Proton Therapy

Proton beam therapy is an advanced type of radiation therapy aimed at destroying cancerous cells using protons. The treatment offers pinpoint precision that delivers high-energy proton beams directly to tumors, minimizing damage to surrounding healthy tissue.

Texas Center for Proton Therapy offers latest-generation proton technology and a patient-centered approach to care.

All three treatment rooms feature latest-generation pencil-beam scanning. Small proton beams, measuring only millimeters wide, are rapidly scanned across the tumor to precisely match the shape of the tumor. It allows treatment to conform to complex shaped or even moving tumors, and reduces excess radiation to healthy tissues.

Physicians also use cone beam computed tomography (cone beam CT), which uses 3-D volumetric imaging (vs. 2-D X-ray images) to provide improved visualization, better patient positioning, and more precise treatment of cancerous tumors.

Advanced diagnostic imaging, including PET/CT and a 3-Tesla MRI are used to update your treatment plan as therapy reduces the size of your tumor.

Proton therapy:

  • Is especially effective in treating cancers in sensitive areas and for children whose bodies are still growing.
  • Uses high-energy, precisely targeted proton beams to destroy cancerous cells, leading to a lower recurrence rate for many patients.
  • Reduces exposure and damage to surrounding healthy tissue and vital organs.
  • Is non-invasive and may reduce side effects.
  • Sometimes increases patients’ tolerance of chemotherapy.
  • Patients can maintain their current quality of life during and after treatment.
  • Is sometimes effective in treating areas already treated with radiation.


Patients who live outside of the Dallas-Fort Worth area may access highly specialized care from Texas Center for Proton Therapy via Texas Oncology’s Telemedicine capability. While patients would need to travel to the center to receive treatment, in some cases, initial consultations and some follow-up care can be conducted via Telemedicine – and always in close coordination with a local Texas Oncology physician.
