Mammograms are used to diagnose breast problems. Self breast examinations and breast checks from your provider are two of the best ways to detect breast cancer.
The American Congress of Obstetrics & Gynecology recommends screenings start at the age of 40 (unless advised otherwise by your provider). Afterwards, yearly mammograms are recommended.
Do not wear powders, lotions or deodorants when having a mammogram. These products could show a suspicious area when the mammogram is being interpreted. OBGYN provides deodorant to be used after your mammogram.
