Radiation Therapy for Head and Neck Cancer
Radiation therapy is a cancer treatment that uses high-energy beams to kill cancer cells. It is a common treatment for head and neck cancer, which is cancer that starts in the mouth, throat, sinuses, or larynx.
Radiation therapy can be used alone or in combination with other treatments, such as surgery or chemotherapy. It can be used to shrink tumors before surgery, to kill any cancer cells that remain after surgery, or to relieve symptoms caused by cancer.
There are two main types of radiation therapy:
- External beam radiation therapy: This is the most common type of radiation therapy for head and neck cancer. It uses a machine outside the body to deliver the radiation beams.
- Internal radiation therapy (brachytherapy): This type of radiation therapy involves placing radioactive material inside the body, near the tumor.
The type of radiation therapy that is used will depend on the type and stage of the cancer, as well as the patient’s overall health.
