What is a myoma (fibroid) tumour?
Myoma (fibroid) tumours are usually benign (non-cancerous) tumours most often found in the uterus. Although they occasionally develop in other organs which contain smooth muscle cells, they are the most common gynecological tumour in women. Until recently, hysterectomy was the preferred option for treating symptomatic myoma. Now, however, there are a number of uterine myoma (fibroid) treatments.
Types of myoma (fibroid) tumours
Myoma are categorised by where they grow in the uterus.
Subserous or subserosal myoma develop on the outside of the uterus and usually have the least symptoms. Subserous myoma can grow to be very large. Subserous myoma can become pedunculated as they grow, meaning they can develop a stalk.
Intramural myoma are located in the wall of the uterus and are the most common. They can cause the uterus to bulge.
Submucous or Submucosal myoma are found within uterine lining and can protrude into the uterine cavity. Generally, these are ones that can cause the most problems. Since they are located in the uterine endometrium, they can cause heavy orrolonged bleeding during menstruation.
Myoma (fibroid) tumour description
Myoma (fibroid) tumours are solid tumours which are made of fibrous tissue. Myoma tumours vary in size and number. Most often they are slow-growing and cause no symptoms. Approximately 25% of myoma tumours will cause symptoms and need medical treatment.
Myoma (fibroid) tumours may grow as a single nodule or in clusters and range in size from 1 mm to more than 20 cm in diameter. Myoma (fibroid) tumours are the most frequently diagnosed tumour of the female pelvis and the most common reason for a woman to have a hysterectomy. Although they are often referred to as tumours, they are not cancerous.
The cause of myoma (fibroid) tumours has not actually been determined, but most myoma develop in women during their reproductive years. Myoma (fibroid) tumours do not develop before the body begins producing estrogen. Myoma tend to grow very quickly during pregnancy when the body is producing extra estrogen. When menopause begins, myoma (fibroid) tumours generally stop growing and can begin to shrink due to the loss of estrogen.
Alternative names for myoma (fibroid) tumours are:
Fibroid Cysts, Fibroid Tumours; Leiomyoma; Fibromyoma; Fibroids
