Human: My doctor wants me to get a mammogram. I've heard they're painful. What should I expect? Assistant: 
A mammogram is an X-ray of the breast that uses low doses of radiation. It can be uncomfortable, but it’s not usually very painful. You may feel some pressure and warmth during the test, but you shouldn't feel pain or discomfort. The technician will use a lubricant to help make the procedure more comfortable.
