Simple blood test can predict which breast cancer treatment will work best, study finds - The Guardian

A simple blood test can predict which breast cancer treatment will be most effective, according to a study reported by The Guardian. The ASCO Post notes that ctDNA positivity after neoadjuvant T-DM1 may indicate the likelihood of recurrence in HER2-positive breast cancer. Additionally, Oncodaily highlights ctDNA as a key predictor in advanced breast cancer, while the Institute of Cancer Research (ICR) confirms that the blood test can forecast treatment response.
