What is the most common type of endometrial carcinoma?

The most common type of endometrial carcinoma is adenocarcinoma, specifically the endometrioid subtype. Endometrial adenocarcinoma arises from the endometrial lining of the uterus and is associated with estrogen exposure, obesity, and other risk factors. This cancer typically presents in postmenopausal women and can cause abnormal uterine bleeding, which is one of the hallmark symptoms prompting further investigation.

Adenocarcinomas are classified based on the specific histological characteristics, with endometrioid carcinoma being the predominant form, accounting for a significant majority of cases diagnosed. Understanding this distinction is crucial for treatment and management strategies since the prognosis and therapeutic approaches may differ based on the specific type and grade of carcinoma present.

While other types, such as clear cell carcinoma and squamous cell carcinoma, exist and may present in certain cases, they are less common and often associated with different clinical characteristics and behavior. The prevalence of endometrioid carcinoma emphasizes the importance of recognizing and distinguishing these types in gynecological practice.
