1st day of Immunotherapy. When we were told the regimen 4 months ago how my Dad would go through 4-6 rounds of chemo, possible radiation and then immunotherapy maintenance, none of us knew if he would get to this day. Yet here he is, kicking cancer's butt. I am so proud of how he has held up during these 4 months. He's sad he lost his hair (he always is so particular with his hair :) ). That's what makes my Dad my Dad! But hair will come back. He has some bumps but just a few really big potholes. We are blessed for this!
