At the OHSU Knight Cancer Institute, our surgeons also have specific areas of expertise, so you will work with a doctor who understands your condition. Our team also includes surgical oncologists, who are fellowship-trained cancer surgeons.

Surgery, as defined by the American Medical Association, is the treatment of disease, injury or other disorders by direct physical intervention, usually with instruments. Surgery involves the cutting into the skin or other organ to accomplish any of the following goals:

  • Further explore the condition for the purpose of diagnosis
  • Take a biopsy of a suspicious lump
  • Remove diseased tissues or organs
  • Remove an obstruction
  • Reposition structures to their normal position
  • Redirect channels
  • Transplant tissue or whole organs
  • Implant mechanical or electronic devices
  • Improve physical appearance

Our surgeons treat all common and most rare cancers. The information search below will direct you to the team who treats your cancer and provide you with our treatment options.
When facing surgery, you should expect to go through several phases:

  • Surgical Diagnosis happens after medical tests and evaluations reveal a condition requiring surgery.
  • Preoperative Management begins from the time surgery is decided to the point when you are brought to the operating room.
  • Intraoperative Care lasts from the time you enter the operating room to when you go to the recovery room.
  • Postoperative Management lasts from entry to the recovery room until follow-up clinical evaluation.
