Uterine fibroids are the most common benign pelvic tumors in women. Fibroids are non-cancerous (benign) tumors that grow from the muscle layers of the uterus (womb). They are also known as uterine fibroids, myomas, or fibromyomas. Fibroids are growths of smooth muscle and fibrous tissue. Fibroids can vary in size, from that of a bean to as large as a melon.

Fibroids affect at least 20% of all women at some time during their life. Women aged between 30 and 50 are the most likely to develop fibroids. Overweight and obese women are at significantly higher risk of developing fibroids, compared to women of normal weight.

Malignant (cancerous) growths on the smooth muscles inside the womb can develop, called leiomyosarcoma of the womb. However, this is extremely rare.
