Cancer advice

A family member has just been diagnosed with bowel cancer. They will need chemo and radiotherapy at least but we don't know the treatment plan yet.

Are there any self help book or websites I can suggest they read? They are interested in altering their diet, supplements etc... anything really that could help or help with side effect of treatment and potential hair loss.

Also is there counselling available for this person and their immediate family members. It's been a real shock. I think seeing a dietitian might also be good it this service available too?

Thanks
