@gaylejean - My husband has not had it yet. Our Allentown LVH Cancer Institute is just preparing rooms to begin giving it. On his visit to his Oncologist last week he told him they expect to have it up and ready for April 2019. I like to be prepared ahead of time to what to look for. Not one for surprises anymore; the past 3 years have been full of shocks and surprises and I've had enough now.
