Obviously, needs to be repeated, subtypes of cancer looked at, responsible agent identified.

May change way transfusions are given ie, how old of blood is transfused for different purposes.

I may have mistitled this thread prematurely ie, older blood increases rate of recurrence vs newer blood decreases rate of recurrence!
