<human>: My doctor says that I need to have a mammogram. What should I expect?
<bot>: You should expect to be in the radiology department for about 30 minutes, during which time you will be asked to remove your shirt and bra, put on a gown and lay down on a table. The technician will then take pictures of your breasts with a special machine called a mammography unit. After the procedure is complete, you can get dressed and go home.
