Would you like to participate in Mammography research?

Dr. Paula Gordon and her colleagues are comparing traditional 2D mammography screening combined with tomosynthesis mammography with traditional 2D mammography alone.  The purpose of this study is to compare the recall rate of these two methods.  

The recall rate is the number of women, out of all women that have a screening mammogram, who are asked to return for additional testing due to an abnormal result. Abnormal results do not mean that a cancer was found, but that additional testing is required. More than 95% of women who do need additional testing will ultimately receive a normal result.

Studies have previously compared tomosynthesis mammography to traditional 2D mammography.  Many of these studies showed that tomosynthesis allows for better imaging of the breast, higher breast cancer detection accuracy, and fewer false-positive results than traditional 2D mammography, however the results are not consistent. 

This study will be the first of its kind in Canada to address the existing inconsistent results. This study aims to compare the number of women who are recalled for additional testing from traditional 2D mammography to traditional 2D mammography and tomosynthesis. 

In total, approximately 3000 women will be recruited to participate in this study.  The findings from this study will help determine whether tomosynthesis results in fewer false-positive findings than traditional 2D mammography (the current method of screening for breast cancer in British Columbia).
