You can expect to need to prepare for oncology surgery. Your oncologist may perform a number of tests, including blood tests and urinalysis, just before your surgery to assess your needs and risk levels during surgery. You will probably need some form of anesthesia during surgery. Local, general, and regional anesthetics are used, depending on the type of procedure performed. You may need to remain hospitalized after your surgery. Follow your oncologist's instructions during the recovery period.
