Official title

Extended Mortality Follow-Up of Women With Augmentation Mammoplasty

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will examine long-term health effects of cosmetic breast augmentation (enlargement) with silicone gel breast implants. There has been concern for some time about the possible effects of breast implants on the immune system particularly regarding the development of certain connective tissue disorders and on the possibility that implants may interfere with the ability to detect breast cancers. More recently, concerns have been raised regarding the possible cancer-causing effect of the implants themselves. These concerns were heightened by reports that the polyurethane foam coating that envelops the silicone gel in some implants may dissolve and produce a chemical called 2,4,-diamino toluene (TDA), which has been linked to an increased risk of breast and other cancers in rats and mice. To address this issue, this study will gather information from the medical records and a questionnaire survey of approximately 12,000 breast implant patients. The questionnaire will request information on perceived complications of the implants; history of breast examinations and mammograms; frequency of breast self examination; development of diseases (particularly cancers and connective tissue disorders) developed subsequent to the augmentation surgery; potential risk factors for these diseases, such as age at menarche (onset of menstruation), age at first birth, age and type of menopause (natural or due to surgery); history of breast biopsies; immune system and connective tissue disorders; cigarette smoking; alcohol consumption; family medical history, and so forth. To evaluate the results, the information will be compared with the same data on 4,000 women who underwent other plastic surgery procedures, such as rhinoplasty, facelift, liposuction, dermabrasion, eyelifts, and others, from the same practices as the breast augmentation patients. Participants will be recruited for the study from several large reconstructive and plastic surgery practices. Among the breast implant patients, women who have had bilateral breast implants for cosmetic purposes only, and not as breast reconstruction after breast cancer surgery, will be eligible. Women with a history of breast cancer may not participate.
