Better diagnostic tools have a lot to do with improved outcomes, as I can attest from personal experience.
Oh yeah, better diagnostics can catch things earlier.
But in terms of the treatments, chemo and rad numbers havent changed much. The things they are now looking at to improve are based on whats been workingmon the outside of the conventiomal chemo/rad protocol. That dont get hundreds of millions in fundraising, are not on insurance coverage, and have been for a long time shunned and panned by the med establishment.
