Oncologic surgery is used in cancer treatment for several purposes:
- Preventative: Surgical Procedures performed in order to remove tissue that does not yet contain cancer cells, but may become cancerous in the future. This also may be referred to as prophylactic surgery.
- Diagnostic: Surgical Procedures performed in order to remove samples of tissue from a suspicious area for testing and evaluation (in a laboratory by a pathologist) to confirm a diagnosis, identify the type of cancer, or determine the stage of the cancer.
- Curative: Surgical Procedures performed in order to remove or destroy cancerous tissue, which may include removal of some tissue around the tumor and nearby lymph nodes.
