(((Twink))) I'm so sorry to hear what your dad is facing. When I heard about the lump in the armpit...I wondered if it might possibly be hodgkins or non-hodgkins. 3 of my friends have had one or the other of those.
But, it sounds like both of you are feeling much better today and that's good to hear.
You're so special. Holding you and your dad close to my heart.
