Generally, treatments are given daily, weekly, or monthly. How often you receive chemotherapy depends on the type of cancer and which drug or combination of drugs you receive. Your doctor will help you determine the most effective treatment schedule for you. Chemotherapy is usually given in cycles with rest periods between each administration. Chemotherapy may be used in combination with surgery. When chemotherapy is given before surgery it is referred to as neoadjuvant chemotherapy. The goal of neoadjuvant chemotherapy is to shrink the cancer before it is surgically removed. If the chemotherapy is given after surgery, it is referred to as adjuvant chemotherapy. The goal of adjuvant chemotherapy is to kill any cancer cells left in the body after surgery. Regardless of whether it is given before or after surgery, chemotherapy will still be administered in cycles that depend on the type of cancer and which drug or combination of drugs.
