CHENNAI: Breast cancer may soon be detected in the early stages using a blood test, results of a clinical trial by the Cancer Institute in Adyar have shown. If a larger clinical trial confirms these findings, these blood tests may not just replace mammograms and physical examination, but will also help in early diagnosis and treatment, improving outcome.
The blood test looks for three gene markers in cell-free DNA drawn from the plasma of women, and identifies all stages of cancer, including those in the early stages when confined inside the ducts (non-invasive), scientists said.
