My Father was diagnosed with bladder cancer in the muscle wall at age 87. He underwent chemo and radiation. The chemo never produced nausea or hair loss. The cancer metastasized into his lung and finally into his brain. He died at 89. I was surprised that he had no side effects. It made me wonder if he was given bogus chemo drugs, or was seriously under-doped.
Perhaps they gave him a minimal dose due to his age.
