Thanks a lot for your detailed response, sir. This is important and valuable information, as we prepare my father for Tomotherapy radiation. Tomotherapy doesn't seem to be a common choice in the western world.

It has been a highly emotional, obsessive researching weeks/months for the family, now we seem to have some level of acceptance, some direction.
Might bother you more at a later point in time. Meanwhile, as you said, we will learn to live each day with more joy, affection and with a smile! Take care.
PS: This is a great forum, of support, of inspiration! Keep fighting, keep smiling everyone!

God bless.
