Ovarian Cancer Risk Estimator
This calculator provides an *illustrative* estimate of potential ovarian cancer risk based on common factors. It is NOT a diagnostic tool and should not replace professional medical advice. Consult with a healthcare provider for personalized risk assessment and guidance.

Ovarian cancer is a type of cancer that begins in the ovaries, the female reproductive glands that produce eggs and hormones. It is often referred to as a "silent killer" because symptoms can be vague and easily mistaken for other conditions, leading to late diagnosis when the cancer is more advanced and harder to treat.
Key Risk Factors for Ovarian Cancer
While the exact cause of ovarian cancer is not fully understood, several factors are known to increase a woman's risk. It's important to remember that having one or more risk factors does not mean you will definitely get ovarian cancer, and many women who develop the disease have no known risk factors.
- Age: The risk of ovarian cancer increases with age, with most cases developing after menopause, typically in women over 50.
- Family History: A strong family history of ovarian, breast, or colorectal cancer (especially in first-degree relatives like a mother, sister, or daughter) can significantly increase risk. This is often due to inherited genetic mutations.
- Genetic Mutations (BRCA1/BRCA2): Inherited mutations in genes like BRCA1 and BRCA2 are the most well-known genetic risk factors. Women with these mutations have a substantially higher lifetime risk of developing ovarian cancer. Other genes, such as those associated with Lynch syndrome, also increase risk.
- Endometriosis: Women with a history of endometriosis (a condition where tissue similar to the lining of the uterus grows outside the uterus) have a slightly increased risk of certain types of ovarian cancer.
- Reproductive History: Women who have never had a full-term pregnancy (nulliparity) have a higher risk. Each full-term pregnancy appears to slightly reduce the risk.
- Hormone Replacement Therapy (HRT): Using estrogen-only HRT or combination estrogen-progestin HRT after menopause may slightly increase the risk, especially with long-term use.
- Obesity: Being overweight or obese may increase the risk of developing several cancers, including ovarian cancer.
Factors That May Decrease Risk
- Oral Contraceptive Pills (OCPs): Using birth control pills for several years has been shown to significantly reduce the risk of ovarian cancer, with the protective effect lasting for many years after stopping use.
- Pregnancy and Breastfeeding: Having full-term pregnancies and breastfeeding can lower risk.
- Tubal Ligation or Hysterectomy: Surgical procedures like tubal ligation (getting your "tubes tied") or hysterectomy (removal of the uterus) can reduce ovarian cancer risk, even if the ovaries are not removed.
How This Calculator Works (Illustrative Model)
This calculator uses a simplified scoring system based on several common risk and protective factors. Each factor is assigned a numerical value, and these values are summed to provide an illustrative risk score. The score is then categorized into different risk levels (e.g., average, moderately increased, high).
It is crucial to understand that this calculator is for informational purposes only and is not a substitute for professional medical advice or a clinical risk assessment. Medical professionals use more complex models, genetic testing, and personal health history to provide accurate risk assessments.
When to Consult a Doctor
If you have concerns about your ovarian cancer risk, especially if you have a strong family history, known genetic mutations, or persistent symptoms such as bloating, pelvic or abdominal pain, difficulty eating or feeling full quickly, or urinary symptoms (urgency or frequency), please consult your doctor. They can provide personalized advice, discuss screening options (though no routine screening is recommended for average-risk women), and recommend appropriate preventive strategies.
Examples of Risk Calculation:
Let's look at a few hypothetical scenarios using our calculator's logic:
Example 1: Average Risk Profile
- Age: 45 (1 point)
- Family History: None (0 points)
- BRCA Mutation: No (0 points)
- Full-Term Pregnancies: 2 (-2 points)
- OCP Use: 5 years (-2 points)
- Endometriosis: No (0 points)
Total Score: 1 – 2 – 2 = -3 points. Result: Lower than Average Risk.
Example 2: Moderately Increased Risk Profile
- Age: 62 (3 points)
- Family History: One first-degree relative (3 points)
- BRCA Mutation: No (0 points)
- Full-Term Pregnancies: 0 (0 points)
- OCP Use: 0 years (0 points)
- Endometriosis: Yes (2 points)
Total Score: 3 + 3 + 2 = 8 points. Result: Moderately Increased Risk.
Example 3: High Risk Profile
- Age: 55 (2 points)
- Family History: Two or more first-degree relatives (6 points)
- BRCA Mutation: Yes (10 points)
- Full-Term Pregnancies: 0 (0 points)
- OCP Use: 0 years (0 points)
- Endometriosis: No (0 points)
Total Score: 2 + 6 + 10 = 18 points. Result: High Risk.
