1. Proton is not an elementary particle but a synthetic particle, which is one of the nucleons inside the atomic nucleus. Proton therapy is suitable for radiation therapy of various benign and malignant tumors, especially for early tumors, the five-year survival rate is up to 80% or more.
2. The difference between the fast sharp knife and the fast sharp knife is that they are both a new technology of radiation therapy, and the guidance technology of stereotactic radiotherapy they adopt is different. Rapid-fire knife is suitable for patients with tumors less than 3cm and avoiding vital organs, which are suitable for receiving rapid-fire knife treatment.
3. Proton therapy is the world's most advanced, precise and effective radiotherapy for many kinds of tumors. Proton therapy is also known as "proton line therapy" and "proton knife", which is the same as "gamma knife" and "TOMO knife" we have heard of. As we have heard of "gamma knife", "TOMO knife", this is not really a "knife", but actually a form of radiation therapy.
4. The difference between proton and heavy ion therapy and conventional radiotherapy, proton can disrupt the single chain of DNA of tumor cells, and heavy ion is even more powerful, it can disrupt the double chain of DNA of tumor cells, thus it can destroy the tumor cells and prevent them from repairing. Especially insensitive to conventional radiation, as well as recurrent tumors can be effectively killed.
5. Proton therapy is a kind of radiation therapy, after the proton enters into the human body, it forms a sharp dosage peak at the end of the range, which is called Bragg peak. The Bragg peak covers the tumor through the modulation of energy spreading, and then combined with the specialized machines and instruments, the irradiation of the tumor is carried out, which finally achieves the purpose of killing the tumor cells.
