You will be asked to undress from the waist up. You will be given a gown to wear. Depending on the type of equipment used, you will sit or stand.
One breast at a time is rested on a flat surface that contains the x-ray plate. A device called a compressor will be pressed firmly against the breast. This helps flatten the breast tissue.
The x-ray pictures are taken from several angles. You may be asked to hold your breath as each picture is taken.
You may be asked to come back at a later date for more mammogram images. This does not always mean you have breast cancer. The doctor may simply need to recheck an area that could not be clearly seen on the first test.
Digital mammography is a newer technique. It allows the x-ray image of the breast to be viewed and manipulated on a computer screen. It improves accuracy, but it is not yet available everywhere.
