Although the tumor itself does not bleed, fibroid tumors can cause heavy bleeding, frequent urination or abdominal swelling, explains WebMD. However, many women with fibroids experience no symptoms.
Fibroid tumors are generally nonmalignant. The tumors are composed of muscle cells that form a tough, fibrous mass in the uterus. Submucosal fibroids are located under the uterine lining, while intramural fibroids lie between the uterine wall muscles. Subserol fibroids reach into the pelvic cavity from the uterine wall, according to WebMD. A complete hysterectomy was once the standard treatment for fibroids; however, with modern surgery options, a hysterectomy is not necessary most of the time.
