So update on my Dad's condition:
He finished his radiation treatments last week and is feeling good. He tires more easily and takes more naps, but he went through both chemo & radiation without any serious side effects other than being tired after each treatment. Took him for his bloodwork on Monday and we are awaiting results. In a week or 2, we'll be taking him for other tests to see if the radiation killed off any cancer cells which had survived the chemo treatments.
I want to thank all of you for your well-wishes and positive thoughts & prayers for my Dad during this very trying time. He & my Mom have been remarkably healthy all their lives but now at 80 & 82, time is catching up with them as it does with all of us. Please continue praying for my Dad that his cancer will be in full remission and he can spend his time gaining back his weight, enjoying his golden years, and spending time with his granddaughters (my girls).
