Chemotherapy - a Victorian novel in reverse? What do you think?

I think I have the perfect analogy for chemotherapy:
Chemotherapy is like a Victorian novel in reverse:
In the Victorian novel, the killer poisons the victim little by little, so the victim gets sicker and sicker. The doctor is perplexed and goes away, and the patient dies, apparently of natural causes.
In chemotherapy, the doctor poisons the victim little by little so the victim gets sicker and sicker. The killer (cancer) is perplexed and goes away, the patient lives, hopefully for his or her natural lifetime.
