Radiation oncology in Derry, New Hampshire

Parkland Medical Center's radiation oncologists precisely target tumors to kill or slow the growth of cancer cells. Our specialists may suggest radiation therapy in combination with other cancer treatments to provide a comprehensive plan of care.

For more information about radiation therapy and other cancer treatment options, call our Consult-A-Nurse® team at (877) 642-2362.

To ensure the best possible outcomes of radiation therapy, we partner with highly skilled radiologists, interventional radiologists, physicians and clinical staff. Your oncologist and nurse navigators can discuss two types of radiation therapy with you: external beam or internal. Your cancer care team may also recommend both types of therapy depending on your specific diagnosis.

External beam radiation

External beam radiation uses high-energy rays (or beams) to target cancer from outside the body. This is the most common type of radiation therapy.

There’s also a special type of external beam radiation: stereotactic radiosurgery (SRS), or stereotactic body radiotherapy. This procedure uses focused beams to target well-defined tumors. SRS benefits patients by rapidly delivering concentrated radiation to tumors and minimizing damage to nearby healthy tissue.

Internal radiation

Internal radiation treatments, also known as brachytherapy, involve inserting a source of radioactive material (often called a "seed") into a body cavity. For the treatment of gynecologic or breast cancers, this sealed source is sent into the body through a catheter for a short period—usually just a few minutes.

You may also be a candidate for:

  • Accelerated partial breast irradiation, which is a five-day radiation treatment
  • High dose rate radiation treatment, which targets cancer sites using specialized equipment
  • Prostate brachytherapy, which is a one-time procedure where a cancer surgeon inserts radioactive “seeds” directly into the prostate gland

Other types of radiation therapy for cancer treatment

Through our cancer care program, we give patients access to advanced technologies for radiation therapy. These additional procedures include:

  • Ablative techniques: Our ablative techniques use high heat or extreme cold to eliminate cancer cells.
  • Embolic techniques, or selective internal radiation therapy: We can use nuclear medicine or chemotherapy to inject material directly into a tumor.
  • Minimally invasive interventional radiology: Minimally invasive interventional radiology techniques may be an excellent choice if you can't tolerate conventional surgery, chemotherapy or radiation therapy. These tumor-focused procedures can mean fewer side effects and more rapid recovery.
