I had breast surgery using Mentor Extra around February 2019. Overall, I was satisfied, but gradually my body became strange and I started getting sick for no reason, so I ended up going to the hospital. I was young, but my joints also started hurting, so I was very scared, so I looked into it and found out that if the implant does not match, an immune reaction can occur. I had it removed less than a year after I found out . It was inserted through the arm and removed through the areola. I don't regret having it removed. Of course, there are many people who have had it in and had no problems for a long time, but this seems to be Sabasa. I hope everyone takes good care of it before getting the surgery!
