Your doctor may suggest that you get more than 1 type of treatment. Getting 2 or more treatment types is called combination treatment or combination modality treatment.
For instance, you may have surgery and chemotherapy. Or you may have surgery and radiation, or radiation and chemotherapy. You may even have all 3 types of treatment.
The order that you get treatments has a specific name. For instance, when you have a treatment before having surgery, it is called neoadjuvant treatment. You may have chemotherapy and/or radiation before surgery. These help shrink the tumor. A smaller tumor is easier to take out. They also help keep the cancer from spreading.
Or, you may have more treatment after surgery. This is called adjuvant treatment. You may have chemotherapy or radiation soon after surgery. The goal is to kill any cancer cells that are left. Even if there is no sign of cancer, your doctor may still suggest adjuvant treatment. Having it reduces the risk that cancer may come back or spread.
