 Hadari 
A widely recognized method of estimating the risk of malignant ovarian cancer is the risk of malignancy index (RMI), calculated based on an initial workup. An RMI score of over 200 or 250 is generally felt to indicate high risk for ovarian cancer.

 RMI = makin duban dan tayi × maki menopause x matakin CA-125 a U/ml.
