Uterine fibroids are the most common benign tumors of the reproductive system in women of childbearing age, mostly asymptomatic, with a few manifestations such as vaginal bleeding and pressure symptoms. Generally speaking, if patients have no clinical symptoms, they can be observed for the time being. Then many patients with fibroids in their reproductive age may ask: Can I get pregnant with tumors without surgery? There are certain risks associated with surgery, such as post-operative uterine adhesions, which can make it difficult to conceive. Also, the scarred uterus that results after surgery greatly increases the risk of, for example, uterine rupture and fatal placenta praevia. In general, fibroids rarely affect the fetus. The location, size and number of fibroids have some influence on pregnancy. In early pregnancy, the incidence of miscarriage due to fibroids is about 20%-30% due to the influence of the occupancy of the tumor. As long as the early stage of pregnancy, which is prone to miscarriage, can be safely passed, the pregnancy can be successfully continued. 2, mid-pregnancy, the mother-to-be should pay attention to the presence of abdominal pain, to consider whether the uterine fibroids occurred red degeneration. Red degeneration causes severe abdominal pain and fever, and may induce miscarriage or premature birth. Red degeneration occurs in a single large interstitial myoma, so these patients should pay extra attention. 3. Because of the occupying influence of the tumor, the space for fetal movement is limited, and there is a greater possibility of breech position, transverse position, fetal non-entry, placenta praevia or placental abruption, which increases the chance of cesarean delivery. However, the final delivery method will be decided by doctors according to the condition of pregnant women, not 100% of pregnant women with tumor need cesarean section to terminate pregnancy. 4.After delivery, due to the influence of uterine fibroids, the uterus may contract uncoordinatedly, which may lead to primary or secondary locking weakness, resulting in prolonged labor or even stalled labor. It may also affect the normal placental abruption and increase the risk of retained placenta and postpartum hemorrhage. In conclusion, all patients with uterine fibroids must be examined by a gynecologist and evaluated for surgical removal of the fibroids before deciding whether to have a pregnancy.
