Proton Beam Therapy and CERN Hadron Technology Are Fighting Cancer With LIGHT

Oncology Light SystemAccording to the US National Cancer Institute, nearly 40 percent of Americans will be diagnosed with cancer during their lives. The World Health Organization names cancer as the second leading cause of death globally, causing nearly one in six deaths. In case anyone needs reminding, cancer is a big deal.

Alongside chemotherapy and surgery to remove tumors, about 40 percent of cancer patients are treated with radiotherapy, which fires ionizing radiation into the body, killing malignant cells with X-ray photons. Roughly 17,000 clinics worldwide deliver X-ray radiotherapy treatment today.

Traditional radiotherapy can damage surrounding tissues because it ionizes the body along its entire path, leading to the potentially serious side effects associated with cancer treatment – which is even more fraught when the cancer is located near a critical organ.

Enter the proton, the positively charged particle found in the nuclei of atoms. Proton beam radiotherapy for cancer treatment, which has been in use as far back as 1954, promises more precise control of where it delivers energy to kill cancer cells.
