1. What is the Ovarian Cancer Risk Calculator?

The Ovarian Cancer Risk Calculator estimates a woman's risk of developing ovarian cancer based on age, family history, and CA125 levels. It uses a Gail-like model to provide personalized risk assessment.

2. How Does the Calculator Work?

The calculator uses an ovarian cancer risk equation:

Where:

• \( Age \) — Age in years
• \( Family\ History \) — Presence of ovarian cancer in close relatives
• \( CA125 \) — Cancer antigen 125 level in IU/mL

Explanation: The equation accounts for known risk factors for ovarian cancer, with different weights assigned to each factor based on epidemiological studies.

3. Importance of Risk Assessment

Details: Accurate risk assessment is crucial for early detection and prevention strategies. Women at higher risk may benefit from more frequent screening or preventive measures.

4. Using the Calculator

Tips: Enter age in years, indicate family history, and provide CA125 level in IU/mL. All values must be valid (age between 18-120, CA125 > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is considered a high risk result?
A: Generally, risk above 5% is considered elevated, but interpretation should be done in consultation with a healthcare provider.

Q2: How accurate is this calculator?
A: The calculator provides an estimate based on population data. Individual risk may vary based on additional factors not included in the model.

Q3: When should CA125 be measured?
A: CA125 is best measured when not menstruating, as levels can fluctuate during the menstrual cycle.

Q4: What other factors affect ovarian cancer risk?
A: Additional factors include BRCA mutations, reproductive history, use of oral contraceptives, and endometriosis.

Q5: Should this replace medical advice?
A: No, this calculator is for informational purposes only. Always consult with a healthcare provider for personal medical advice.
