Hi Magsjeanea, I was diagnosed with colorectal cancer in 2010, had rectum and sigmoid colon removed but colon re-attachment to anus was possible. The recovery from surgery was easy, and took about 2 weeks to feel like myself.
4 wks after surgery I started daily chemo and radiation session for 30 days, by week 2 I was bed ridden and trying to cope with lethargy, diarrhea, nausea and vomiting.
Once the radiation treatment stopped I had chemo sessions one day a week for 4 weeks, again I responded badly to new treatment and ended up in hospital more than once.
I am a single mom with two dependents, and I too was stressed about job security and income and was extremely concerned about the future of my family.
I am not sure if the above helps you but please do not try plan and control too much of what could/might happen as each person is unique and their reaction to their treatment is unique.
My lesson was to sit back embrace the treatment, accept the weakness's that come with it and just focus on getting through it. My support during this difficult period came from friends, family and strangers which allowed me to stop stressing about things not going according to the plan.
I would recommend you husband looks at what he can start taking before he starts treatment like folic acid for mouth ulcers, SOLAL - Glutamine for radiation theropy and so on.
Wishing you and your husband all the best during his treatment.
Regards
