Development of proton heavy ion in tumor therapy

For malignant tumor, the traditional treatments mainly include surgery, chemotherapy, conventional radiotherapy, etc. Although these treatments play an important role in tumor therapy, however, there are still significant deficiencies: some clinical treatment ineffective, and some serious complications. In order to solve these problems which caused by the above treatment in tumor therapy, domestic and foreign researchers have successfully developed a new treatment—proton heavy ion radiotherapy. The author makes a detailed introduction to the basic principles and clinical application of this treatment method, and provide more information and support for cancer patients and oncologist.
