Is mammogram safe in women?

During a mammogram, a radiographer places the breast between two plates and compresses it for a short time. Compression spreads the tissue and helps the machine capture a useful image. It can be uncomfortable, but it should not be unbearable; speak up if you need the position changed. The scan does not use an injection. The radiation dose is low, and the decision to recommend imaging weighs that exposure against the value of checking breast tissue for changes that may not be felt.

Tell the imaging team if you are pregnant or might be pregnant, are breastfeeding, have breast implants, or have had breast surgery. If your breasts are often sore, arranging the appointment when they are less tender may make compression easier. Do not use deodorant, powder, or lotion on your breasts or underarms on the day. Wear clothing that can be removed from the waist up. Bring earlier breast images if the centre asks for them, and tell the radiographer about a new symptom so the area can be considered during the examination.

Arrange medical assessment for a new lump, a persistent one-sided change, bloody nipple discharge, skin puckering, or a newly inverted nipple. A screening mammogram is not a substitute for assessment of a symptom. Seek urgent care for severe chest pain, marked breathlessness, or collapse, regardless of whether you have had imaging.

Why is mammography recommended for me? What should I expect from compression? Should a symptom be assessed before routine imaging?
