Fibroids are abnormal growths that develop in or on a woman’s uterus. Sometimes these tumors become quite large and cause severe abdominal pain and heavy periods. In other cases, they cause no signs or symptoms at all. The growths are typically benign, or noncancerous. The cause of fibroids is unknown.
Fibroids are also known by the following names:
• uterine myomas
The type of fibroid a woman develops depends on its location in or on the uterus.
Intramural fibroids: Intramural fibroids are the most common type of fibroid. These types appear within the muscular wall of the uterus. Intramural fibroids may grow larger and can stretch your womb.
Subserosal fibroids: Subserosal fibroids form on the outside of your uterus, which is called the serosa. They may grow large enough to make your womb appear bigger on one side.
Pedunculated fibroids: Subserosal tumors can develop a stem, a slender base that supports the tumor. When they do, they’re known as pedunculated fibroids.
Submucosal fibroids: These types of tumors develop in the middle muscle layer, or myometrium, of your uterus. Submucosal tumors aren’t as common as the other types
