As others in this thread have illuminated, cancer can be cured. But you must change all the things that led your cells to rebel in the first place. You must change.
If I were in your described situation I would sell that farm and move somewhere more hospitable. North Carolina, Hawaii, Mexico(take the cure), Costa Rica, a healing community in California or Tennessee.
Get your women to work on investigating how to get you the REST you need. The fatigue is a message.
I wish you the very best. Peace.
