Abstract
Objective: To describe the researched screening methods for ovarian cancer, which are: transvaginal ultrasound, CA-125 antigen search, and doppler and their limitations. Bibligraphic review: each method has its positive and negative characteristics, which prevent its implementation as a screening method. Serum protein CA-125 is a great marker, but it generates many false positives; Doppler, on the other hand, has reasonable sensitivity and specificity for diagnosis, but is not capable of detecting small lesions, which is essential for initial diagnosis; and finally, transvaginal ultrasound is inexpensive, non-invasive, and widely accepted, but it cannot identify tumors in the epithelial layer of the ovary. Final considerations: This study is extremely important to disseminate information about the currently discussed screening methods and their limitations, which prevent ovarian cancer screening from being implemented nowadays. With the high lethality rate of this disease, there is a worldwide effort to diagnose ovarian cancer at an early stage and consequently reduce mortality, for this, studies are being increasingly produced.
