Concerns about mammograms for individuals with breast implants are understandable due to the compression involved in the imaging process. While it is a common worry that this pressure could lead to implant rupture, modern mammography techniques and the design of breast implants contribute to an extremely low risk of such an event. This understanding can help alleviate apprehension, allowing individuals to prioritize their breast health.
Understanding Breast Implants and Mammography
Breast implants typically consist of a silicone outer shell filled with either a sterile saline solution or a cohesive silicone gel. Saline implants are inserted empty and then filled, while silicone implants come pre-filled.
Mammography involves compressing the breast between two plates for a brief period to spread out breast tissue, which helps in obtaining clearer images and reducing radiation dose. This compression is essential for visualizing breast tissue effectively and detecting potential abnormalities.
Assessing the Risk of Rupture
The theoretical possibility of breast implant rupture during a mammogram exists, but the actual risk is very low. For instance, a 2022 review of adverse event reports found that out of over 20,500 reported implant-related issues, only 35 (less than 0.17%) were suspected to be caused by mammograms. Both saline and silicone implants have been reported in these rare instances. Factors influencing implant integrity include the implant’s age and type, as older implants may naturally be more susceptible to rupture from any cause. However, the overall consensus from medical organizations like the American Cancer Society is that implant rupture due to mammography is uncommon.
Specialized Mammography Techniques for Implants
Radiologic technologists employ specific techniques when performing mammograms on individuals with breast implants to ensure safety and image quality. Informing the technologist about implants before the procedure is important.
A common adaptation is the use of specialized “Eklund views,” also known as implant displacement views. This technique involves gently pushing the implant back against the chest wall while pulling the breast tissue forward. This maneuver allows for better compression and clearer visualization of natural breast tissue, as the implant is temporarily moved out of the primary imaging field. Additional images are often taken to ensure comprehensive coverage.
Why Screening Remains Essential
Despite concerns about implant rupture, regular mammogram screenings remain an essential tool for early breast cancer detection. The benefits of identifying breast cancer at an early stage, when most treatable, outweigh the minimal risk of implant damage.
Screening guidelines for individuals with breast implants are generally the same as for those without. Individuals with implants should discuss their personal screening schedule and any specific concerns with their healthcare provider. Adherence to recommended screening protocols is important for maintaining breast health.
