We have an army, a navy, an air force, special ops and the marines to fight our battles, and we have some troops, the national guard, the coast guard, and various domestic intelligence agencies, the police, etc. to protect us at home.
Why would you fight an enemy like cancer with just chemotherapy?
Why would you fight an enemy like cancer with just specific immunotherapy?
Or just surgery (even when each tumor cannot be safely cut out)? Or just radiation (even when each tumor cannot be wholly irradiated)?
Why not invoke metabolic weapons, chemical weapons, the knife, radiation, and specific and non-specific immunotherapies?
Are we positively nuts?
