Looking at a blood test to track heart health during HER2 breast cancer treatment
This trial is checking if a simple blood test (NT-proBNP) can help spot early signs of heart side effects from certain breast cancer treatments (chemotherapy plus HER2 blockers). If successful, it might help doctors adjust treatment sooner to protect your heart.
