First of all, you have my sympathy. I'm a male, age 82, and was dignosed with stage 4 bladder cancer nine months ago. I took immunotherapy for five months, which was quite brutal because I couldn't eat, had to force feed myself, etc. Anyway, I terminated the treatments and am now taking wholistic Fenbendazle (500mg). I quit the immunotherapy six months ago & am now recovering from the immunitherapy treatments, taste buds, neuropathy in my hands and feet. In a nutshell, I believe that the immunotherapy may be good for younger people, but not when in our 80s. Just my humble opinion!
