Re: stage 4 cancer, no treatment...what to expect
I think it depends on where the primary cancer started. Some are faster than others. Even if the cancer has spread everywhere the primary cancer is still the cancer that is being dealt with. Melanoma, pancreas & some lung cancers are known to be much faster than other cancers.
I'm so sorry your friend is dealing with this, but at a certain point it's quality of life rather than remaining time I expect & comes down to personal choice. I'm not sure what I'd do faced with such news......
