Endometrial hyperplasia includes simple hyperplasia and atypical hyperplasia. Simple hyperplasia is usually not serious, while atypical hyperplasia has cancerous tendency.
1. Simple hyperplasia: it is the most common type of endometrial hyperplasia, the hyperplasia involves the glands and interstitium, and the cells are diffuse. These cells are similar to endometrium in normal proliferative stage, with increased number of glands and cystic thorax of different sizes. The glandular epithelium was simple or pseudocomplex, with high columnar cells and no abnormalities. Mesenchymal cells are abundant and the probability of developing endometrial cancer is only 1%.
2. Atypical hyperplasia: Endometrial hyperplasia is usually due to the continuous stimulation of estrogen and abnormal growth of the endometrium. However, due to the absence of normal ovulation and the lack of sufficient progesterone to resist estrogen, the endometrium is unable to shed in a normal cycle, leading to degeneration. Endometrial atypical hyperplasia has a tendency to become cancerous and is therefore categorized as a precancerous lesion.
Patients with endometrial hyperplasia need to actively seek medical attention and be treated with medication under the guidance of a medical professional.
