Dermal filler recently approved by FDA could skew breast imaging results, experts warn
Experts are sounding the alarm on a newly approved use of dermal filler in the décolleté area, citing concerns over its potential effect on breast cancer screening exams.
Radiesse, manufactured by Merz Aesthetics, is a subdermal filler used to smooth wrinkles and decrease the visibility of fine lines. The U.S. Food and Drug Administration on April 8 approved its use for the décolleté area—the upper chest above the breasts—in adults 22 and older.
The filler contains hydroxylapatite microspheres, which may be visible on medical imaging. Given the location of the implant and its close proximity to imaged area, experts are concerned it could affect the visibility of breast tissue on mammograms, masking small lesions. Experts voiced these concerns to the FDA during an advisory meeting about the product last August.
"As a breast imager, my focus is to find a cancer as small as possible," Sandra Shuffett, MD, of Baptist Health Medical Group in Lexington, Kentucky, explained during the panel. "That is my concern, with the fillers potentially obscuring a cancer on a mammogram until it grows larger and then requires more serious treatment."
Merz Aesthetics has refuted these claims, maintaining the safety and efficacy of the product. As a precautionary measure, however, the FDA is requesting that the company conduct a postmarket assessment of 30 individuals to determine whether the filler affects breast imaging. The study will require participants receiving the injections to undergo baseline breast imaging before completing three filler treatments six weeks apart; they will complete additional breast imaging one month after all the treatments have been administered.
In an announcement on the product’s approval, Merz added a disclaimer that it could be seen on X-rays and other medical imaging. The company says that although there is “no evidence of Radiesse injected in the décolleté being visible on mammograms or breast ultrasound,” women should still inform their physicians that they have received the injection.
