  "account": "A new blood test is being tested in a clinical trial that could potentially detect breast cancer as early as Stage I. This test could complement mammograms and provide more information for early detection and treatment. Researchers at USC Norris Comprehensive Cancer Center are investigating whether the blood test can work alongside mammograms to detect the disease earlier. The experimental test looks for microscopic evidence of disease circulating beyond the breast, such as rare cancer-associated cells and tumor-associated large extracellular vesicles (L-EVs). These particles are tiny and can be found in the bloodstream even when the tumor is small. The Phase 1 trial aims to determine the accuracy of the blood test compared to patients' diagnoses. If successful, larger Phase 2 trials could follow, potentially leading to an additional screening option for women facing barriers to mammography, as well as those who have undergone a mastectomy. The blood test is currently investigational and cannot replace mammograms or breast biopsies.",
