2023年1月1日 · Radiation therapy, also called X-ray therapy, uses high levels of radiation to kill prostate cancer cells or keep them from growing and dividing while minimizing damage to healthy cells....

In EBRT, beams of radiation are focused on the prostate gland from a machine outside the body. This type of radiation can be used to try to cure earlier-stage cancers, to treat cancers that have grown outside the prostate, or to help relieve symptoms such as bone pain if the cancer has spread to a specific area of bone.

2022年4月19日 · Radiation therapy for newly diagnosed prostate cancer can be divided into two main types: brachytherapy and external beam radiation. Brachytherapy, also known as internal radiation, can be further subdivided into low-dose rate and high-dose rate.

Radiation therapy is an effective treatment that kills prostate cancer cells by using high energy rays or particles. The radiation can be delivered in several ways, including brachytherapy (using seeds that are implanted in the patient’s body) and external beam radiation that projects the energy through the skin.

2023年5月10日 · External beam radiation for prostate cancer kills cancer cells by destroying the genetic material that controls how cells grow and divide. Healthy cells in the beam's path also are affected by the radiation, resulting in side effects.

What is radiation therapy? Radiation is the strategic use of ionizing radiation or photons to kill cancer cells. Radiation therapy, like surgery, is very effective at killing localized or locally advanced prostate cancer and has the same cure rate as surgery.

Radiation therapy for early-stage, localized prostate cancer includes: Low dose rate (LDR) or high dose rate (HDR) brachytherapy. Intensity-modulated radiation therapy (IMRT). Hypofractionated radiation therapy (MSK Precise®). Your radiation treatments will depend on the type of prostate cancer you have. Your radiation oncologist can help you ...

2023年12月22日 · Whether a prostate cancer patient receives external or internal radiation therapy generally depends on several factors, including the type, size, and location of the tumor. This guide covers the most common radiation treatments for prostate cancer to help patients understand what to expect.

Radiation therapy is an effective treatment for prostate cancer. Comparisons of treatment outcomes from the two most commonly used treatment options for prostate cancer, radical prostatectomy (RP) (see Your Health Matters: Radical Prostatectomy – A Patient Guide) and radiation therapy have

Radiation therapy uses high-energy particles to kill cancer cells. This procedure may cure some people with early-stage prostate cancer. It may also relieve symptoms for people with advanced prostate cancer. 1,2. Different types of radiation therapy have different risks and benefits. Talk to your doctor about the right treatment for you.
