Sorry for your loss, I feel your pain. Your wife was very brave to give it a shot and take the fight to the limit, and you should remember her courage and honor her memory and keep fighting till the end regardless of what hardships you encounter in life.
The treatment actually killed my dad. I may be wrong but it appears with the treatment there was a 30% chance of some recovery, 40% chance that it would at least stop the cancer growth, 30% chance that it had no impact. I guess you have to take that chance when you have no other option. I don't blame the hospital (which was terrible) or the treatment, it was the last card left. And our loved ones end up in the 30% statistic and maybe as another anecdote for the risks section, but we know what we they went through and we won't forget.
It was tough because my dad was suffering, but he still was active and had at least a few months left without the treatment and I know that at that point in his battle he did this treatment to keep fighting for us rather than for him, even though it was he who had to suffer through it. So I am going to honor his memory and keep fighting until the end as well.
Thank you both for sharing.
