Different from the X-rays, protons
by the energy setting will afford the maximum energy deposited in the tumor
tissue of the prostate gland, with a relatively very small doses in the small
intestine and urinary bladder. Irradiation from the side with a beam of x 18
MeV, then a lot of energy deposited in the hip bone, while the proton can
deposit energy in the prostate with minimal radiation to normal structures. The
advantage of concentrated dose also occurred in treatment of tumor on the inner
eye, as in ocular melanoma. Treatment with proton very effective and satisfying
as it can save a variety of sensitive tissues of the eye, so the patient's
vision is not impaired. In the conventional treatment for this case is to lift
the patient's eye, which in addition can also resulted in the appearance of
defects of vision loss. This method has a lot of help cure cancer in the brain,
head and neck of the womb.
Therapy with a proton with a unique character in
terms of clinical benefit in cancer control and handling, can contribute
significantly to healing and pain reduction as well as in patients. The
accuracy of this technique can be further enhanced if supported by imaging
techniques, to be able to confirm the volume and position of the target
irradiated want, especially in certain parts such as head and brain. With the
availability of such equipment include X-ray Computed Tomography (CT Scanner) and
Magnetic Resonance Imaging (MRI), the medical experts can calculate the
position and size of the tumors, to conduct a more effective therapy.
With very less damage to healthy
tissue, then the potential for side effects like nausea, dizziness and diarrhea
post-irradiation becomes greatly reduced. By taking as many as 20 fractions of
radiation, patients can undergo irradiation only once a day, 5 times a week, so
for the entire treatment takes one month. It could be said that the cancer with
proton therapy is a new noninvasive way with huge potential.
