Please give more information about her specific location in Minnesota, age and medical history if you are able. Some of us actually live here!
Moreover, we may be able to help her ourselves or know of individuals, groups and organizations close to her who can be of help. There are resources.
While it's extremely uncomfortable to say, what concerns me most is that she's isolated herself and gone against medical advice - as if she's preparing to die. That is her choice, (which those who care want to ensure it is a well-informed one) but even so, there are resources that can help with that process of dying.
My apologies for my directness - that's what I gather from the limited information given. I'm sorry for the whole situation.
Yes, we need more information to be of help.
For the record, I myself am a survivor of colon cancer and chemotherapy - I'm 50 months post surgery, I'm proof there is hope - especially if the cancer has not spread elsewhere.
Once again, sorry about your friend.
I know you mean well, but divulging someone's medical history without their permission seems like a very bad idea.
It may in fact be a violation of HIPAA.
