Segmentation within the ovarian capsule is not a sign of cancer. Ovarian cystic separation is more or less considered to be caused by polycystic ovaries, that is, ovarian cysts with multiple small cysts fused together and separated. Ovarian endometriosis can also show segmentation. Most ovarian cancers show unsmooth cystic walls, with papillary tissue projecting into the cystic cavity, which can appear as segmentation, and the size of the tumor is relatively large. Further examination is needed to diagnose whether it is ovarian cancer or not. The treatment of ovarian cysts is mainly based on surgery, while the treatment of ovarian cancer is mainly based on surgery and radiotherapy and chemotherapy. Regardless of the cause of ovarian lesions, they will affect normal ovulation and conception, and need timely and symptomatic treatment to avoid affecting normal fertility.
