What is the advantage of Proton Heavy Ion over conventional radiotherapy?

From the figure, we can see that traditional radiation will gradually weaken as it passes through the human body, and its effect on cancer cells is limited, and the energy is not controllable, so when using traditional radiation to treat patients, it is impossible to avoid damaging normal tissues of the human body. The penetrating power of proton heavy ion is much higher than that of traditional radiation therapy, and the energy is controllable, which can realize the targeted killing of cancer cells.

Compared with traditional radiation, proton heavy ion can release higher radiation to cancer foci, thus achieving better treatment results. At the same time, Proton Heavy Ion Therapy can minimize the damage to normal body tissues caused by high radiation dose irradiation and reduce side effects.

In addition, compared with traditional radiotherapy, PBRT can reduce the burden on the patient's body. Patients who use proton heavy ion radiation therapy will not feel pain, burning, fear, etc. At the same time, proton heavy ion radiation therapy will not leave traces on the patient's body. Therefore, compared with conventional radiation therapy, patients receiving proton heavy ion radiation therapy can return to their normal lives after the treatment is over, which improves their quality of life. In addition, the treatment time for patients undergoing proton reionization radiation therapy is shorter, typically ranging from about 2 weeks to 5 weeks for patients depending on their condition.
