Would really need to know the stage of the disease to give in
depth details.
IMRT (intensity modulated radiation therapy) is a form of
radiation therapy where the radiation oncologist can control the
dose to the prostate and surrounding normal healthy tissue. This
control over the radiation is attained by computer controlled
blocking and modulation of the radiation. Since the amount of
radiation can be controlled to areas the are pre specified two
things are achieved:
1. Less radiation effects normal healthy tissue and structures
since there is precise control over the radiation, which in turn
reduces side effects.
2. Higher doses can be given for later stage disease because the
restrictions of the healthy tissue are not present as in reason 1.
