Uterine fibroids or leiomyomata are areas of smooth muscle cells and fibrous connective tissue that develop in or on the uterine wall. You can develop one fibroid or many of them. Fibroids are the most frequently diagnosed tumor of the female pelvis and the most common reason for a woman to have a hysterectomy. They are benign – not associated with cancer – and rarely become cancerous.
Types of Fibroid:
It is estimated that at least 20-30% of women have fibroids.
The cause of fibroids has not been determined but most fibroids develop in women during their reproductive years. Fibroids need a rich blood supply and estrogen stimulates their growth. Once menopause has begun, fibroids generally stop growing and can begin to shrink due to the loss of estrogen.
Uterine fibroids range in size and location. It is their size and location that determine the possible symptoms you may have. Fibroids can be found during a routine gynecologic examination. Many women do not know they have fibroids because they do not experience any symptoms. Some women only discover that they have fibroids when they become pregnant.
Sometimes it is recommended that you "wait and see" what will happen. This approach is most practical when menopause is not far away and when symptoms are limited. Fibroids generally continue to grow until menopause.
Fibroids may cause infertility, miscarriage and early labor. However, many women have carried to term with fibroids. If your doctor recommends getting pregnant while you have fibroids, you may wish to consider getting a second opinion.
Submucous fibroids are the type that most commonly cause significant problems; even small tumors located in or bulging into the uterine cavity may cause heavy bleeding, anemia, pain, infertility or miscarriage.
Mural fibroids (located in the uterine wall) and subserous fibroids (protrude outside the uterine wall) may reach a large size before causing symptoms. These symptoms may include pressure on the bladder with difficulty voiding or urinary frequency and urgency, pressure on the rectum with constipation, lower back and abdominal pain, as well as heavy or irregular bleeding during periods.

The growth of uterine fibroids is estrogen dependent, which means that fibroids tend to stop growing – and often shrink – after menopause.
Estrogen levels have persistently been shown to be elevated in patients with uterine fibroids.

Uterine fibroids are often associated with elevated levels of estrogens.
Though systemic progesterone use is often indicated, intravaginal application of progesterone cream may provide higher doses to the area needing it, and counter an estrogen dominance at the site.
Injections into a nerve plexus near the uterus is said to stabilize and sometimes shrink fibroids.
A new procedure called Uterine Artery Embolization is considered to be less invasive than other procedures and enjoys a high success rate. It involves cutting off the blood supply to the fibroid by placing a catheter into the uterine arteries and injecting small particles. This blocks the blood flow and causes the fibroid to degenerate, leaving the remainder of the organ intact. Often this is a better approach than a hysterectomy.
