Uterine (Endometrial) Polyps
What are uterine (endometrial) polyps?
Uterine polyps, also known as endometrial polyps, are soft overgrowths that arise from the inner lining of the uterus, the endometrium. Polyps can have a broad base arising from the uterine lining or a thin stem extending into the uterine cavity.
Generally, uterine polyps are benign or non-cancerous, but may cause issues related to menstruation and fertility.
It is common for women with menstruation to have polyps, and it less commonly seen in women in menopause.
Uterine polyps vs fibroids
Like uterine polyps, fibroids are overgrowths but do not appear in the endometrial lining. They are overgrowths of the muscle inside the uterine walls.
In addition to heavy bleeding, fibroids also cause pain, and difficulty in urination and constipation. Learn more about growths such as fibroids, polyps, and ovarian cysts, and get a more in-depth look at uterine fibroids and their associated potential complications.
