well its going to depend on what the surgeon does , for ex if the surgeon removes the gland which is typical they need to take tissue from some where and do a fat sculpt to fill in behind your nipps , if they didn't your nipps would be caved in ,and to do this they may actually leave about 5% of the gland , cause after all he dosen't know you are going to be on the sauce so thats why they use a little bit of the gland to do the fill in and its convienant for them , so YES YES YES you will get it again. you need to use your doc painent confidentiatly and tell him what you are up to so that he may remove the entire gland ,your chances of getting gyno again without gear are slim to none , but if you continue to cycle your chances are 50 % or better . if i were you , cycle now and learn how to controll it so after the surgery you will know how to avoid it all together
