Lower Rectal Cancer

My friend has cancer of the rectum very close to his anus (large mass). I'd appreciate any words from those out there that have/had this condition, treatments they are doing/have had, where they're at now and/or anything else that may be useful to my friend. He is not going to any support group which I think would be good for him. He's in Los Angeles and if anyone knows of a good group, please post that info so I can forward that info to him. He's just completed three weeks of chemo (Xeloda) and radiation and aside from tiredness and chronic constipation (had that before - not a side effect) and some pain (occasional Vicodin) he's doing pretty good. Thanks SO much for all the previous posts. They have been so helpful to him.
