same case po tau mommy.. actually i have 5 benign cyst sa right boob and im breastfeeding.. di naman po makakahinder sa pagpapabreastfeed and may benefit pa tau actually pag nagpapabreastfeed mas lower ung risk natin magkaruon ng ovarian, breast cancer at madami talaga benefit ang breastfeeding sa baby and to us moms.
Kung benign naman po mommy.. I don't think it can hinder you from breastfeeding..
