Endometrial polyp is not a precancerous lesion, it is a benign lesion, but this benign lesion has a relatively low incidence of cancer. Endometrial polyp is generally a benign tumor due to high level of estrogen or inflammatory factors in the body. Clinical manifestations include abnormal vaginal bleeding after menopause, or vaginal bleeding between menstruation, prolonged menstruation, etc. Generally speaking, small endometrial polyps can be followed up and observed on a regular basis without treatment, while larger polyps with symptoms need to be surgically removed. It is recommended that patients choose the appropriate treatment according to their own conditions under the guidance of their doctors, have regular checkups, and consult a doctor if they feel unwell, so as to avoid delays in their condition.
