I am so glad that your father is doing well. My mother was very weak too before chemo. Her onc asked us whether we wanted to start her on chemo. I too am glad that she did it. Her response to chemo was good.
Never lose hope. I am very happy for your father. Even though chemo might be part of his life, there is a life to live.
Please keep us udpated on your father's status. God bless!
May
