I recently had a partial hysterectomy about 3 months ago and discovered last month that i have an ovarian cyst, does it need to be removed?

OVARIAN CYST: Ovarian cyst are not usually removed if size is less than 2 cm. It depends if with associated sx like back or abdominal pain. The gyne will discuss with you.

No: Not unless it is causing bad symptoms or has features worrisome for cancer. Cancer is unlikely since your surgeon just looked at the ovary 3 mo ago. The cyst should be followed with periodic ultrasounds to make sure it resolves and does not develop worrisome features.
