Billings Clinic Cancer Center Gynecologic Oncology Services

Gynecologic oncology is the medical care of female reproductive cancers or pre-cancerous conditions. Billings Clinic Cancer Center has the only board-certified gynecologic oncologists in Montana and Wyoming.

Exceptional Care

The gynecologic cancer team at Billings Clinic Cancer Center treats women with cancer of the female reproductive tract. We recognize that each patient and each case is different, and we customize treatment to individual patients’ needs with input from the patient, her family and her referring physician.

Our gynecologic cancer team includes board-certified regional leaders in the research and application of new treatments and the development of new and effective drug therapies. Patients will benefit from gynecologic cancer specialists' many years of experience with difficult pelvic surgeries.

In addition to our gynecologic cancer physicians and physician assistants, our team includes:

  • your OB/GYN or Family Medicine physician
  • radiation oncologists
  • a registered nurse and patient navigator
  • surgical staff
  • counselors including a genetic counselor, licensed counselor, and financial counselor
  • a dietitian

These specialists meet weekly to discuss patient care, providing a combined expertise not always available at other cancer centers.


Patients with a gynecologic cancer or pre-cancerous condition may include:

  • Women who have pelvic cancers such as cervical, endometrial, ovarian or vulvar cancer
  • Women with abnormal Pap smears or cervical lesions requiring further examination
  • Women with abnormal uterine bleeding
  • Women with vulvar irritations or lesions
  • Women with ovary, fallopian tube, or pelvic masses
  • Women with gynecologic cancers that have recurred, or returned
  • Women who were diagnosed with a gynecologic cancer at another facility or who have received treatment elsewhere and were referred to Billings Clinic Cancer Center for treatment.

Treatment of gynecologic cancers may include surgery, chemotherapy, high dose rate (HDR) brachytherapy and participation in clinical trials. As gynecologic oncologists, our physicians are sub-specialists of gynecology, surgical oncology and medical oncology. In this specialty, the gynecologic oncologist performs the cancer surgery, delivers the systemic therapies (usually chemotherapy), and works with a radiation oncologist to deliver brachytherapy treatment.

Our gynecologic oncologists offer minimally invasive robotic surgery using da Vinci Surgical System.

In addition, each patient is offered a full range of support services to meet their physical, emotional and spiritual needs. Please see our Cancer Center Resources and Support Services for more information.

Dr. Justin Bottsford-Miller, Dr. Megan Petersen and Dr. Erin Stevens lead an exceptional team including a registered nurse/patient care navigator, physician assistants, LPNs and medical assistants, caring exclusively for patients with gynecologic cancers.

Billings Clinic Cancer Center is affiliated with the Gynecologic Oncology Group (GOG), a national clinical trials group. Patients also can take part in studies with the Radiation Therapy Oncology Group, a group dedicated to radiation therapy trials, and receive new cancer therapies offered through clinical studies initiated by Billings Clinic researchers and physicians.
