Finally, in , dedicated mammography units became available for use around the world. As technology advanced, digital imaging became the preferred method of breast imaging. In the year , the FDA approved the first digital mammography unit, followed 11 years later by the approval of the first Hologic 3D breast imaging technology which quickly proved superior to digital imaging.
Also known as digital breast tomosynthesis, this new 3D technology takes multiple images of each breast, allowing the radiologist to view the breast layer-by-layer rather than viewing a single flat image. Fine details of the breast tissue were now visible and not hidden by the tissue immediately above or below.
In , a study in the Journal of the American Medical Association JAMA , concluded the addition of tomosynthesis with digital mammography finds significantly more invasive cancers than traditional mammography alone, while reducing the number of women called back for false positive readings. The Future of Breast Imaging Learning about these latest technologies, a person cannot help but ponder the future. What does the horizon hold for breast imaging? Recent areas of concentration include: molecular breast imaging MBI , which specifically looks to address the issue of dense breast tissue imaging, and breast specific gamma imaging BSGI , which targets women with high risk factors who receive negative mammograms.
In early trials , when combining high-risk lesions and cancers in women with negative mammograms and increased risk factors, BSGI detected One day, perhaps we will finally win the war against cancer President Nixon announced we were officially waging in Until that time, it is exciting to know that we have created an arsenal of weapons to identify and fight the enemy living within breast tissue, saving men and women from untimely death.

As mammography became a common screening tool for breast cancer, there were many regulations proposed to control the quality of screening. That act specified imaging and radiation standards for mammography, as well as a protocol that all radiologists had to follow to provide women with most accurate information about their health.
It introduced a scale from zero to five, where one meant that there was no cancer detected, and five meant that cancer was likely present in the breasts. A score of zero meant that no mammogram was completed.
In , the FDA approved digital mammography as a diagnostic tool for breast cancer. Using digital mammography, physicians could more quickly complete a mammogram and expose their patients to lower doses of radiation due to a faster imaging procedure as well as better equipment.
Physicians can view digital mammograms on a computer and can analyze results immediately, rather than waiting for film to develop, which could take several days. After Etta Pisano's study, digital mammography became the norm for many hospitals. In , just nine years after the implementation of digital mammography, the ACS reported that the death rate from breast cancer had decreased by thirty-one percent since its peak in However, many women who got mammograms annually got a false positive mammography result, which meant that the mammography wrongfully showed a cancerous mass.
Many of those women underwent treatments for a cancer they did not have, which resulted in physical and emotional trauma. In , the implementation of digital tomosynthesis or 3D imaging mammography improved the accuracy of mammography.
Digital tomosynthesis imaging uses a lower radiation dose, and enables the user to view breasts in three dimensions, as well as looking at each layer of breast tissue separately instead of the whole breast at once. Tomosynthesis analyzes different layers of the breasts and reduces the number of false positive results. Although approved by the FDA in , digital tomosynthesis is not the standard of breast imaging technology as of To reduce breast cancer mortality, the ACS created guidelines for women of different ages about how often they should receive mammograms.
From the s to , the ACS guidelines changed six times. The guidelines changed often because many women received false positive results after getting annual mammograms for multiple years in a row.
The ACS guidelines as of recommend annual mammograms for women aged forty-five to fifty-four and a mammogram every two years for women aged fifty-five and older. According to the ACS guidelines, do not advise women younger than forty to get mammograms, as that can result in unnecessary radiation exposure. There are also multiple other risks in obtaining regular mammograms. The importance of early detection and targeting breast abnormalities in their early stages cannot be overstated, as it can be vital to the successful treatment of the disease, and long-term survival of patients.
Albert Salomon, a German surgeon, was the first person to study X-rays of breast tissue. His findings confirmed that radiology could distinguish between different strains of cancer a fact that was previously unknown , and discovered how tumors spread. He specifically studied their dispersion through the axillary lymph nodes — the region where three-quarters of all lymph node drainage pools.
Stafford L. Warren, an American radiologist and the pioneer of mammography, revolutionized healthcare when he became the first physician to utilize the imaging technique to detect cancer prior to surgery. Prior to this point, doctors had to perform more invasive surgeries simply to detect diseases that would otherwise go unknown. Mammography — a low dose X-ray exam that yields clear photos of the breasts — excels at detecting breast cancer in its premature stage.
It can even spot ductal carcinoma, abnormal cells in the breast lining which can breed more invasive forms of cancer. Robert Egan is widely recognized for spreading the word about screenings and their benefits.
In a newly published study, Gao and colleagues surveyed breast-imaging radiologists to assess their DBT practice patterns.
