Superspecialisation in surgical oncology and in medical oncology difference?

Surg vs. med: Surgical oncology: surgeons who specialize in cancer. Med onc: internal medicine doctors who specialize in cancer. [see a longer answer to the same question that i just posted].

Surgery or medicine: As a broad answer, cancer is treated in 3 ways that may be used in combination -- surgical resection or biopsy, chemotherapy, or radiation therapy. Surgical oncologists do the surgery. Medical oncologists do the chemotherapy. Radiation oncologists do the radiation therapy. They often work together to deliver optimal treatment to the patient, depending on the type of cancer.

Training : In addition to the previous answers, there is a difference in training. Everyone does 4 years of medical school. Radiation oncology is then a 4-year residency. Medical oncology is a 3-year internal medicine residency followed by a 3-year hematology/oncology fellowship. Surgical oncology is a 5-year general surgery residency followed by a 2-year surgical oncology fellowship.
