Is there a noticeable difference between 405cc moderate classic and 425cc moderate classic?

20cc.  (!!!)Only kidding. I do not think you will be able to tell the difference between the two if they are the same profile (ie both moderate classic). Congrats on your decision and good luck.

The difference in volume of 20cc's is the equivalent of 4 teaspoons. So I don't think you will notice a difference. When my patients are trying to decide between to different sizes, I recommend the larger implant. Good luck!

A 20 mL difference with the same style of implant will not make a significant visual difference.  Generally, if you are between sizes I would recommend you choose the larger of the two.  Good luck 

I tell my patients that if they really want a noticeable difference, then 50-100cc will be visible. I think that a 20 cc difference will be barely visible. If my patients have difficult choosing between 2 sizes then we suggest they choose the larger size, if it is reasonable for their frame. All implants look slightly smaller once they are inside and once the swelling has gone down. In our office we have Crisalix, for 3 D imaging so you can see what you may look like between the two sizes. We even have virtual reality goggles so that you can look down at yourself, to see the switch between the two sizes instantaneously. It is super fun and patients are truly amazed with the goggles. I always get a chuckle out of their responses. Make sure to see a board certified plastic surgeon with lots of experience.

Hello and thank you for your question.  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.
