i would have to say i agree with your concerns marmc - i too would feel it was too much on the system... his immune system has been kicked apart and needs to rebuild - and to continue bombarding it for another year - yowza... i don't know - i may be in the minority but i am of the mindset that the minimal amount needed is the maximum you should take into the system. these are toxic substances being put into the system and it effects the entire system not just the cancer... if he just completed treatment in june, he is not nearly recovered yet from that treatment ... and to then start another round that continues for a year ... i know what my answer would be but you have to make up your own mind but if you are not comfy with it then go with your gutt.
