What is ucla proton prostate cancer treatment? We’ll talk about this prostate cancer treatment as belows,which is a very pupular,we need to know more about it. Traditional radiation therapy, three-dimensional conformal and intensity-modulated radiation therapy-based treatment is X-ray radiation to send ionizing radiation. In addition to the x-line, the electrons, protons and neutrons and other particles such as atoms can also be used for radiotherapy. Proton-line external beam radiation therapy Radiation therapy is a form of it, rather than using a proton x ray transfer ionizing radiation.

Proton line can be set to achieve a particular depth of the organization, as well to achieve this pre-set depth, the ionization level increased rapidly, Line by adjusting the proton energy, the ionization energy can be enveloping the entire tumor volume, resulting in tumor cell DNA damage, while maximizing protection of the surrounding normal tissues.

This is also the advantages of proton line, which could be better carried out three-dimensional tumor proper type with adjusting the proton linear energy. In addition, the proton line differs from traditional radiation, so that normal cells have the ability damaged white line repair, and tumor cells succumbed to irreversible damage beyond repair. Currently used proton line treatment for prostate cancer, with few clinical reports in the United States, only a few centers is carrying out this project. Preliminary results indicate that without recurrence rate of PEA is average 80.2%. Foci within the prostate smaller, the greater the probability of exposure, the greater the likelihood of a cure. Proton-line treatment for long-term effect remains to be seen. Before proceeding with a discussion of isotopes and their uses, it is necessary to address a point raised very often, when it is stated that some atoms do have the same numbers of neutrons and protons. In fact, nuclear stability is in part a function of neutron-to-proton ratio. Stable nuclei with low atomic numbers (up to about 20) have approximately the same number of neutrons and protons.
