The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The document discusses the Bragg peak, which is when a proton beam stops at a certain point in tissue and releases all of its energy, destroying cancer cells, before disappearing. This allows the proton beam to target cancer cells precisely and minimize damage to surrounding healthy tissue, unlike X-rays which continue radiating behind the target area. By concentrating its full energy on cancer at the Bragg peak, proton therapy maximizes treatment of tumors while reducing side effects.
The document discusses two proton treatment methods - wobbling and scanning. The wobbling method uses a thin plate to expand the proton beam, making it suitable for large tumors. The scanning method divides the proton beam intensity into several hundred parts to precisely apply the beam to the tumor size and shape, minimizing radiation exposure to surrounding tissues. This allows for more accurate radiation delivery according to the tumor shape. The document concludes that the scanning method is the most precise proton treatment option and is available at the Samsung Medical Center, which is one of only two facilities in the world that offers ultra-high speed line scanning treatment.
