Does ivermectin ( the stuff in a tube) work for cancer my insurance is refusing to pay for cancer treatments?

I have a huge visible lump on my neck. It is cancerous. my insurance won't cover any of it my treatments and I can't afford to pay out pocket. Does ivermectin the horse dewormer actually work? I am aware it sounds stupid but I am desperate.

It is affecting my teeth and brain. I had to go to a foot Dr last year and my insurance didn't pay it because I had a another insurance I didn't know I signed up for. I have united healthcare.
