Contrary to popular belief and their own feeling of self-importance, lots of doctors are mediocre jerks. I'm glad you did switch and found one that takes his profession and patients serious. Every cancer has a chance of recurrance, that's just something we all have to live with, but getting scared out of your wits shouldn't be part of the treatment.
Hang in thre with the chemo treatment, it's a doozey to have to go through, but if you go and imagine the beating the cancer cells are taking every time, it makes it worthwhile. At least it helped me but then, I'm sometimes a little out in left field anyway.
