A fibroid is a non-cancerous tumor that develops in the uterus, often during a woman's reproductive years. These growths are made of muscle and fibrous tissue and can vary in size, from as small as a pea to larger than a grapefruit. Fibroids can be found in different parts of the uterus, including the inner lining, the muscle wall, or on the outer surface. Many women with fibroids experience no symptoms, but some may have heavy menstrual bleeding, pelvic pain, or pressure in the abdomen. The exact cause of fibroids is not fully understood, but they are influenced by hormones like estrogen and progesterone. Treatment options include medication, lifestyle changes, or surgical procedures, depending on the severity of symptoms.
