Hi Susan & welcome! Your Dad has a way to go. I had about 38 radiation treatments & 4 chemo. The 4th-5th week of radiation is when you start feeling really bad. 21 days after the 1st chemo, my hair started falling out (not a real lot) I wish I could tell you that treatment is a walk in the park...but it just isn't. This is a tough cancer. He IS going to feel very, very tired. I wish he wasn't starting Tx w/ a fever? That worries me a little as a fever is a warning of an infection...but again, I'm NO doctor. I also got the peg, I'm glad I did because after 4 weeks my mouth was so sore, I couldn't eat anything. I also had a "medi-port" put in. It is a central spot were blood can be drawn (in place of always finding veins for IV etc) Mine stayed in for almost 2 yrs. Don't worry about either the peg or if he gets the medi-port "procedure" as it is not so bad & the benefits are worth it. This is enough for you to digest for now! You (both) have a long road ahead of you, just take comfort in the fact...you are not alone. You "Post" as often as you need w/any ???? you have. This site is filled with the best new friends you could hope for ! You sound like a very devoted daughter & your Dad is blessed to have you. Stay in touch!
