What benign tumors are commonly associated with heavy menstrual bleeding?

Uterine fibroids, also known as leiomyomas, are benign tumors of the uterine smooth muscle and are a common cause of heavy menstrual bleeding. These growths can vary in size and location within the uterus, and their presence may lead to increased blood flow during menstruation. Fibroids often disrupt the normal architecture of the uterus and can lead to symptoms such as heavy and prolonged periods, pelvic pressure, and discomfort.

While other options may also affect menstrual bleeding, fibroids are distinctly known for their significant impact on menstrual volume due to their mass effect and interactions with the uterine lining. They can cause alterations in the endometrial surface and contribute to myometrial contraction issues, thus exacerbating menstrual bleeding more than other benign tumors like ovarian cysts, which typically do not influence menstrual flow, or cervical polyps and endometrial polyps, which can cause irregular bleeding but not to the degree of heavy bleeding seen with fibroids.
