Asymptomatic Endometrial Polyp Under 10 mm With No Abnormal Uterine Bleeding

This protocol applies to patients with a confirmed endometrial polyp who are entirely asymptomatic — no abnormal uterine bleeding — and whose polyp measures less than 10 mm. In this specific setting, the natural history and the associated malignancy risk differ meaningfully from symptomatic or larger polyps, and management is tailored accordingly.

Conservative management is recognised as a reasonable approach, particularly for small polyps in the absence of symptoms (Level A evidence). Evidence indicates that a meaningful proportion of small polyps may regress spontaneously, with smaller polyps more likely to resolve on their own compared with those 10 mm or greater. For asymptomatic postmenopausal patients, observation following a discussion of risks and preferences is also considered a valid option.
