Thank you for your question.Breast augmentation is a very personal and involved decision. There is often a desire to achieve a more "natural" appearance. It is difficult, however, to pin down exactly what "natural" means to each patient and each surgeon. With the use of implants, there will always be a position or activity during which the breasts look augmented, and hence, "unnatural." Which positions and activities those may be will depend largely on the choice of implant (size, profile, silicone vs saline), the technique used (submuscular, subglandular), the approach (periareolar, transaxillary, inframammary), and the expectations of the patient and the surgeon. Many women find that when lying on their backs, the implants are the most obvious - women with naturally large breasts will often say that the breasts will fall to one side or another when lying down, whereas women with augmented breasts state that they tend to stay where they are when lying down.Having said all that, low profile implants do tend to be less obvious, and yield a less "augmented" look.Another option to consider if a modest increase in volume combined with a more natural appearance are desired is a fat transfer augmentation, otherwise known as a "natural breast augmentation." This involves transferring fat from one area of the body (thighs, abdomen, flanks) to the breasts in order to achieve the increase in volume. This procedure has the added advantage of avoiding the potential risks associated with implants, such as capsular contracture and implant rupture, as well as avoiding a larger scar. While this option isn't for everyone, it may be something to consider.I suggest that you speak with your surgeon about your concerns. You may also wish to get a second opinion - you would be well-served by finding a board-certified plastic surgeon who is well-versed in the full range of possibilities so that you can know all your options and make a good, informed decision regarding them.Best wishes.
