NH follicular Lymphoma stage 4

Hello,

My husband was diagnosed with the above on Dec 20th - started RChop chemo on 21st they have said they plan on 6 cycles every 3 weeks - he has growths in tummy, some on right hip and in spine.

We have been told this type is treatable but not curable - just petrified at the fight let alone living with the fear of when it will return.

Is there anyone gone or going through the same that can offer me any help or advice? I feel helpless... 

He is only 35 and we have 2 young children of 2 and 4...
