Hi Heidi, no need to worry! I am a 21 year old college student from Belgium. I was also interested in correction of my congenital symmastia by undergoing breast augmentation surgery. After taking consultation from a renowned clinic, I decided to proceed with my congenital symmastia repair and breast augmentation process. A 390cc implant for left breast and 440cc implant for right breast was done to achieve better symmetry. I am happy and satisfied with the results.
