Please arrive at least 20 minutes before your appointment and bring your referral. If you need to reschedule or cancel, call 24 hours in advance. Tell us if you are or may be pregnant or are breastfeeding. Please bring any previous mammograms and reports to your appointment. Let us know if you have breast implants. If you have had a breast biopsy, please tell us. To minimize your discomfort, schedule your exam 2 to 3 days after the end of your period when your breasts will be less tender. Do not wear perfume, powder, deodorant, or lotions that contain glitter on the breast or underarm area.
