Hi and Welcome
I was diagnosed in March, surgery in April, chemo started in May. I'm stage 3C and on Folfox. Started out every 2 weeks but now every 3 weeks because my WBC was affected badly. I'm on Neulasta for that and doing quite well. I am to have 12 treatments. 7 down and 5 more to go. Number 7 was the easiest one yet. The only time I had diarrhea was with the first treatment. I've had only a few mouth sores, and very little nausea. Treatment #2 was followed by a lot of fatigue. I'm 62 and retired but go about doing my normal daily routine. I live on a farm and have lots of animals. The doc told me I cannot clean out horse stalls

I have changed my diet.... no white refined sugar, no white flour or greasy foods.. I'm eating healthier than I ever have in my life and I think that has helped me a lot too.
I hope your Dad will do fine.
