Mine was repaired at 5.2 cm (52mm), it was considered large, especially for my body size. My surgeon told me it was actually larger than originally measured when he removed it.

I would find the best surgeon accessible to you, someone who has done hundreds or thousands of these surgeries in a major hospital and get a second opinion ASAP.

You are definitely in the critical zone, keeping your BP in control is crucial.

All the best!!
