Hi, When I had radiation I was offered physio, OT, dietitian, social worker etc by the nurse the first time I went. I did see the social worker (I had non breast cancer problems) and she put me onto community services for someone who does things like domestic help, help taking me shopping etc. The companies who do these sorts of things often have waiting lists and don't always have the resources to help, but they are there for those in need.
I'd suggest if you need domestic help talk to a social worker.
