According to the UCSF Medical Center, these growths are very common and can affect up to 50 percent of women at some point in their life. Fibroids affect mostly women in their 30s and 40s and tend to affect African-American women more frequently.
Uterine fibroids are benign lumps that grow on the uterus. Symptoms may include heavy periods, cramping, painful sex, and an urge to urinate.
They rarely turn into cancer, and if you get them it doesn’t mean you’re more likely to get uterine cancer.
Fibroids can vary a lot in size, shape, and location. They can show up in your uterus, uterine wall, or on its surface. They can also attach to your uterus by a stalk- or stem-like structure.
Some are so small that your doctor can’t even see them with the naked eye. Others grow in big masses that can affect the size and shape of the uterus.
