Suggest Treatment For Cyst On Chest

i am a teenager and i have a cyst on my chest (between my breast) . it goes away and keeps comming back and i have already tried antibiotics. it is very painful . and i have heard that cysts can spread so i was wondering would it end up spreading to my heart or to my breast and end up giving me breast cancer?? ...i have also heard that getting it drained will leave a huge mark..if i get it cut out would it leave a mark? ..and what are the risks of getting surgey???
