Frequently Asked Questions
Q: How many women are diagnosed with ovarian cancer in BC each year?
A: Approximately 310 women in BC are diagnosed with ovarian cancer in B.C. each year.
Q: What are the survival rates for women diagnosed with ovarian cancer?
A: Most cases of high grade serous ovarian cancer are diagnosed at an advanced stage (stage 3 or 4) and the disease is widespread. In these cases, the 5 year survival rates are 15 per cent. For those diagnosed early in stage 1 or 2, the five year survival rate is much higher at approximately 80 per cent.
Q: How many women die from ovarian cancer each year in B.C.?
A: Approximately 220 women will die from ovarian cancer each year in B.C.
Q. What is a high grade serous cancer?
A: High-grade serous carcinomas are distinct neoplasms with different pathogenesis, behavior, and response to treatment than low grade tumours. They are aggressive tumours that usually grow quickly and spread widely before diagnosis. Although these tumours typically respond well to initial treatment with surgery and chemotherapy, the goal of cure is illusive.
Q: What are the signs and symptoms of ovarian cancer?
A: Symptoms of ovarian cancer are often vague, you should see your physician if some of the following symptoms persist or progress for 2 to 3 weeks: abdominal discomfort, pressure or pain, abdominal swelling, change in bowel habits, feeling full after a light meal, indigestion, gas, upset stomach, fatigue, more frequent or urgent urination, abnormal vaginal bleeding.
Q: Isn’t ovarian cancer one disease?
A: Ovarian cancer is now known to have a number of subtypes, which originate in different areas, develop in different ways, and respond differently to treatment. Some of the commonly known ovarian cancer subtypes are: high-grade serous cancer, clear cell carcinoma, and endometrioid cancer.
Q: I have endometriosis; does this mean I will one day develop ovarian cancer?
A: Recently it was discovered that endometriosis is linked to two types of ovarian cancer, but this does not mean that every person with endometriosis will develop ovarian cancer.
Prevention: Removing the Fallopian Tubes
Q: Aside from surgical removal of my fallopian tubes, are there other ways to reduce the risk of developing ovarian cancer?
A: Currently, there is no known screening test for ovarian cancer. It’s known that use of the oral contraceptive, pregnancy, tubal ligation and breastfeeding all lower the risk of ovarian cancer.
Q: I have a scheduled hysterectomy in the coming months, should I talk to my physician to ensure they remove my fallopian tubes at the same time?
A: Absolutely. Your gynecologist will be the best person to talk to about your coming surgery.
Q: I have already had a hysterectomy, is it likely that I still have my fallopian tubes?
A: If your ovaries were left in place at the time of your hysterectomy, it is most likely that you still have your fallopian tubes. Removing the fallopian tubes is a new change in surgical practice. To be sure, you can check with the surgeon who performed your surgery.
Q: Should I have my fallopian tubes removed now if I’ve already had a hysterectomy or tubal ligation?
A: We would not suggest undergoing a surgical procedure to remove the fallopian tubes as the sole indication for surgery.
Q: Does having my fallopian tubes removed increase the risk of my surgery?
A: For women undergoing gynecologic surgery for other valid indications, fallopian tube removal does not meaningfully increase the surgical risks.
Genetic Mutations in Ovarian Cancer
Q: I was recently diagnosed with ovarian cancer, should I be tested for the BRCA gene mutation?
A: There are several types of ovarian cancer and we are recommending that all patients diagnosed with high grade serous ovarian cancer be referred for genetic counseling and testing.
Q: My mother had ovarian cancer, should I have testing for the BRCA 1 and 2 gene mutations?
A: That depends on a complete understanding of your entire family history. Your physician can consult the BC Cancer Agency’s Hereditary Cancer Program for specific referral criteria.

Q: How do I access genetic testing for ovarian cancer?
A: You must be referred by a physician.
Q: I’ve had genetic testing for the BRCA gene mutation and it was positive, should I have a hysterectomy and remove my fallopian tubes?
A: It is important that every BRCA mutation carrier have a thorough understanding of her risks and options for risk reduction. You will likely be referred to a Gynecologist or Gynecologic Oncologist for a complete individualized discussion. You will also need to review your options for Breast Cancer screening and risk reduction.
