Thank you, Lynnevb, I appreciate your response and especially, especially the Mayo Clinic protocol for treating ET. Unfortunately, the hematologist I have seen is relatively young and new at her job, and I think she was playing it safe when she wanted me to go on Hydrea immediately, even though my platelets were at 525. I think we each must consider where we are in life and what we want out of life before we make these difficult decisions. Again, because of my age (81 at time of diagnosis), I declined and have remained on the baby aspirin for the last 2-1/2 years.
Wishing you the best.
