Proton Therapy Treatment

Treatment With Precision.

Proton Therapy Treatment

Proton therapy treatment is typically delivered in an outpatient setting. The treatment itself is painless and studies show that proton therapy treatment can lead to positive health outcomes for patients such as fewer short-term side effects, reduced risk of secondary malignant tumors, and faster recovery.1, 2

Prior to beginning proton therapy treatment, patients undergo either a computed tomography (CT) or magnetic resonance imaging scan (MRI).  This enables the treatment team to map the size and shape of the tumor and to create a treatment plan.

Before each treatment session, the patient receives either an x-ray or a CT to ensure that the patient is in the correct position for highly-targeted dose delivery.

During most types of proton treatments, patients lay on a treatment table and a gantry delivers the proton beam at the angle specified in the treatment plan.

The number of treatment sessions a patient receives, and the length of each treatment session depends upon the type and stage of cancer or benign neoplasm.

Advantages of Proton Therapy Treatment

Proton therapy is an advanced form of radiation treatment that uses protons to treat cancer.  Proton therapy has been shown to be effective in treating tumors near or in vital organs, including the brain, head and neck, spinal cord, breast, and lung. 

The precise delivery of protons issues less radiation to normal tissues around these sensitive sites, including the elimination of an exit dose, while increasing the treatment dose to the targeted site.3

Proton therapy is also indicated for the treatment of pediatric tumors since it can reduce the risk of harmful side-effects, such as developmental delays and decreased bone and soft tissue growth, while improving long-term health outcomes by reducing the chance of secondary cancers later in life.4

The advantages of proton therapy treatment include: 5, 6

  • Ability to target tumors with precision allowing treatment in close proximity to critical structures
  • No exit dose, therefore, minimizing radiation exposure to healthy tissues and organs
  • Ability to target tumors with high dose
  • Fewer short-term side effects
  • Reduces the risk of long-term side effects, including the development of secondary malignant tumors
  • Faster recovery
