If observed the cyst and it is small and simple, there will be no further management, meaning that only the sack will build up fluid and it is less than five centimetres. Would consider it to be a physiological or follicular cyst that develops as part of the normal function of the ovaries.
This is usually between five and seven centimetres and usually need recheck with a pelvic ultrasound in about one to three months time.
A large cyst, would recommend surgery. The surgical treatment would also be recommended for smaller cysts which are not simple. For example, endometriomas, or dermoid cysts will be treated surgically.
Surgery may be recommended if patient have a large cyst, cysts in both ovaries, or other characteristics that may suggest ovarian cancer. Ovarian cancer can occur in women of all ages, but the incidence increases after menopause.
