Our program has been recognized by the American College of Surgeons for adhering to the highest standards of care. We’re the only health care system in the Bay Area with this accreditation, which we’ve continuously held since 2009.
A gynecologic oncologist is a surgeon who specializes specifically on the diagnosis and treatment of cancers within a woman’s reproductive system. In addition to a four-year residency in obstetrics and gynecology, a gynecologic oncologist also pursues three to four additional years of intensive subspecialty training through an accredited gynecologic oncology fellowship.
Studies repeatedly show that women treated by a gynecologic oncologist are more likely to have better outcomes, including higher survival rates, than those treated by non-specialists. Due to the extra years of subspecialty training, gynecologic oncologists have a remarkable breadth of specialized skills—from advanced diagnostic capability to surgical skills for the removal of tumors, and even the administration of chemotherapy.
Beyond offering the best possible care and the most advanced treatment options available, we believe in empowering you with the knowledge to be an integral part of the decision-making process. Throughout your treatment and recovery, we make sure you know exactly what to expect and what options are available to you—as we’re firm believers that expert care, combined with a supportive environment, helps with the healing process.
In addition to diagnosing and treating gynecologic cancers, we also offer genetic counseling and testing for women who may be at high risk for developing one.
