Is 650cc pushing it if I am 5'11, 155 lbs and a small B cup? (Photo)

Hello and thank you for your question.    A 650cc may be too large or just fine for you, but this question, and any other question about your breast augmentation would be best answered during an in-person consultation because proper implant selection involves a number of different issues.  I would first have a detailed discussion with you to clearly define your desired breast outcome goals – this would include not just the size you would like to achieve, but your ideal breast shape.  I would then select the best breast implant for you based on volume of the implant, projection of the implant, contents of the implant (saline vs silicone), shape of the implant (round or anatomic), surface of the implant (I only perform smooth), position of the implant (over or under the pectoralis muscle, skin stretch of your breast (more stretch would require a larger volume to fill, as in your breast), degree of breast sag (which would benefit more from a lift), breast diameter and overall chest circumference, native breast tissue volume, and any history of prior surgery or trauma to the breast.

The next step for you is to seek out a board certified plastic surgeon who specializes in aesthetic plastic surgery.  In your consultation, be sure your surgeon addresses all your concerns and discusses the surgery details including the position and size of the incision used, the type of breast implants available, the risks and benefits of the procedure, recovery time, and post-operative course.  Also, be sure to see plenty of before-and-after pictures in women who have a similar breast appearance to yours, and preferably at different time frames (3 weeks out, 3 months out, etc) to more accurately predict your own surgical outcome. 

And lastly, I think the most important component of the consultation is to establish a good connection with your plastic surgeon.  It’s the connection that allows you to clearly define your desired breast outcome goals, the first step of this whole process. If you don’t feel you have a good connection with your plastic surgeon after your consultation, he/she may not be the best surgeon for you.

In general, taller women can usually accommodate a larger implant unless they have a very petite frame. You don't want to choose an implant that is wider than your natural breast. This will increase your risk of permanent nipple numbness. There are also other breast measurements and dimensions that come into play when determining the ideal size for your frame. So I would listen to your plastic surgeon. They do this for a living! Good luck!

Both sizes are large implants which carry more risks long term, especially with sagging. Your surgeon who has measured and examined you will be the best one to tell you what range of sizes best fits your frame and tissue. Please do not choose an implant that is too large.
