I wanted to let everyone know that my Dad is doing pretty well almost a week after the cryotherapy procedure/surgery that he had to treat his kidney cancer. That said, the surgery took more out of him than I, and I believe than he, expected. In the mornings he doesn't have much energy but over the course of the day he becomes stronger and more alert. Today the doctor explained that about 25% of the kidney was affected by the surgery and I was relieved to realize it was such a small fraction of his kidney. He is feeling better but he still gets tired very quickly at times.
