EGFR Levels Elevated Before Breast Cancer Diagnosis
The study involved 688 women with estrogen receptor-positive breast cancer whose blood was drawn within 17 months prior to their cancer diagnosis. Their blood test results were compared to those of 688 women of similar ages without any sign of cancer.
The findings were presented at the American Association for Cancer Research 101st Annual Meeting.
