Eye cancer and benefits

my husband had cancer in the eye and had to have his eye removed a while ago ,

soon as the eye was removed he was taken of all entitlements .

he became depressed , he wont go out alone , and watching him is upsetting

I thought there was remission period anyway ,

he did try to get a job but no one will take him on anyway as he was told they couldn't insure him , he was a liability

this seemed to make him more depressed

I work 30 hours a week , we may full everything

was just wondering if he could claim anything in his own right
