How serious is the shortage of general surgeons in the U.S.?
Arthur Perry, MD, Plastic/reconstructive Surgery, answeredThe shortage of general surgeons in the US is reaching a crisis point -- a third of rural hospitals do not have a general surgeon that lives in the same county as the hospital. Surgical emergencies require rapid trips to the operating room, and that is why the best hospitals have in-house general surgeons. But these are few and far between. Most do not. And as the shortage of general surgeons deepens, less will have that luxury. And that means when you wind up in a ditch on the side of the road in a rural area, you may be out of luck. And when you get that unbearable belly pain in the middle of the night that can only be fixed with the scalpel, or you need your spleen taken out because you just fell off your roof, you might not find a general surgeon in your hospital -- and that may cost you your life.
Why are BMT and PBSCT used in cancer treatment?
Riverside Cancer Care Center answered
One reason bone marrow transplant (BMT) and peripheral blood stem cell transplantation (PBSCT) are used in cancer treatment is to make it possible for patients to receive very high doses of chemotherapy and/or radiation therapy. To understand more about why BMT and PBSCT are used, it is helpful to understand how chemotherapy and radiation therapy work.
Chemotherapy and radiation therapy generally affect cells that divide rapidly. They are used to treat cancer because cancer cells divide more often than most healthy cells. However, because bone marrow cells also divide frequently, high-dose treatments can severely damage or destroy the patient's bone marrow. Without healthy bone marrow, the patient is no longer able to make the blood cells needed to carry oxygen, fight infection, and prevent bleeding. BMT and PBSCT replace stem cells destroyed by treatment. The healthy, transplanted stem cells can restore the bone marrow's ability to produce the blood cells the patient needs.
In some types of leukemia, the graft-versus-tumor (GVT) effect that occurs after allogeneic BMT and PBSCT is crucial to the effectiveness of the treatment. GVT occurs when white blood cells from the donor (the graft) identify the cancer cells that remain in the patient's body after the chemotherapy and/or radiation therapy (the tumor) as foreign and attack them. (A potential complication of allogeneic transplants called graft-versus-host disease.)

How is robotic surgery used in oncology?
Honor Society of Nursing (STTI) answered
Robotic surgery is used in oncology for surgeries in areas that are hard to access via traditional surgery. A robot performs the surgery, while a surgeon remotely controls it. 3-D images help to guide the surgeon's movements. Robotic surgery is generally only available in very specialized treatment facilities.
