Biopsy alternative

Posted:

Scientists at Stanford University are studying an alternative to biopsy.  And it may someday help diagnose cancers far more easily and effectively.  The research involves using a special machine to analyze a drop of blood or a microscopic piece of tissue to find cancer-related proteins.  Just by watching how a protein changes, scientists say they can figure out if a patient is responding to treatment.  So far -- they've had success identifying cancers of the blood in lab mice and even a small number of human patients.
