The cancer treatment with proton beam.

25 , in cancer treatment with proton beam , as introduced into the treatment for the first time in the country a state-of-the-art equipment that can be irradiated with pinpoint the affected area , Nagoya proton therapy center in Nagoya was published in the press . I start the treatment from January next year . This is called "spot scanning irradiation " is applied to the affected area of the proton beam 5-15 mm in diameter , to kill cancer cells . Precision irradiation can be , cuts down damage to the normal surrounding cells .A type of radiation therapy , proton therapy to shed cancer cells by accelerating the nuclei of hydrogen . Because unlike such as X-ray , and stops protons proceeds to some extent by the body , it is easy to pick off the cancer cells . However , for applying to the affected area to expand to 14-25 cm in diameter the proton beam in the conventional " broad beam irradiation " , there was a need to create a mold of the affected area so as not to damage the normal tissue .The time being , the center plans to use in the treatment of prostate cancer . Spread also such as bone sarcoma in the future , with the aim of treatment of 800 people per year. It is not recognized as health care , it becomes cost nearly 3 million yen as advanced medical .It might be that it will be good news for those who suffer from cancer .


名古屋市の名古屋陽子線治療センターは２５日、陽子線によるがん治療で、患部をピンポイントで照射できる最先端機器を国内で初めて治療に導入するとして、報道陣に公開した。来年１月から治療を始める。「スポットスキャニング照射」と呼ばれ、直径５～１５ミリの陽子線を患部に当て、がん細胞を死滅させる。精密照射ができ、周辺の正常な細胞の損傷を減らせる。
　陽子線治療は放射線治療の一種で、水素の原子核を加速してがん細胞に当てる。エックス線などと違い、陽子は体内である程度進むと止まるため、がん細胞を狙い撃ちしやすい。ただ、従来の「ブロードビーム照射」では陽子線を直径１４～２５センチに広げて患部に当てるため、正常組織を傷つけないよう患部の型枠を作る必要があった。
　センターは当面、前立腺がんの治療に用いる方針。将来的に骨肉腫などにも広げ、年間８００人の治療を目指す。保健医療と認められておらず、先進医療として３００万円近い費用になる。
　ガンで悩んでいる方にとっては朗報になるのかも知れませんね。
