Would 70ccs make a difference on a small frame? I'm currently a 30dddd/g with the 470ccs and want to be a 30dd

Hi, I'm sorry you were pressured into something you did not want. As a 30G you will need to downsize at least 200 cc to achieve a 30DD bra size. Now, please take into consideration that bra manufacturers vary in sizing. In other words, don't get stuck on a number. I agree that a G cup is quite large for a person of your frame. Large implants (>300cc) are typically the cause of most breast augmentation revisions due to their unstable nature. The heavier the implant the more likely they are to cause chronic pain, soft tissue damage (regardless of where they are placed), capsular contracture, implant displacement, and other types of disfigurement. A 70cc reduction will not give you a DD cup. I hope this helps.Best wishes and kind regards,

Thank you for the question. In the end, exactly what operation you should undergo and what type/size/profile of breast implant should be utilized will depend mainly on what you are trying to achieve (in other words, what your goals are).There is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved. For example, I do not think that the generalizations of "200 cc equates to 1 cup" hold any validity or are helpful in any specific or practical way.  In my practice, I ask patients NOT to communicate their goals, or evaluate the outcome of the procedure performed, based on cup size references.
 During downsizing of breast implant surgery (sometimes) adjustment of the breast implant pockets (capsule adjustments) may be necessary to achieve the outcome you are looking for. Breast lifting may or may not necessary.  Much will be dependent on your physical examination;  specifically, factors such as the amount of redundant skin, quality of skin elasticity will be important,  and how much you wish to downsize.
Generally speaking, the best online advice I can give to ladies who are considering revisionary (downsizing) breast augmentation surgery is:
1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or "down 2 cup sizes” or "C or D cup" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate. 
3. Once you feel you have communicated your goals clearly, allow your chosen plastic surgeon to work with you in determining the best plan to achieve your goals.
I hope this helps. Best wishes.
