If you have previously had a mammogram done at another clinic, have the results sent or bring them with you to your examination.

Tell your doctor if you:

• Are or might be pregnant. A mammogram is an X-ray test with exposure to low-dose radiation and is not done for routine screening during pregnancy.
• Are breast-feeding. A mammogram may not provide clear results in breasts that contain milk.
• Have breast implants. Breast implants require a modified mammogram method.
• Have previously had a breast biopsy. Knowing the location of scar tissue will help the radiologist read your mammogram accurately.

On the day of the mammogram, do not use any deodorant, perfume, powders, or ointments on your breasts. The residue left on your skin by these substances may interfere with the X-rays.

If you are still having menstrual periods, you may want to have your mammogram done within 2 weeks after your menstrual period ends. The procedure will be more comfortable, especially if your breasts become tender before your period starts.
