Epithelial ovarian carcinoma is the most common type of ovarian cancer, comprising more than 95% of cases. [5] There are five main subtypes of ovarian carcinoma, of which high-grade serous carcinoma (HGSC) is the most common. [5] Less common types of ovarian cancer include germ cell tumors [18] and sex cord stromal tumors. [5]
As ovarian cancer is rarely symptomatic until an advanced stage, [42] regular pre-emptive screening is a particularly important tool for avoiding the late stage at which most patients present. However, A 2011 US study found that transvaginal ultrasound and cancer marker CA125 screening did not reduce ovarian cancer mortality. [43]

Ovarian tumors, or ovarian neoplasms, are tumors in the ovary. [1] Not all are ovarian cancer. [1] They consist of mainly solid tissue, while ovarian cysts contain fluid. [2]In 2020, the World Health Organization (WHO) divided ovarian tumours as 90% epithelial, 3% germ cell, and 2% sex cord-stromal types.
Krukenberg tumors often come to the attention when they cause abdominal or pelvic pain, bloating, ascites, or pain during sexual intercourse.Krukenberg tumors can occasionally provoke a reaction of the ovarian stroma which leads to hormone production, that results in vaginal bleeding, a change in menstrual habits, or hirsutism, [3] or occasionally virilization [4] as a main symptom.
