Future doc, I also do not know if cancer cells would be in the blood stream for early cancers but I did read where the test could capture a single cell. The odds of a single cell "anchoring" anywhere may be low but I would think it is likely that any cancer of early stage would shed come cells into the blood stream.
Answer this. Do you think JNJ would pay $51 million for a test that would only detect late stage cancer? About as likely as a snowball in hell.
