Gynecologic Oncology

If you have a female reproductive cancer or if pre-cancerous conditions are present, you will want to see a specialist. Billings Clinic Cancer Center has the only board-certified gynecologic oncologists in Montana and Wyoming. Additionally, our gynecological cancer specialists provide surgical and clinical outreach services in Great Falls, Missoula, Helena, and Bozeman.

Our team takes a holistic approach to your care and customizes your treatment based on input from you, your family, and your referring physician. We understand that each case is different and design our treatment accordingly.

Our gynecologic cancer team is trained in state-of-the-art treatments and drug therapies and has years’ of experience with difficult pelvic surgeries.

Gynecologic cancer or pre-cancerous conditions may include:

  • Pelvic cancers such as cervical, endometrial, ovarian, or vulvar cancer.
  • Abnormal Pap smears or cervical lesions requiring further examination.
  • Abnormal uterine bleeding, vulver irritations, or lesions
  • Ovary, fallopian tube, or pelvic masses.
  • Recurrent gynecologic cancers.
  • Women diagnosed at another facility or who received treatment elsewhere and were referred to Billings Clinic Cancer Center for treatment.


As gynecologic oncologists, our physicians specialize in gynecology, surgical oncology, and medical oncology. Treatment for gynecologic cancers may include:

  • Surgery
  • Chemotherapy
  • High dose rate (HDR) brachytherapy
  • Participation in clinical trials
  • Hyperthermic (or Heated) Intraoperative Peritoneal Chemotherapy (HIPEC) is a procedure used to deliver heated chemotherapy directly into the abdomen to penetrate diseased tissue, killing cancer cells and slowing cancer growth.
