How Often To Do Mammogram – Breast cancer screening detects cancer and saves lives. Mammography has been the best tool for a long time. When mammography is combined with digital breast tomosynthesis or DBT (3D mammography), there is a greater chance of detecting cancer, especially in dense breast tissue.
Providers may use two-dimensional mammography or tomosynthesis to screen for breast cancer, but tomosynthesis is better at detecting cancer in dense breast tissue.
How Often To Do Mammogram
Digital breast tomosynthesis (pronounced “toh-moh-SIN-thah-sis”) is a technologically advanced mammogram that excels at detecting breast cancer, especially in dense breast tissue. Breast tomosynthesis is also known as 3D mammography because it uses a series of 2D images to create a 3D image of your breast. Standard mammography, still considered the most reliable method for breast cancer screening, takes two-dimensional images of the breasts.
When Should You Get A Mammogram
The US Food and Drug Administration (FDA) approved digital breast synthesis (DBT) in 2011. Given how well DBT detects cancer, it may eventually become the new gold standard in breast imaging.
Anyone who needs a mammogram can potentially benefit from DBT, but it’s especially helpful if you have dense breast tissue (as opposed to fat). About half of women and people assigned female at birth (AFAB) have dense breasts. The denser your breast tissue, the more difficult it is to detect cancer on a standard 2D mammogram.
Like standard mammograms, DBT uses low-dose x-rays to take pictures of the inside of the breast. Dense (thick or compact) tissue—including bone, solid tumors, and dense breast tissue—absorbs more radiation from X-rays and appears white on a mammogram. Distinguishing between cancer and dense breast tissue can be difficult, as both appear white on imaging.
Digital breast tomosynthesis takes multiple pictures of your breast from more angles than a regular mammogram, creating a more detailed image. DBT shows cancers that may otherwise be “hidden” in dense breast tissue. It correctly identifies normal tissue that may look “suspicious” or potentially cancerous on a standard mammogram. In this way, DBT reduces the frequency of false positives (learning that you might have cancer when you really don’t).
How Often Do You Really Need To Get A Mammogram?
Early detection is key in the diagnosis and treatment of breast cancer. Health care providers use traditional mammography and tomosynthesis (3D mammography) to screen for new lumps or other signs of cancer in breast tissue.
A radiologic or mammography technician will position you for the procedure and operate the mammography machine. The radiologist will analyze the images and share the test results with your referring provider.
Digital breast tomosynthesis (DBT) is similar to standard mammography. The main difference is that it takes more pictures of your chest from more angles to capture more detail.
During a standard mammogram, your breast is placed on a flat support and compressed (compressed) between two horizontal plates. This device takes two-dimensional images of your chest from two angles, top to bottom and side to side.

During DBT, your breast is positioned and compressed in the same way as for a 2D mammogram. However, during breast tomosynthesis, the arm of the mammography machine (X-ray tube) moves in an arc across your breast, taking many 2D images from different angles as it moves.
The 2D images are digitized and fed into a computer that combines them into a 3D image. The 3D image shows more detail and makes it easier to distinguish between healthy and potentially cancerous tissue.
Make sure your health care provider is fully informed about your medical history—especially your breast health. To prepare:
Having a DBT is like having a standard mammogram. The biggest difference is that with DBT, the machine arm (X-ray tube) moves in a slow arc around your chest as it takes X-rays.
What Is A Mammogram And When To Get A Mammogram — Know Your Lemons® For Early Detection
The FDA has approved the use of DBT only in combination with mammography. The total radiation dose is less than three times that of mammography. While three times may seem like a lot, it is still a low radiation dose that is considered a safe amount of radiation exposure.
Newer tomosynthesis techniques can create two-dimensional images from the data used to create the three-dimensional image. This reduces the amount of radiation exposure, so it is only slightly higher than a standard mammogram.
Mammography, including tomosynthesis, uses the lowest and safest possible radiation dose that still produces a high-quality image for breast cancer detection.
The radiologist reviews the images to check for signs of breast cancer. They may compare the 3D image with your previous mammogram results or 2D images if they see a suspicious area. They will prepare a report for your provider, who will share the results with you.
Preparing For A Mammogram: A Step By Step Guide
Depending on the results, you may receive confirmation that you do not have cancer. You may learn that you need additional tests to examine the suspicious tissue more closely. You may need additional mammograms, ultrasounds, MRIs, or biopsies. A biopsy is the only way to confirm a cancer diagnosis.
You will probably get results within a few days, but it may take longer. Before you leave the testing center, ask about how to get your results and how long it will take.
Tomosynthesis creates a more detailed image of your breast than a regular mammogram. It is better in detecting cancer and reducing false positive results in dense breast tissue. However, research into whether 3D mammography is better than 2D mammography in breast cancer screening in general is ongoing.
Follow your healthcare provider’s recommendations for breast imaging procedures based on your medical history and breast tissue.
Mammograms: Make Time For The Test
Yeah. This provides a more detailed image of your breast and makes it easier for the radiologist to detect dense breast tissue and cancer.
If you have dense breast tissue, digital breast tomosynthesis (DBT) may be the best option for detecting breast cancer. If you are going to have a mammogram, ask your doctor if tomosynthesis is part of the procedure. Depending on your health, a standard mammogram may be enough to detect breast cancer. In some cases, tomosynthesis may be more likely to detect cancer or to rule out false positives. Don’t hesitate to ask for details about the method, including why it is (or isn’t) right for you.

Breast Cancer Risks: Density Risk Factors
Breast cancer is the most common cancer (other than skin cancer) among American women. 1 out of every 8 women will get breast cancer at the age of 75. For the average woman, there is about a 12 percent lifetime risk. However, if detected early, when the cancer is localized (has not spread outside the breast), the 5-year relative survival rate for breast cancer is 99%. This means that women diagnosed at this stage are 99% more likely to live at least 5 years than women who do not have breast cancer. I’d like to discuss how and when to start breast cancer screening and if the results don’t come back as “normal,” we’ll be called back for more imaging. With our new mammography suite in St.
Fortunately, mammography is the primary screening tool we use to check for breast cancer in women who have no signs or symptoms. Mammography uses a small amount of radiation (X-ray) to give us a view of the breast.
The goal of mammography is to reduce breast cancer mortality by early detection of the disease at a time when treatment is more effective and less harmful. The risk of dying from breast cancer is reduced by 30-48% with routine mammography screening.
The American College of Obstetrics and Gynecology and the American College of Radiology recommend annual screening mammography starting at age 40. Breast cancer grows faster in women in their 40s and early 50s.
Common Mammogram Myths — Debunked
A family history of breast cancer means you may start screening earlier. For women with a first-degree relative with breast cancer (mother or sister), mammography screening should begin ten years before your relative’s age at diagnosis. For women who carry BRCA-1 or BRCA-2 gene mutations (the most common cause of hereditary breast cancer), annual mammograms should begin at age 25. Breast MRI may also be used to screen women who carry the BRCA gene mutation.
Women (or girls) who were exposed to chest radiation before age 40 (perhaps to treat another cancer) should begin screening mammography and consider a breast screening MRI eight years after radiation therapy.
Of the 100 women who get their annual screening mammogram, 90 are told everything looks normal. Ten will be “read back” for further evaluation (additional mammography screenings and often ultrasound).
