5'5", 145lbs. Is 475cc too large? (Photo)

Hello and thank you for your question. You are a great candidate
for a breast augmentation.   In order to determine if 475cc would be a good size for you, it would be helpful to know your individual breast measurements.  The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.  This entire surgery
can be performed with a small incision technique.  Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.   The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

It is very difficult without assessing you in person to know if the implant sizes you mentioned will be a good size for you. Keep in mind that implant size selection not only depends on your personal preference, but it also depends on your unique measurements. There are various types of implants that can help you attain the look you are going for. A thorough consultation with a board certified plastic surgeon will allow you to communicate what your desired result is and will inform you as to what is possible to achieve your goals. We have a device called the Vectra 3D imaging system that shows you what you will look like with any implant. Our patients are very happy with the choice of implant they make when using this system. To learn more about breast augmentation, you can read “A Comprehensive Guide to Breast Augmentation.”

Thank you for the question. 
 Based on your photograph, I think that you are starting at a good place and should have a very nice outcome with breast augmentation surgery.


There are several steps taken to select a specific size/profile breast implant for a specific patient. These steps will vary from one practice to another.  I prefer to have a wide selection of implants (all profiles) available in the operating room. I use intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison. I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible. 


Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures, direct examination/communication in front of a full-length mirror, in bra sizers, and computer imaging) as well as careful measurements (dimensional planning) will be critical.


Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) 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. For example, I have found that the use of words such as “natural” 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 him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.


3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.


***In your case, my best advice: more communication. It will definitely worth spending more time (prior to the date of surgery) with your plastic surgeon to discuss further.  As you know, it will be important for many reasons, that you feel comfortable that you and your plastic surgeon are on the "same page" prior to proceeding.
I hope this helps. Best wishes for an outcome that you will be very pleased with.
