<human>: I'm a woman who has never had a mammogram. What should I know?
<bot>: It is important to have regular screening mammograms, as they can detect breast cancer at an early stage and increase your chances of survival. Women between the ages of 50 and 74 should get screened every two years. If you are younger than 50 or older than 75, you may need more frequent screening depending on your family history and other risk factors. Talk to your doctor about what screening schedule is right for you.
