MORE: "In the battle against cancer, doctors are finding new ways to use an old weapon: chemotherapy.
The idea behind chemotherapy has long been that more is better. In order to kill the tumor, patients are traditionally given the highest dose they can tolerate. But because the drugs are so toxic, the process must be periodically halted for several weeks to allow the body to recover. Some doctors argue that this resting period can allow a tumor to rebuild the network of blood vessels that it needs to keep growing.
Now, these doctors are experimenting with a new approach, giving very low doses of chemo drugs for extensive periods of time, with no rest."
