Blood test findings by Toronto doctors can detect cancerous tumour before it develops::Doctors at Princess Margaret Cancer Centre and The Hospital for Sick Children are helping detect cancer in some patients before a tumour develops or shows up on a medical scan.
This is just stupid. Most tumours arent deadky, especially those found early.
