An ideal prescription result in the cancer treatment is what you irradiate the pinpoint with to deari, a cancer cell you "assign the biggest quantity to only a cancer cell, and to expose minimum quantity to to a normal cell", but actually the cancer cell will arrive at the cancer cell including uterine cancer after can go through a normal cell from a thing in the body.
You irradiate it for a cancer cell intensively from the plural positions, and there is the method that is not affected as much as possible, and a normal cell call the method of these with normal position radiotherapy or rajiosajieri, and it is controlled to get the greatest energy in a cancer cell in the case of the medical treatment using the grain.
There are grain medical treatment, gamma knife, cyber knife, X knife akyunaifu, attendant therapy, nova squirrel, four Cal unit in a new method, but there is the ineffective method for the uterine cancer, too, and actually the part is used.
Normal position radiation exposure (Stereotactic irradiation STI) STI has patient fixation and treatment apparatus precision in the range of treatment precision +-2 millimeters, and there is normal position radiation exposure (Stereotactic radiotherapy,:, SRT) you divide stereotactic radiosurgery (Stereotactic radiosurgery,:, SRS) and the precision that irradiate once with several tens Gy in STI by a method you perform a radiation, and to treat without changing it, and to irradiate only the tumor outskirts by you concentrate on it, and irradiating it with a radiation.
Gamma knife was famous for SRS, and in late years similar treatment was enabled with a straight line accelerator.
As for the gamma knife, 201 gamma beam that consisted of hemispheric fixtures in the letter of a thin beam comes to concentrate 201 cobalt-60 on one point to a cancer cell.
You are called gamma knife from what an affected part comes to have cut with a knife.
It was devised as a brain tumor approximately 30 years ago, but in late years got possible to use it for uterine cancer first.
As for intensity modulation radiation therapy (Intesity Modulated Radiotherapy,:, IMRT) STI, irradiation was possible by a radiation intensively, but it was impossible use when the danger internal organs were included in the basics by dose of radioactivity distribution of the addition.
It is the method that it lets strength be irregular by you repeat a small mosaic, and can put the radiations from 1 direction together as well as the shape of the radiation, and can create the low part of the radiation.
It is hereby said that you can anticipate the improvement of the cure rate so far by the decrease of the side effect that evasion was difficult and the increase of the tumor dose of radioactivity.
