Cancer financial help?

I'm a 38yr old mom, just diagnosied with small intestine cancer, last year had a full hysterectomy due to uteren cancer adencarcinoma to be exact. How do I keep my 7 yr old from losing not just her mom, but, her house "trailer" her home we live on a peice of land that I am probably gonna lose soon due to all these bills! How do I get help?
