How to perform surgery when a tumor is found on the left ovary

Patient's question:

Detailed medical condition and consultation purpose: Left ovary with two large masses. I am concerned, so I am asking you whether I should have surgery immediately? Can laser treatment be used? Should I undergo further tests now? Thank you
History of previous diagnosis and treatment, as well as effectiveness: I have previously had adnexitis. A year ago, I fainted due to lower left abdominal pain and underwent an ultrasound examination, which suspected cysts. Three months later, a check-up showed no abnormalities, but after two more months, discomfort returned, and an ultrasound revealed two large shadows with a membrane. The doctor performed an internal examination and diagnosed it as a tumor. However, blood tests for the four tumor markers were normal, so the doctor advised me to come back for a follow-up in one month.

Doctor's answer:

Hello, the following conditions generally allow the preservation of the ovaries: ① Benign uterine fibroids, if the ovaries appear normal, doctors will try to preserve them; ② Young patients benefit more from preserving both ovaries than from preserving only one; ③ Patients over 50 who have not yet gone through menopause, if the ovaries are not atrophic during surgery, they are often preserved, but regular follow-up examinations are mandatory.
The following conditions require the removal of the ovaries: ① Uterine fibroids combined with endometrial cancer or ovarian malignancy, doctors will remove both ovaries; ② Postmenopausal patients with atrophic ovaries, doctors will remove both ovaries. If the patient refuses to have the ovaries removed, the doctor may preserve them, but the patient must undergo regular follow-up examinations.
