Thanks, Karen - for the info - and good to consider when making decisions of Tx as well as preparing questions for the Treatment Group. My son's TX ended five years ago but at the time, when he had 48 lymph nodes removed, I assumed it had something to do the surgeon's being known as very "aggressive" in his treatment. We had not found OCF until after Rad Tx started and had no idea what kind of questions to ask. Things do change, and improvements are made all the time. And, thankfully - we have OCF now, and great people like you to provide help and info!
