Part 3 of “Getting To The Bottom of Cancer!”, our survey of oncological diagnostics! Episode 1 in this series focused on the history of cancer in recorded history, and now Mickey Urdea gets to move on to the wide panoply of tests and technologies that exist today for the screening, diagnosis, staging, prognostication, therapy selection, monitoring, and recurrence of cancer. Part 2 highlighted those technologies focused on the whole body and specific tissue samples, and now Part 3 zeroes in on individual molecules and “the in-between.”
