Proton therapy did its job so Ed could keep doing his.
- Ed, librarian and head and neck cancer survivor

The MD Anderson Proton Therapy Center uses innovative technology to effectively treat head and neck tumors, especially ones that are complex and located near vital organs and tissue. Patients undergoing proton therapy treatment have fewer side effects than those receiving chemotherapy or traditional radiation.

Advantages of proton therapy:

  • No irradiation of whole head
  • Reduced damage to eyes, optic nerve, spinal cord, salivary glands and other tissue and organs near the tumor
  • Fewer side effects such as dry mouth or mouth ulcers
  • Decreased chance for loss of taste
  • Decreased need for feeding tubes
  • Decreased need for gastrostomy tubes
  • Non-invasive treatment

Cancers we treat

Head and neck cancers that the Proton Therapy Center treats include:

  • Oropharynx, including the tonsils and base of tongue
  • Periorbital
  • Parotid
  • Nasopharynx
  • Paranasal sinus
  • Oral cavity
  • Larynx
  • Skin
  • Base of skull
  • Nasal cavity
  • Submandibular gland
  • Minor salivary gland

How it works

The Proton Therapy Center's multidisciplinary team of cancer experts is dedicated to helping patients fight cancer.

In order to protect vital organs and tissue during treatment of head and neck tumors, precision is key. Our cancer experts use proton therapy to deliver a higher dose of radiation with pinpoint accuracy to target the specific shape, size and location of the tumor. This targeting reduces damage to eyes, optic nerve, spinal cord, salivary glands and other tissue and organs near the tumor.

Patient stories

The Proton Therapy Center's world-renowned team of radiation oncologists, nurses, therapists, social workers and other cancer specialists is dedicated to providing you the best experience possible. We also have the world's first proton therapy facility located within a comprehensive cancer center, designed to help ensure your optimum treatment plan.

Treatment is delivered in a comfortable outpatient setting. It is non-invasive, painless and typically has no impact on your energy level, so you can get right back to doing the things you love. Treatment varies for each patient, but most are treated daily, Monday through Friday, for eight weeks. Each treatment typically takes about 15 to 30 minutes. Head and neck patients should expect to have a mask created to help them keep their head, neck and shoulders in the same position during treatment.

Though proton therapy has fewer side effects than traditional radiation, potential ones may include:

  • Mouth and gum ulcers
  • Difficulty in swallowing
  • Loss of appetite
  • Need for a feeding tube
  • Hospitalization
