Fibroid tumors are non-cancerous (benign) tumors found in the uterus of women aged between 30 and 40. Fibroid tumors can also develop on other organs that have smooth muscle cells. These tumors are named 'fibroid' tumors because they are solid tumors made of fibrous tissues. They grow as a single nodule or as multiple tumor masses; they grow slowly and show no symptoms.
Only 25% of the fibroid tumors show symptoms and therefore need treatment. While some tumors are microscopic others could be as big as a grape fruit and in rare cases they can cover the entire abdominal area. Uterine fibroid is the most common gynecological tumor in women.
Uterine fibroids are lumps of smooth muscle cells and fibrous connective tissues that grow within the wall of the uterus. The medical term for uterine fibroid tumor is uterine leiomyoma. They are non-cancerous fibroid tumors and the most common among pelvic tumors. These fibroids can grow as a single lump or as clusters and might vary in size (1mm to above 20cm in diameter).
They can grow either within the uterus or can project into the inner cavity or towards the outer surface of the uterus. Uterine fibroid tumors may be prevalent in 20% of women in their reproductive years and in 40% of women aged over 30years. These tumors do not affect women before the onset of menstruation cycle and after menopause. African-American women are highly prone to these tumors as compared to Caucasian women.
The exact reason for the development of fibroid tumors is not known; however it is noticed that fibroid tumor will not develop before the onset of menstruation. Fibroid tumors grow quickly during pregnancy when the body is producing additional estrogen.
The growth of fibroid tumor is spurred when pills containing estrogen are taken for either birth control or menopausal symptoms. When a woman attains menopause, chances of developing fibroid tumor is very unlikely. As she enters the menopausal phase the estrogen level in the body comes down and this discourages the growth of fibroid tumors, already existing tumors may begin to shrink and disappear.
Types of fibroid tumor
Submucous fibroids: They develop right below the lining of the uterus and can cause menstrual problems. They become painful as they grow and move about the pelvic region.
Subserous fibroids: These fibroids grow on the outer wall of the uterus and show no signs or symptoms until they grow and begin to interfere with the other organs of the body.
Intramural fibroid: This is a round type of fibroid that develops within the uterine wall and causes an enlargement in the uterus as it grows.
Interligamentous fibroid: This fibroid grows sideways amidst the ligaments which support the uterus in the abdominal area. It is not easy to remove this fibroid without interfering with the other organs or the blood supply of the body.
Pedunculated fibroids: These fibroids develop when a subserous fibroid develops a stalk (peduncle). They become more twisted and very painful as they grow bigger in size.
Parasitic fibroid: This is the rarest form of fibroid tumor and arises when a fibroid attaches itself to any other organ of the body.
Symptoms of fibroid tumors
Treatment for uterine fibroid tumors
Treatment is given depending on the size and the growth of the fibroid.
Surgery for uterine fibroid
Myomectomy: Removal of each individual tumor without any damage to the uterus thus safeguarding a woman's ability to conceive. Chances for the tumor to grow back are high and repeated myomectomy may cause problems to the uterus walls.
Uterine artery embalization: It is a non-surgical process where blood flow to the fibroid is cut off by placing polyvinyl particles in the uterine artery. These particles flow into the vessels and clog them thus totally cutting off blood supply to the fibroid. This will enable the fibroid to shrink in size and disappear.
Hysterectomy: Removal of the uterus is the most effective way to treat fibroids in women who have a complete family and are ready to get their uterus operated. This will get rid of the problem permanently.
