There was some very good information about breast augmentation in the November issue of Glamour magazine. I’ve scanned the article so that you can read it. This information should not be your only research, but it’s a good place to start. Most of it is boob job basics, but some of the information was very new. There are lots of pictures that may help you visualize what’s going on with your breasts and implants.
UPDATE: That article is now online here.
