What is a Mammogram?
A mammogram is a safe, low-dose X-ray that creates detailed images of breast tissue. It is used to look for changes or early signs of cancer that wouldn’t be found during a clinical breast exam or self-breast exam.
Mammograms are the best screening tool for detecting breast cancer early. At Adventist HealthCare, we use advanced 3D mammography technology, which provides a more detailed and accurate view, increasing cancer detection by 30% to 40% compared with traditional 2D mammograms.
When Should I Get My First Mammogram?
For most women at average risk, annual mammogram screening should begin at age 40. If you have a family history of breast cancer, certain genetic changes or other risk factors, your primary care provider may recommend screening earlier. Talk with your provider to understand your risk and when you should begin routine breast cancer screening.
Types of Mammograms
The type of mammogram you get depends on whether you have symptoms. The most common types include:
- Screening mammogram. Recommended each year to look for changes in the breast and detect signs of breast cancer before you have symptoms.
- Diagnostic mammogram. Used if you’re having symptoms or when a screening mammogram or another test shows something that needs a closer look. This allows the radiologist to focus more closely on the specific areas of concern.
Knowing the Risk Factors
There are several factors that can put you at a higher risk for breast cancer, including:
- Genetic mutations, such as BRCA1 and BRCA2
- Having one or more first-degree female relatives diagnosed with premenopausal breast cancer
- Unhealthy lifestyle habits, including poor diet or lack of regular exercise
- Extended hormone exposure due to starting menstrual periods early or experiencing menopause later in life
