, nausea, loss of hair, rashes on
hands and feet, mouth sores and fatigue. Most of these side effects disappear
once treatment ends.
