Intermittent hormone therapy
for prostate cancer is an attempt to prolong the period
before hormone refractory prostate cancer. Some doctors
believe that administering prostate cancer hormone therapy
for either 6 months on, 6 months off, or only when the
cancer begins to grow again, will keep the cells in
a state where they will be unable to readjust to the
continually changing levels of testosterone. The period
of slowed or halted growth will therefore be longer
before hormone therapy fails.
