New Blood Test Could Help Detect Early Breast Cancer
On November 11, Israel’s Weizmann Institute of Science reported that an international research team had developed a blood test for breast cancer. In trials involving women with breast cancer and healthy women, it identified early breast cancer with up to 95% accuracy and predicted the risk of recurrence after treatment with 81% accuracy.
On November 11, 2026, Israel’s Weizmann Institute of Science said an international research team had developed a blood test that could detect early breast cancer and help predict patients’ risk of recurrence after treatment. The findings were published in the journal Nature.

The method analyzes chemical markers in the blood to identify minute traces of cancer cell activity. In trials involving women with breast cancer and healthy women, it identified early breast cancer with up to 95% accuracy. This result comes from the trials, and researchers believe the method could point the way toward improved cancer detection.
The researchers also found a small group of particularly dangerous cells within tumors. Even when a tumor appears relatively benign, these cells may survive treatment and cause the cancer to return. Detecting specific markers associated with these cells is how the method assesses recurrence risk.
The research team reported that the method predicted recurrence risk with 81% accuracy. Researchers believe the technology could eventually help doctors identify patients at higher risk and choose more suitable treatments accordingly.
