- Neutron Beam Therapy. Like proton therapy, neutron beam therapy is a specialized form of radiation therapy that can be used to treat certain tumors that are radioresistant, meaning that they are very difficult to kill using conventional radiation therapy. Neutron therapy can also be used to treat certain inoperable tumors. Stereotactic Radiotherapy Stereotactic radiotherapy is a technique that allows your radiation oncologist to precisely focus beams of radiation to destroy certain types of tumors.

Overview Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often gets its power from X-rays, but the power can also come from protons or other types of energy. The term radiation therapy most often refers to external beam radiation therapy. During this type of radiation, the high-energy beams come from a machine outside of your body that aims the beams at a precise point on your body. During a different type of radiation treatment called brachytherapy (brak-e-THER-uh-pee), radiation is placed inside your body.

Proton Therapy Proton therapy, also called proton beam therapy, is a type of radiation treatment that uses protons rather than x-rays to treat cancer. A proton is a positively charged particle.At high energy, protons can destroy cancer cells.Doctors may use proton therapy alone, or they may combine it with standard radiation therapy, surgery, chemotherapy, and/or immunotherapy. Like standard x-ray radiation therapy, proton therapy is a type of external-beam radiation therapy.It painlessly delivers radiation through the skin from a machine outside the body.octors may use proton therapy alone, or they may combine it with standard radiation therapy, surgery, chemotherapy, and/or immunotherapy. Like standard x-ray radiation therapy, proton therapy is a type of external-beam radiation therapy.

- In radiation therapy (also called radiotherapy), invisible high-energy rays or beams of subatomic particles are used to damage cancer cells and can stop them from growing and dividing. This ultimately can kill the cancer cells treated with radiation. A specialist in radiation therapy is called a radiation oncologist.xternal radiation therapy is usually given on an outpatient basis in a hospital or clinic with specialized equipment 5 days a week for a number of weeks. Patients are not radioactive during or after the treatment with external beam radiation therapy.

Radiation Therapy Radiation Therapy. Radiation therapy, or radiotherapy, is the medical use of radioactive particles to kill and/or control the growth of malignant (cancerous) cells. In this treatment, high-energy subatomic particles are used to remove electrons from their atomic and/or molecular structure: a process known as ionization.istory of Radiation in Cancer Treatment. Radiation was being used to treat cancer more than 100 years ago. The discovery of x-rays in 1895 marked the beginning of its medical use.
