3D mammograms which can spot breast defects better than conventional mammograms are gaining traction. However, there is some usage variation in the US. 3D mammography, also known as DBT, use X-rays along with computer software, creating a representation of the scanned breast. DBT makes it breast anomaly detection as an easier task. However, it doesn’t have wide enough endorsements. Yale researchers analyzed claims from private and Medicare providers. During 2015-17, DBT usage increased to 43% from 13% in screening tests. People with Medicare and private insurance also had similar adoption growth rates. While usage increased in the NE and NW regions, it was lower in SE regions. More white population, higher incomes, and more education meant faster adoption.
Dr. Richman, who works as an Asst. Professor in YSM in New Haven, stated that while DBT’s popularity has increased, the uptake is quite uneven. Some parts of the US use it rarely while others see frequent usage. Although current evidence is of the opinion that DBT could increase detection rates of cancer and decrease false positives, this claim still needs more research for assessing breast cancer mortality rate impact. Richman stated that not much was known about its effect on long-run health among women. Studies are currently underway and better answers are expected in the upcoming years.
There are 2 groups in the US that guide doctors regarding cancer screening. These are the ACS and USPSTF groups. They haven’t yet voted against or in favor of the usage of DBT. However, it is suggested by researchers that DBT is bound to replace 2D mammograms in all aspects and become the new standard. Study author Cary Gross stated that this report showed how new findings in medical fields and the rate of adoption of new procedures can eclipse the ability to understand whether they can help patients live healthier and longer lives.
