    It has been proved that substantial sub bundle therapy is an effective and latest form of cancer treatment It's a precise radiotherapy that uses proton beams to lock in and destroy cancer cells Compared with traditional cancer treatment methods such as surgery, chemotherapy and X-ray radiotherapy, it is more accurate and effective It can destroy cancer cells without damaging healthy cells Therefore, compared with traditional cancer therapy, it has less side effects Proton beam therapy for cancer was first used in 1954 But because there were very few cancer treatment centers at that time, the application of this therapy was very limited The clapterbridge cancer center in the UK was the first proton beam treatment center, followed by lomarenda medical center in California, USA, which also established one in 1990 In the course of treatment, ionized particles or protons lock the tumor These protons are produced and accelerated by a device called a cyclotron The proton beam penetrates the body at the lowest concentration and reaches the highest concentration once the target cell is locked in The mass of protons is large, so they are not scattered, only for tumors Radiation can destroy the DNA of cancer cells without damaging nearby cells, while chemotherapy can destroy the DNA along with surrounding non cancer cells DNA destruction destroys the ability of cells to proliferate or divide, thus affecting the growth of cancer cells Cells can form enzymes that help repair damaged DNA, but cancer cells lose the ability to produce these enzymes This leads to permanent damage to these cells and eventually death Since the surrounding cells are not damaged during the treatment, the side effects of proton beam therapy are much smaller than that of traditional therapy Depending on the size of the tumor, the duration of treatment varies from a few days to a few weeks If the tumor does not recur within five years of treatment, it is successful The advantages of this treatment over traditional forms of cancer treatment include: there are not many cancer treatment centers providing this treatment, and efforts are being made to benefit more cancer patients The goal of this treatment is to provide patients with more effective tumor control, less complications and side effects, and to improve the quality of life after treatment.
