Would 500cc high profile be enough to go from a B cup to an E cup?

Cup sizes are not standard across bra makers, and implant sizing is NOT based on height, weight, BMI, or desired cup size.  This is something you will need to do IN PERSON with an experienced surgeon to determine what works well for you, and to get advice about if what you like is possible and what to expect with regards to results.  Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search.  

Thank you for your question.  There is not a direct correlation between breast cup size and the volume of implant that is chosen.  There are multiple variables that will ultimately determine the cup size.  This includes the patient's overall chest diameter and torso dimensions as well as the amount of breast tissue the patient already has.  Also as, as I am sure you have noticed, different bra manufactures will fit differently relative to size.  An experienced board certified plastic surgeon should be able to give you a relatively good estimate after a proper examination.  But also, as some others have suggested, you should consider that long term complication rates tend to increase as the size of the implant increases depending on your body frame and tissue integrity.  Again, an experienced board certified plastic surgeon should but able to council you so you are well informed after an examination.  Good luck with your surgery and with proper council from an experienced surgeon, I am sure you will have a great result!
