How Radiation Therapy Works
The photon beam used in radiation treatment is the same kind of beam used
in ordinary chest x-rays or CT scans. However, it has much higher energy
and can cause changes in the nucleus of cells. Both normal tissues and
the tumor tissues will undergo these tiny breaks; however the normal cells
will repair these changes better than tumor cells can. Patients will not
feel the invisible beam passing through them. External Beam Radiation
is a local treatment. It only works where we aim the beam. The radiation
does not circulate through your body and your friends and family are not
exposed to any radiation.
For some cancers, an implant is used to deliver the radiation therapy.
In some gynecologic cancers, a radioactive source is placed within the
vagina or uterus for a short time, to deliver highly localized radiation.
A radioactive source may also be used to focally the cavity left after
lumpectomy to remove a breast cancer.
Adverse effects vary from patient to patient and are determined by the
location of the treatment, the dose required for treatment and the patients’
pre-existing condition. The radiation oncologist, nurse and therapist
will discuss the likely side effects with each patient individually.
Every aspect of the patient’s care is given meticulous attention
to ensure that the patient is treated efficiently and precisely and will
experience the fewest possible side effects. Our physicists, dosimetrists
and radiation therapists conduct daily, weekly and monthly checks on the
department’s equipment to ensure optimum performance. The treatment
team has weekly meetings where every patient’s treatment is reviewed
and discussed in detail.
