I am sorry to hear of your loss. My sister in law was diagnosed with stage 4 pancreatic canceer that has spread to her liver, lungs and spleen. I hate this cancer! she has lost about 5 1/2 stone but is fighting. She is having chemo and they say it is shrinking. I have no idea what this means and feeling confused as she is in agony some day :(. I hop you find a way through this. I do have an idea what you are going through and I too feel your anger.

Yes, it's awful. I'm not a medic but know that cancer cannot be cured, in some cases, because it is just so chaotic in nature. It starts from a single mutation, which is essentially random. Then as it spreads it continues to mutate. Which makes it really hard to treat with chemo. Every single cell has to be eliminated. Not easy if all the cells are mutating chaotically, making them all different to one another. We know much more about cancer, compared to forty years ago. But this has given us the knowledge that, as a foe, it is much tougher adversary than anyone could have imagined forty years ago.

Pancreatic cancer is particularly deadly because symptoms often only start late. So when it is diagnosed, it has often spread.

There have been success stories. With most forms of testicular cancer, for example, or many childhood leukaemias. These were deadly forty years ago, but will usually be cured today. But this did not help your poor cousin, of course.
