Proton Therapy

In principle, radiation and proton radiation of standard cancer was same. Both of them relied on the process of 'ionisation' that changed the characteristics of the atom in the molecule of the cancer cell. All of our body parts consisted of molecules that consisted of the atom..Each atom had the core of the atom that was surrounded by the electron.If the proton that had the mass and energy that were high beyond the atom, the proton will pull the electron left his orbit, this process was known as 'ionisation'.
As a result, the characteristics of this atom will change.
In line with that, the place molecule of this atom was will change his characteristics.
The process of the change in these characteristics that it was hoped happened because of resulting in destruction of the DNA composition and very material genetic to cancer cells.
Further, DNA the broken cell made the cell not have a function of, especially dividing and spreading.
Because the capacity improved the low cancer cell although being helped with the enzyme, the process continue this resulted in the broken cancer cell permanently.

In the meantime, with standard radiation, his side-effect was healthy cells in and around the cancer cell will be broken.
This happened because of energy of light radiation could not be focused to the certain area, but was spread to around the area of the illness.
The lack of radiation was with these photons caused precisely by the natural characteristics of the particle of the compiler of the light, photons, that did not have the mass and this cargo.
Energy that was brought by photons will be easy to be absorbed by the medium round the cancer cell personally.
The matter above did not happen to proton radiation.
Because the proton had the mass that was far more difficult than the electron mass and positive electricity cargo, energy that was brought by the proton could be speed up in such a way as the medium could not round cancer absorb energy that was brought by the bundle of the proton.
As a result, the bundle of the proton could be arranged to be able to invest his energy to the location of the cancer cell that purpose.
Proton radiation will be increasingly effective results at this time because of information of three dimensions of the cancer cell could be received with imaging process used the equipment like the PAINT scan.
With this information, the distribution of energy of three dimensions that were needed to deposit proton energy could be obtained.
This will more facilitate the dose regulation of proton radiation that was more comprehensive for a cancer cell characteristically especially.

Although the age of the research of proton therapy has for centuries, the cancer kind that could be treated with new proton therapy cancer that still in the early stage and did not yet spread to the other body part.
Enough cancer kinds that succeeded in being treated with this therapy.
Including being prostate cancer and cancer to children.
Prostate cancer was cancer that attacked the prostate gland that was gotten in the system of the man's reproduction.
Usually happened to the man aged continued, but sometimes also to the young man.
In the USA, the number of sufferers of kind cancer was relatively high, achieved the figure 220.
000 during 2003.
Now in Asia this figure was far more lower, around 10 percent of the figure in the USA.
One of the choices of medical treatment for prostate cancer was with radiation.
This medical treatment most more did not become the choice than the appointment operation of cancer.
Unfortunately, not all the cancer parts were covered with conventional radiation.
So, the best choice was with proton radiation.
In the Hospital of Loma Linda, the USA, personally more than 900 patients from 1991 to 1996 underwent this radiation with very satisfactory results.

In the meantime, cancer medical treatment to children with conventional radiation will endanger healthy cells round the cancer cell, that definitely relative aged young.
Medical treatment with proton therapy helped the doctor to treat only cancer cells and to not increase the risk of destruction of healthy cells.
The child's cancer that was treated with this therapy including cancer to the brain and the eyes.
Because of the development cost of facilities of proton therapy was still relative very expensive, only developed countries that had these facilities.
All over the world at this time only was gotten by 20 facilities.
In several European countries and the USA, apart from developing facilities of proton therapy that completely just, facilities to faster the particle that was finished the period with him for the research of particle physics was shifted by his function to the place of medical treatment with proton radiation.
Swiss with Paul Scherrer Institute and Canada with TRIUMF specialised with medical treatment of eyes cancer.
Germany had several facilities, among them in the Muenchen city, Berlin, and Heidelberg.
In the meantime, the USA had three centre of proton therapy, respectively in Loma Linda California, Boston Massachusetts, and in Bloomington Indiana.
