I love that you called this out. Language matters and can be uplifting or demoralizing. Even when somebody tries to be uplifting it can be demoralizing, as in this scenario. As you said, there is no fight with cancer; undergoing treatment is a chemistry/physics experiment where, hopefully, one comes out of it with no cancer remaining and the ability to heal from the brutally difficult experiment that killed the cancer.

I wish you well and hope you keep on enduring!
