Is it reasonable to go from a 34DD cup to a 34B cup in a breast reduction surgery?

Thank you for your question.  Though substantial decreases in size can be obtained with a breast reduction there are a number of important considerations: the necessary amount of weight that needs to be removed for insurance coverage, maintaining breast size proportional to body size, not compromising your nipple viability, and improving your back pain, to name a few.  Be sure to see an ASPS board certified plastic surgeon for an in-person assessment and discussion.  

Thank you for your question.  Breast reduction surgery is one of the highest rated plastic surgery procedures in regards to aesthetic and symptomatic improvement.  I would start with a face to face consult with a Board
Certified Plastic Surgeon who has experience in breast surgery. During your
visit your surgeon should be evaluating your health to determine if you are a
good surgical candidate and examining your tissues to get a sense of what type
of procedure your tissues will allow. Only with a hands on exam can this be
determined. Once an exam and opinion is rendered then you can decide if surgery
is right for you. Best of luck.
