Radiation Doses and Timing
The dosage and timing of radiation therapy are
critical. It takes medical expertise to calculate
the exact doses that will control the tumour without
causing overwhelming health problems in the future.
If chemotherapy is part of the regimen, it may be
necessary to alter the dose because some drugs can
positively or negatively enhance the effect of the
radiation.
The doctor who plans the timing, duration, site, aim
and dose of radiation treatment is called a
radiation oncologist or radiotherapist. Therapy is
usually given on a daily basis, perhaps five times a
week, over several weeks until the total dose is
delivered. |
