Description
Mammograms are x-ray pictures of the breast that check for breast cancer. There are different types of mammograms:
- A baseline mammogram (usually your first mammogram) creates a record of your breast tissue that's compared to all future mammograms.
- A screening mammogram monitors your breast health every year.
- Diagnostic mammograms investigate abnormalities, including symptoms or signs of breast cancer.
Your doctor or other health care provider may order a breast ultrasound after a mammogram to check specific areas of your breast.
