(HealthDay News) -- A mammogram is an X-ray of the breasts that's designed to detect abnormalities, including possible tumors.

Doctors may compare a current mammogram with past results to learn of any changes.

The National Women's Health Information Center offers these suggestions to help women prepare for a mammogram:

• Don't schedule a mammogram for the week just before your period, as your breasts may be swollen and sore.
• Let the technician know before the test begins if you have breast implants.
• Wear a skirt or pants with a top that's easy to take off. You don't have to completely disrobe.
• The day of the test, skip applying any lotion, powder, perfume or deodorant under your arms or near your chest, as these can affect the results.
• Bring any previous mammogram results with you.
