Uterine Fibroids Things to Know About Uterine Fibroids Whether you have been diagnosed with uterine fibroids or simply wonder if you might have them, it is good to have some background information on this often challenging condition. Fibroids are made from muscle and connective tissue. They come in many different sizes—from smaller than a pea to larger than a melon. Fibroids also come in several different forms. Fibroids can extend from the inner uterine walls on “stalks.” They can be located within the uterine wall itself. They can also be attached to the outside of the uterus. Fibroids rarely lead to cancer. Current data show that fibroids lead to cancer less than 1% of the time. Many women have fibroids and don’t know it. About 7 women out of 10 have at least one uterine fibroid. If fibroids are not causing problems, they rarely require treatment. So if fibroids are not causing symptoms like discomfort or bleeding, or causing other issues such as infertility, they will most likely not need to be treated. Hysterectomy is not the only treatment option. In the past, uterine fibroids were frequently treated by hysterectomy—removal of the uterus. This is not necessarily the preferred treatment option today. No one knows what causes fibroids. While estrogen encourages fibroids to grow, it does not cause them in the first place. Uterine fibroids cannot be cured through diet. There is no evidence to suggest that any diet can make fibroids shrink or disappear. Many women are able to get pregnant after treatment for uterine fibroids. New treatment options that remove fibroids through small incisions while sparing the uterus have helped numerous women become pregnant.
