If the right ovarian cyst is found during early pregnancy, the specific treatment can be decided according to the specific size and nature of the ovarian cyst and the symptoms. If the ovarian cyst itself is benign, less than 5 cm, and its growth rate is slow on review, it can be observed without medication or surgery, because pregnancy is a special time to try not to use medication or surgery. However, if the ovarian cyst is larger than 5 cm or if the growth rate is particularly fast on review, generally speaking, if the fetus is stable and there is no sign of pre-eclampsia, it is recommended that surgery be performed at 14-16 weeks of pregnancy to remove the ovarian cyst, which can effectively prevent the cyst from rupture or torsion due to the enlargement of the uterus in the middle and late stages of pregnancy. If the ovarian cyst itself is malignant in nature, surgery should be performed urgently, whether or not during pregnancy.
