My mom was not in pain when she died. I asked her, countless times, and trust me, she would have told me.
The nurses all told me that pancreatic cancer is extremely painful. My mom did not exhibit that pain at all. She cried out once, when her sheets were being changed, because she was so thin and the movement hurt her. But she was okay after a minute. She never asked for morphine.
So although everything looked like cancer, I can't say for sure.
Maybe the Lord spared her that pain.
