A mammogram is a specialized X-ray used for the early detection of changes that may indicate cancer. Proper preparation is important to ensure the best possible image quality, which directly impacts the accuracy of the results. Simple choices regarding clothing and topical products can improve the efficiency and comfort of the appointment. Following these guidelines allows the technologist to capture clear images quickly, reducing the chance of needing a repeat scan.
The Essential Clothing Strategy
The most practical choice for a mammogram is a two-piece outfit, consisting of separate tops and bottoms. You will need to undress from the waist up for imaging, so choosing a blouse paired with trousers or a skirt simplifies the process. This allows you to keep your bottom garments on, preserving comfort during the brief screening. One-piece garments, such as dresses or jumpsuits, require complete removal of the entire outfit. Selecting a loose-fitting top will make the transition into the examination gown smoother.
Accessory and Jewelry Precautions
Any metal accessories worn near the chest or neck must be removed before the mammogram begins, including necklaces, chains, and upper torso piercings. These items are radiopaque, meaning they absorb X-rays and appear as dense, bright white shapes on the final image. The resulting shadows, known as artifacts, can interfere with the radiologist’s ability to interpret the image. Artifacts might obscure a finding or require the technologist to take additional views. It is easiest to leave such jewelry at home to prevent misplacing it during the screening.
Why Topical Products Must Be Avoided
Avoid applying deodorants, antiperspirants, body powders, lotions, or creams to the chest and underarm regions on the day of the exam. This rule is centered on the composition of these topical products, as many contain dense, microscopic metallic particles, most commonly aluminum compounds. When the X-ray penetrates the skin, these particles absorb radiation and appear as tiny white specks on the image, which is problematic because it can mimic the appearance of microcalcifications (small calcium deposits in the breast tissue). While most calcifications are benign, some clustered patterns can be an early sign of cancer. The metallic residue can lead to a false positive reading, making it difficult for the radiologist to distinguish between product residue and actual tissue changes, often necessitating a call-back for additional imaging and causing unnecessary stress and delay; if you forget and apply a product, inform the technologist upon arrival, as most clinics have cleansing wipes available.
