Uterine fibroids 0.8cm are not serious. Uterine fibroids are common and frequent benign tumors in women of reproductive age, and they can be subplasmic, interstitial or submucosal, and can be large or small depending on the location. Most fibroids grow over time in women of childbearing age because of the high estrogen and progesterone levels in their bodies. When a fibroid of 0.8 cm is found in the body, it is considered a very small fibroid, and most of them have no clinical symptoms, such as heavy menstrual bleeding and long periods, so there is no need to do any treatment for the time being, but it should be checked regularly to observe whether the fibroid grows quickly and whether there are clinical symptoms, so as to be alert.
