Radiation therapy (RT) is used to treat a wide range of cancers by delivering highly targeted radiation to cancerous cells, destroying their ability to grow and divide while leaving healthy cells intact. Generally, RT is delivered through beams emitted from a machine outside the body or through brachytherapy, which involves placing the radiation source directly inside or near the site of the cancerous cells. Cancer patients may be treated with radiation therapy in combination with other methods such as chemotherapy, surgery, or hormone therapy, to maximize the benefit to the patient.
- Postop Radiation Slows PSA Rise in High-Risk Prostate Cancer
Researchers observed that men with high-risk prostate cancer had a significantly lower risk of biochemical relapse when treated with adjuvant radiation therapy after radical prostatectomy.
- Effectiveness of Radiation for Prevention of Mastectomy in Older Breast Cancer Patients Treated with Conservative Surgery
Researchers found that the receipt of RT after conservative surgery was associated with a greater likelihood of ultimate breast preservation for most older women with early breast cancer.
- Excellent Local Control with Stereotactic Radio Therapy Boost After External Beam Radio Therapy in Patients with Nasopharyngeal Carcinoma
According to researchers, stereotactic radiotherapy boost after external beam radiotherapy provides excellent local control for locally advanced nasopharyngeal carcinoma patients.
