I had a wife that worked, short term disability, and great insurance. I was able to work 6 weeks after surgery first round and used up all 6 months second time.
I stayed in a room provided my the American Cancer Society for 6 weeks in chemo, no motels or daily commute.
The hospitals have social service programs to help those that need financial assistance.
My kids were grown, my bills were few, and my travel was limited. It was not a burden for me.
We have a guy at work in late thirties, wife fighting terminal brain cancer. He comes in when he does not have to take care of kids from lack of sitter and works. From the office, he looks like a normal guy. But, he is going thru hell keeping it all together.
