Fibroids very, very rarely turn into cancer, so women who have fibroids should not be too concerned about that. In this video, OB/GYN specialist Evelyn Minaya, MD, discusses how small the chances are of fibroids directly leading to cancer. 

Fibroids are almost always benign (not cancerous). Rarely (less than one in 1,000), a cancerous fibroid will occur. This is called leiomyosarcoma (leye-oh-meye-oh-sar-KOH-muh). Doctors think that these cancers do not arise from an already-existing fibroid. Having fibroids does not increase the risk of developing a cancerous fibroid. Having fibroids also does not increase a woman's chances of getting other forms of cancer in the uterus.

This information is based on source information from the National Women's Health Information Center.

Fibroids are benign (noncancerous) in 99% of the cases. When I see patients with fibroids, this is a very common question. There is a rare cancer of the uterus called a leiomyosarcoma, but this is thought to arise on its own and not from the transformation of a fibroid. Patients are also very worried that having fibroids can cause them to have an increased risk of other types of female cancers, and this is also untrue.

Uterine Fibroids

If you have uterine fibroids, you may never even notice that they are there. Ranging from the size of a small seed to grapefruit-sized, fibroids are tumors on the uterus that rarely cause harm. Some women have true discomfort with ...

fibroids, including pain in the abdomen or low back, or pain during sex. Sometimes, uterine fibroids can cause miscarriage, preterm labor, or even lead to infertility. Women in their 40s and 50s, women of African-American descent and women that are overweight are at higher risk of developing fibroids, although an estimated 20-80% of women will have them at some point before they turn 50. If your doctor notices fibroids during an ultrasound or pelvic exam, he or she may want to treat them with medication or surgery.
