I'm a little confused about the difference between a mammogram and a sonogram. Which is best?

The best way to decide which test is right for you is to consult with your doctor or healthcare provider. Both mammograms and sonograms are important diagnostic tools that can help detect breast cancer at an early stage, when treatment is more likely to be successful. Mammograms use X-rays to create images of the breasts, while sonograms use sound waves to create images of the inside of the body.
