Hysterectomy

I have no idea where to post this! So I’m so sorry if wrong group. Has anyone had one?

I’m having on next week for early stages of cervical cancer and I think the nurse was saying they are leaving my ovaries intact but I’m not sure why? I don’t have my OP consultation for a few days so I figurednit might not hurt to see if anyone knows why they do that instead of removing all of it? Thanks(:
