Cancer treatment depends on the cancer type, stage, biomarkers, location, overall health, and treatment goals. Many patients receive more than one kind of treatment over time.
This guide explains common treatment categories so you can ask clearer questions before a second opinion.
Surgery
Surgery may be used to remove a tumor, collect tissue, stage cancer, relieve symptoms, or prevent complications. In some cancers, surgery is the main treatment. In others, it is combined with chemotherapy, radiation, immunotherapy, or targeted therapy.
Radiation therapy
Radiation therapy uses high-energy radiation to treat cancer cells in a specific area. It may be used before surgery, after surgery, instead of surgery, or for symptom relief.
Chemotherapy
Chemotherapy uses medicines that affect fast-growing cells. It may be given before surgery, after surgery, with radiation, or for cancers that have spread. Side effects vary by drug and dose.
Immunotherapy
Immunotherapy helps the immune system recognize or attack cancer. It is important for some cancers but is not appropriate for every cancer type or stage.
Targeted therapy
Targeted therapy focuses on specific features of cancer cells, often based on biomarkers or genetic changes in the tumor. Testing may be needed to know whether a targeted treatment is relevant.
How to compare options
Ask what each treatment is meant to do, how success will be measured, what side effects are likely, what alternatives exist, and what would happen if treatment is delayed.
