Steps such as staying active, maintaining a healthy weight, eating a healthy diet, and limiting alcohol consumption can help reduce your risk, but even the healthiest lifestyle is no guarantee against breast cancer. Major medical associations including the American College of Radiology, the Society for Breast Imaging,[1] and the National Comprehensive Cancer Network[2] recommend annual mammography screening for women who are at least 40 years old and at average risk for breast cancer.


Mammograms enable doctors to detect breast cancer earlier.

Mammography has been shown to lead to early breast cancer detection, enabling doctors to see signs of developing cancer before the patient develops noticeable symptoms. Patients whose cancers are found and treated earlier have a better prognosis than those with late-stage cancers, typically undergoing less invasive treatments experiencing much higher survival rates.[3]


3-D mammography is an important advance in breast imaging.

Also known as breast tomosynthesis, 3-D mammography is associated with increased cancer detection and lower recall rates. A study of more than 450,000 mammograms published in JAMA showed that compared with 2-D digital mammography alone, the addition of tomosynthesis resulted in

  • 15% fewer recalls
  • 29% increase in overall cancer detection
  • 41% increase in detection of invasive cancers[4]

Additionally, 3-D mammography has been found to increase cancer detection in women with dense breasts.[5] This is significant because dense breast tissue is associated with an increased risk of breast cancer and also makes it more difficult to spot developing cancer on a mammogram. The images generated using 3-D mammography allow radiologists to see features that would be obscured by dense tissue on a 2-D mammogram, making it possible to more accurately detect cancer in these patients.


The radiation dose used in mammography is very small.

You may worry about your exposure to radiation during a mammogram. The fact is that a mammogram delivers about the same amount of radiation you absorb from natural environment, through sources such as sunlight and radon, over about seven weeks’ time.[6]


Mammography is quick and easy.

A mammogram involves only a 30-minute appointment, about 15 minutes of which is spent capturing images. Each image takes only a few seconds of compression time. You can resume your normal activities immediately after your appointment. If you’re new to mammography, read our article, "8 Things to Expect at Your First Mammogram."
