I got rid of mine in December 2016. I did it at the same time I had my port put in, a week or so before chemo. I had wicked shoulder pain for a couple of hours which is caused by the gas they use to inflate your tummy during the op and some minor problems with dissolvable stitches a couple of weeks later, but apart from that I was up and about very quickly.
I haven't had any testing done, but as I'd had a recurrence and knew I'd be on AI for years, I figured being rocketed into full menopause (the last step is a doozy) was a small price to pay compared to Zolodex injections and the worry that I'd develop ovarian cancer too.
I've never regretted it. The game plan is to keep my oestrogens to a minimum which was always going to have its own unpleasant set of side effects whether I did it physically or chemically. Mxx
