**Study Purpose:** This study aims to see if using RADIESSE® (a type of cosmetic filler) in the *décolleté* (the upper chest area) affects the quality of x-rays and ultrasounds of the breast. **Key Points:** - **Participation Requirements:** Must want to improve moderate to severe wrinkles in the décolleté and be willing to have up to three mammograms and four ultrasounds. - **Exclusion Criteria:** Cannot have serious breast diseases, a history of breast cancer, or any recent breast surgeries or treatments. - **Considerations:** Ensure no conditions that make additional radiation risky. **More Details:** Eligible participants should not have any existing breast conditions that could affect the imaging results. Those with a history of breast cancer or certain genetic markers, uncontrolled diseases, or prior surgeries in the breast area are excluded from the study. This study looks at how the cosmetic treatment might interfere with medical imaging tests like x-rays (mammograms) and ultrasounds, which are important for checking breast health.
