protoniterapiasta

Protoniterapiasta, also known as proton therapy, is a type of radiation therapy used to treat cancer. Unlike traditional photon radiation therapy, which uses X-rays, proton therapy uses a beam of protons. Protons are positively charged subatomic particles that can be precisely controlled to deliver a high dose of radiation directly to the tumor while sparing surrounding healthy tissues. This targeted approach can lead to fewer side effects compared to other forms of radiation treatment.

The Bragg peak phenomenon is a key principle behind proton therapy. As protons travel through tissue, they deposit most of their energy at a specific depth, known as the Bragg peak, and then stop. This allows oncologists to precisely target the tumor's location and depth, minimizing radiation exposure to tissues beyond the tumor. This is particularly beneficial for treating tumors located near critical organs or structures, such as the brain, spinal cord, or eyes.

Proton therapy is typically delivered in a specialized facility called a proton treatment center. Patients lie on a treatment couch, and the proton beam is delivered from a large machine called a cyclotron or synchrotron. The treatment is non-invasive and painless, with each session usually lasting a few minutes. The total number of treatment sessions varies depending on the type and stage of cancer being treated. While promising for many cancers, proton therapy is not suitable for all types of tumors and is often considered for specific indications where its advantages are most pronounced.
