Yes, I agree with ladyboom. You were wise coming to this site. I wish I would have known about it when my journey began in October. All I kept reading was discouraging prognosis, but after finding this site you hear more success stories. Good luck with your journey. I can attest that it's a difficult and very stressful journey, but we must ride the waves that come our way.
One suggestion I have is to get a 2nd opinion. You need to feel very comfortable with your treatment plan and know what your options are. We found that doctors don't tell you too much about syptoms because everyone is different and they don't want to scare you, but if you and your wife are the type of people that like to know all the facts, you should get them from your doctor. We have found that out the hard way.
Also, make sure she starts on Ensure, Boost, or the Carnation (Very High Calorie) drinks early in the process. I've had a terrible time having my husband drink them although he knows he should. They really help with your weight and give you the protetin that your body needs for stamina.
If you have any questions, don't hesitate to post them because you will find that others have also had to deal with that same issue.
Best of luck to you and your wife.
