Early ultrasound of ovarian cancer can only show the presence of masses in one or both adnexal areas, including that they can be cystic or solid, and the boundary is usually unclear. If they are solid, the internal blood flow is usually richer; if they are cystic, they tend to have more solid components, rich blood flow, or more and thicker separation, or multiple copies of papillary projections larger than 3mm. Blood tests for tumor markers and elevated CA125 are also needed, as well as pelvic MRI for further evaluation. Ovarian cancer is one of the common malignant tumors of female reproductive organs, second only to cervical cancer and uterine body cancer in terms of incidence. If ovarian cancer is confirmed, it also requires extended surgery and further treatment with adjuvant radiotherapy after surgery.
