What it calculates
The “CA-125” calculator computes Risk of Malignancy Index (RMI) from 3 parameters: ca-125 (U/mL), postmenopausal (1 = yes), ultrasound features (multilocular cyst, solid areas, metastases, ascites, bilateral lesions).
Used by professionals and patients to assess health metrics, dosages, and risks.
Example calculation
With parameters CA-125 = 35 U/mL, Postmenopausal (1 = yes) = 1, Ultrasound features (multilocular cyst, solid areas, metastases, ascites, bilateral lesions) = 1 the result is 105 (CA-125 can be raised by endometriosis, fibroids, inflammation and pregnancy).
How to use
- Enter ca-125, postmenopausal (1 = yes) and ultrasound features (multilocular cyst, solid areas, metastases, ascites, bilateral lesions) — each field above is adjustable with a slider.
- Risk of Malignancy Index (RMI) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.

FAQ
How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
