Having a breast lift is similar to resetting the clock for sagging. Your breasts will still undergo natural changes due to the aging process, although with proper care you should not experience your previous level of sagging for many years. However, it is important to understand that certain life events, such as future pregnancy or weight fluctuations can negatively affect your results. If you are planning to have more children or you would like to lose weight, it is best to achieve these milestones before having a breast lift.
In 2000, the FDA approved saline breast implant Premarket Approval Applications (PMA) containing the type and rate data of the local medical complications experienced by the breast surgery patients. "Despite complications experienced by some women, the majority of those women still in the Inamed Corporation and Mentor Corporation studies, after three years, reported being satisfied with their implants." The premarket approvals were granted for breast augmentation, for women at least 18 years old, and for women requiring breast reconstruction.
In 1997, the U.S. Department of Health and Human Services (HHS) appointed the Institute of Medicine (IOM) of the U.S. National Academy of Sciences (NAS) to investigate the potential risks of operative and post-operative complications from the emplacement of silicone breast implants. The IOM's review of the safety and efficacy of silicone gel-filled breast implants, reported that the "evidence suggests diseases or conditions, such as connective tissue diseases, cancer, neurological diseases, or other systemic complaints or conditions are no more common in women with breast implants, than in women without implants" subsequent studies and systemic review found no causal link between silicone breast implants and disease.
From your description, you seem to be a very good candidate for this new technique and should really get the look that you are desiring without implants or any unnecessary visible scars. I would recommend that you search for an ABPS board certified plastic surgeon who is also a member of the American Society of Plastic Surgeons and the American Society of Aesthetic Plastic Surgeons in your area or an area that you would like to travel to on holiday who offers the Bellesoma technique to discuss your breast reduction and possible results. You've provided great information - the only thing that would be more helpful in order to give you the best advice about your options would be an in-person exam.
Another option is to consider getting your breast implants at a teaching hospital from a learning resident. You won’t get the delicate skill of an experienced, board-certified surgeon, but teaching hospital residents are “assisted by established, experienced, private attending surgeons,” says Beverly Hills plastic surgeon Dr. Robin T.W. Yuan in a RealSelf Q&A.
