  1. It isn't foolproof and has a high price tag of 950 us dollars. Also gives false negatives and false positives. It's a good starting point but not all cancers are detected by blood tests. For instance I had a thyroid scan and blood work. My blood work detected nothing however the ultrasound detected 3 enlarged suspicious nodules which required a biopsy to futher detect if they were benign or not.
