This is a tough one! In reading the other posts I ran across “ you can put off treatment if you want to.” That is a pretty standard answer when your symptoms are shortness of breath and extreme fatigue. Add loss of 18%body weight for me. The bottom line is that treatment is inevitable. If you wait - maybe - just maybe there will be a less toxic treatment. The reason many doctors leave treatment up to the patient is because the treatment is grueling for most. I have been on it three times and always have to be taken off the meds. Some people are able to tolerate them. Good luck with your decision.
