Hi my brother was diagnosed with stage 4 liver cancer in 2019 and died 6mths later. It was a massive shock as my brother down played it. My Dad then got Esophagus cancer, had surgery and treatment and 4 years later is still here. His cancer returned 2023 and he was told it was inoperable. But he had treatment. Unfortunately it made him feel so terrible, he stopped the treatment. He looks ill, he's in pain, falls asleep as he's so tired all the time and gets periods of terrible nausea. He also doesn't eat at the moment. I'm really worried about him but am in the dark, like I was with my brother, as my dad does not want me to know the full extent of his illness. Anyone experienced in these things? Is it usual for one cancer to kill in 6mths and another to be inoperable but living for 4 years? Also, does cancer with treatment stopped make you nauseous and not eat, fall asleep and in pain? Also, he said something really weird yesterday and I thought he had a little dementia, like he forgot who I was, is that normal? Just want some answers.
