After reading the article two things came to mind.
If she did have pancreatic cancer in Dec 2023, the chances of her still being alive today are slim. If the cancer had spread the 5 year survival rate is
really low.
Pancreatic Cancer Prognosis & Survival - Pancreatica.org
Could the diagnosis be inaccurate? If she had other issues (i.e. dementia) could the foster child/caregiver have lied about the cancer to isolate her from other family for reasons unknown, perhaps monetary? I can't see a "caregiver" who may or may not even be trained providing pallative care to someone with pancreatic cancer. Pain management could require morphine based painkiller which would have to be obtained through a doctor/nurse practitioner, and nerve pain (more common on pancreatic cancer) would require amitriptyline and gabapentin, substances I don't see a possibly untrained home health aid dispensing.
A lot of red flags for this one for me personally.
