I am post op 3 years and i am having mine done again on monday. i went from a 32b to a 32c with 260cc implants. as soon as i woke up from my suregry last time i knew they would be too small for what i wanted. I went with a different clinic last time and compared to Mya they were really unhelpful!
Im now booked in for 375/400cc implants which will hpefully give me the size i wanted previously. My surgeon has been so amazing and im so excited.
Depending on what you have to have done (ive heard some people have more scar tissue/ other factors, sorry not technical :)) it does cost more as they have to take out old implants sort out any imperfections then put new ones back in. i think mine was around £6k but this varies depending x
