November 13, 2019 - U.K. - Clinical Perspectives: A Blood Test to Detect Breast Cancer Could Be Just 5 Years Away
- Cancer researchers compared blood samples from 90 breast cancer patients to 90 patients without the disease, specifically testing for patients’ immune response to substances made by tumor cells.
- The next step is to test samples from 800 patients to improve the test’s accuracy. Further development is needed to validate this test.
- Benefits of a blood test for early breast cancer detection include lower cost, usefulness in low-income countries, and ease of screening compared to current breast cancer screening methods like mammography.
- Breast cancer is a heavy burden, and accounts for 15% of all cancer deaths among women. The WHO says that over 2 million women are diagnosed with breast cancer every year.
Note: Despite this promising research development, mammography is still the current recommendation for breast cancer screening. The American College of Obstetricians and Gynecologists recommends that women without a family history of breast or ovarian cancer get mammograms every 1-2 years starting at age 40.
