Hello,
With the question “Is it dangerous to have a single lobe ovarian cyst in 6 weeks of pregnancy? ", the doctor would like to answer as follows:
Single-lobed ovarian cyst is a type of ovarian cyst with ultrasound characteristics as 1 cyst without septum, if there are many with many septum, it will be called is a multi-lobed cyst. The characteristic of unilobular ovarian cysts is that small cysts appear in the ovary. Cysts may appear on one or sometimes both sides of the ovary and vary in size. During the time a woman ovulates, these follicles will likely reach their largest size from 15mm - 30mm.
With small-sized single-lobed ovarian cysts, the doctor will follow up for 2-3 months to screen for the possibility of malignancy. At this stage, the doctor can prescribe including birth control pills, pills containing the hormone Progesterone, etc. The effect of the drug is to limit the growth of the tumor. When managed with medication, benign cysts can gradually disappear.
However, when a single lobe ovarian cyst grows to the size of a lemon or larger. At this time, you need to apply interventions to completely remove harmful cysts that will limit the recurrence as well as reduce the risk of cancer arising. The surgical methods used are mainly open surgery or laparoscopic surgery.
Pregnant women will be encouraged by the doctor to have a cesarean section at the 4th or 6th month of pregnancy, if the pregnant mother detects the disease late, it is necessary to wait until the delivery is successful before performing surgery. The surgery is done carefully so as not to touch the ureters, intestines or bladder. However, the recurrence rate when applying surgical methods is still relatively high. Therefore, in elderly patients with no future fertility needs, it is best to have both ovaries removed. So, you are 6 weeks pregnant with a single lobe ovarian cyst that may be related to the hormonal changes of early pregnancy, the cyst can burst on its own, and go away without any treatment. However, you should have regular antenatal check-ups and re-examination when there are abnormalities: lower abdominal pain, vaginal bleeding, ... to be monitored and treated promptly.
