If you are pregnant with an 8 cm ovarian cyst, you can continue the pregnancy if it is a simple cystic mass and has not increased significantly on regular examination. Otherwise, termination of pregnancy is recommended. 1. Continuation of pregnancy: If the cystic mass is simple under ultrasound, with good acoustic translucency and clear boundary, and no obvious increase in size under regular examination, it can be left untreated for the time being, and regular examination is sufficient. If there is no sign of miscarriage, pay attention to rest during the period, you can wait for the mid-pregnancy or cesarean section together with the cyst to be surgically removed under the evaluation and guidance of the doctor. 2. Termination of pregnancy: If the cyst is found to grow rapidly within a short period of time during regular checkups, or if the cyst is found to be a malignant tumor, which may affect the normal growth and development of the fetus, termination of pregnancy should be considered.
