Surgery is one of the most common treatments for cancer. It’s used for a variety of reasons, including to determine a diagnosis and staging through biopsy, tumor removal or reduction (also called debulking) and palliative surgery to help relieve symptoms. Some patients have surgery alone, while others undergo surgery as part of an overall plan that may include radiation therapy, chemotherapy and other treatments.

Surgical oncologists or general surgeons may perform surgeries to treat different cancers, especially solid tumors and those contained to one area. Whether surgery is recommended depends on several factors, including the type of tumor, its location and its stage when diagnosed. Providers also consider the patient’s preferences for treatment, age and ability to tolerate surgery.

About 780 surgical oncologists are practicing in the United States, according to the American Society of Clinical Oncology’s 2018 annual practice survey. The survey found most belong to small oncology practices that employ between one and five oncologists.

What is a surgical oncologist?

Surgery is performed by physicians who are specially trained in surgery and have focused their training on diagnosing and treating cancer.

Surgical oncologists work with the cancer care teammedical oncologists, oncology nurses, radiologists, pathologists and those with a range of other medical specialties—to provide comprehensive cancer care.

Though surgical oncologists focus on cancer-specific surgeries, general surgeons also may perform these procedures. That’s particularly true for the more common cancers that require surgery: breast, skin (melanoma) and lower gastrointestinal tract (colorectal).

Surgical oncologists often work with medical oncologists, who may deliver chemotherapy if needed. In recent years, surgical oncologists have become more multidisciplinary and may offer treatments and procedures like advanced genomic testing, targeted therapy, neoadjuvant therapy and adjuvant therapy.

What training does a surgical oncologist receive?

To become a surgical oncologist, students must obtain a bachelor’s degree and graduate from medical school, typically a four-year program. They also must complete a residency, which may last three to seven years, then a fellowship in cancer surgery studying the removal of cancerous tumors. Most surgical oncology fellowships require an additional two years of study.
