Which age group is most commonly affected by serous cystadenocarcinoma?

Serous cystadenocarcinoma is a type of ovarian cancer that is most commonly found in women, particularly those who are postmenopausal. As women age, the risk of developing ovarian cancer increases significantly, with the majority of cases occurring after the age of 60. This aligns with the pathophysiological understanding that hormonal changes, cumulative exposure to ovulatory cycles, and genetic predispositions, such as mutations in BRCA1 and BRCA2, contribute to the increased incidence of ovarian cancers in older age groups.

In contrast, children and teenagers are generally much less likely to develop any form of ovarian cancer, including serous cystadenocarcinoma. Women in their 30s may have other types of ovarian masses, such as functional cysts or benign tumors, but the peak incidence of serous cystadenocarcinoma occurs later in life. Therefore, the highest prevalence in serous cystadenocarcinoma is found among postmenopausal women, making this the correct answer to the question.
