Breast implants: what you need to know


Millions of women have breast implants.  First marketed in 1962, they have been regulated by the FDA since 1976 for breast augmentation, reconstruction after breast cancer surgery or trauma, and to correct developmental defects or correct or improve the result of a previous surgery.  Yet, their history has been marked by uncertainties, local complications, claims of systemic health problems and, most recently, cancer.  In 2011, the FDA identified an association between breast implants and the development of anaplastic large cell lymphoma (ALCL) in the fluid or scar tissue surrounding the implant.  At least 457 women in the U.S. have been diagnosed with breast implant-associated ALCL, with almost 700 cases reported worldwide. Sixteen women have died, nine in the U.S.  To address growing concerns, the FDA has recently held new hearings to discuss breast implant safety.  

Two types of breast implants are sold in the United States: saline-filled and silicone gel-filled. Both have a silicone outer shell that can be smooth or textured.   For decades, implants have been blamed by some recipients for a number of health problems including autoimmune/connective tissue diseases, debilitating joint pain, fatigue, myalgias, muscle weakness, sleep disturbances, cognitive impairment, memory loss, and dry mouth – so-called “breast implant illness” (BII).   

Back in 1992, the FDA placed a ban on the use of silicone breast implants outside of FDA-approved research studies.  But after two New England Journal publications in the mid-1990s failed to find an association between implants and connective tissue disorders, and a 400 page report from the Institute of Medicine in 1999 concluded that “although silicone gel breast implants were potentially responsible for such local complications as hardening or scarring of breast tissue, implants did not cause autoimmune disease,” the ban was subsequently lifted in 2006. 

Although studies have failed to provide definitive evidence that silicone breast implants are associated with the development autoimmune or connective tissue disease, some argue that the studies have been inadequate – that they need to be larger and conducted over a longer period of time. There is evidence that the materials in medical implants are capable of producing an immune inflammatory response and may be influenced patient genetics, comorbidities, and lifestyle as well as anatomic location and implant duration.

It’s important to note that breast implants do not last a lifetime and that additional surgeries will likely be necessary.  Local complications include capsular contracture, implant rupture, breast pain, wrinkling, asymmetry, scarring and infection.  Although most patients with ALCL can be treated with breast implant removal alone, some have required radiation therapy, chemotherapy or both.  

Despite the controversy and potential health risks, many women experience improved mental and physical health and quality-of-life following breast implant surgery and most report long-term satisfaction.  It will be important to see what the FDA’s most recent hearings reveal and what the future holds.  At the very least, larger, longer and better-quality studies need to be conducted so that women and their physicians better understand the risks and benefits of this procedure and make a more informed decision.
