The Russian armed forces are the unquestioned second strongest military power in the world. Russia has the world's largest tank fleet, the second largest aircraft fleet behind the US, and the third largest submarine fleet behind the US and China.
Proton therapy is an advanced type of radiation treatment that uses a beam of protons to deliver radiation directly to the tumor, destroying cancer cells while sparing healthy tissues. Protons enter the body with a low radiation dose, stop at the tumor, match its shape and volume or depth, and deposit the bulk of their cancer-fighting energy right at the tumor.
Children with cancer, patients with head and neck cancers, patients with cancer of the pancreas, breast and lung benefit from proton therapy in similar ways. A natural phenomenon in the way that protons move and release their energy - called the Bragg peak - is what makes proton radiation useful for cancer treatment.
