Uterine fibroids are the most common benign tumors in the female reproductive organs, with an incidence of about 30%. It is mostly seen in women aged 30-50 years. Different types of fibroids may manifest as excessive menstruation, lower abdominal masses or changes in urination or bowel habits. The appearance of these symptoms is closely related to the size, location and growth of fibroids. The smallest fibroids can be just a few millimeters, while the larger ones can reach dozens of centimeters. So what are the risks of fibroids for women? What other outcomes do giant fibroids lead to? Subplasmaline fibroids that grow toward the surface of the uterus usually have no menstrual changes. If the tumor is thin, it may twist at the tip and cause acute abdominal pain. In severe cases, if surgery is not performed immediately, the tumor may break off and form a free fibroid. Because of the absence of menstrual changes, they are often overlooked by patients and are only discovered when they grow to a large size. Such huge fibroids often lead to changes in local anatomy, making surgery more difficult. 2011 literature reported one case of death in a patient with damage to the posterior bladder wall and bilateral ureters during resection of a giant fibroid. Submucosal fibroids growing into the uterine cavity, although not large, mostly have abnormal bleeding. Gynecological inflammatory diseases such as adnexitis and pelvic inflammatory disease are caused by pathogenic bacteria invasion due to bleeding. Fibroids growing into the uterine wall can cause excessive menstrual bleeding, which can lead to secondary anemia and even anemic heart disease over time. In severe cases, the patient suffers from general weakness, pallor, shortness of breath and other adverse symptoms. The fibroids in the horn of the uterus compress the entrance of the fallopian tubes, deforming the uterus and preventing the fertilization of the egg, eventually leading to infertility or ectopic pregnancy. Fibroids are benign tumors, but there are still a few cases of malignant transformation. Most of them are seen in older people with large and fast-growing fibroids, especially those who have rapid growth of fibroids after menopause or those who have fibroids again after menopause should be more alert.
