What type of radiation is used in brachytherapy?
Brachytherapy is a form of radiation therapy where a sealed radioactive source is placed, inside, on or near the tumour. Brachy comes from the Greek word for short.

What are the different types of radiation therapy?
Three common types of internal radiation therapy include: 1 Brachytherapy involves radioactive material that is implanted in the body. Dozens of tiny “seeds” containing radioactive iodine are placed at the tumor site with a special needle or catheter. This is done as an outpatient procedure. Brachytherapy is used for treatment of prostate, cervical, endometrial, vaginal and breast cancers. 2 Intraoperative radiation therapy (IORT) is used to treat an exposed tumor during cancer surgery. IORT delivers a high dose of radiation to a surgically exposed treatment area. Surrounding healthy organs and tissues are protected by lead shields. This type of radiation can be used for certain gastrointestinal cancers and other cancers that are challenging to remove during surgery. 3 Stereotactic radiosurgery (SRS) is not actually surgery. Instead, it uses dozens of tiny radiation beams to treat tumors in the head and neck with a single radiation dose. MD Anderson uses the Gamma Knife® SRS system. Gamma Knife is used to treat cancer that has spread to the brain or head or neck area, as well as tumors in the base of the skull, malignant gliomas, acoustic neuromas, pituitary tumors and meningiomas.
How is radiation delivered to cancer?
External beam radiation therapies are delivered through a specialized machine directly to the cancer site.

How does stereotactic radiation work?
Stereotactic radiation therapy involves focusing the radiation beam on a small area and delivering very high doses. The therapy targets a tumor from many different directions so the beams of radiation converge on the tumor. This way, the ideal amount of radiation needed to destroy tumor cells is delivered directly to the tumor growth, ...
What is external beam radiation?
External beam radiation therapy is radiation delivered from a distant source, from outside the body and directed at the patient's cancer site. Systems which produce different types of radiation for external beam therapy include orthovoltage x-ray machines, Cobalt-60 machines, linear accelerators, proton beam machines, and neutron beam machines. A radiation oncologist makes decisions regarding the type of system that is best suited to treat a specific cancer patient. External beam therapy is the radiation therapy treatment option used for most cancer patients. It is used to treat many types of tumors including cancers of the head and neck area, breast, lung, colon, and prostate.

It depends on the amount of radiation that wasused before.In other instances, radiation might be used in the same area of the body or
How does cancer spread?
Cancer can spread from where it started to other body parts. Doctors often assume thata few cancer cells might already have spread even when they can’t be seen on imagingscans like CT scans or MRIs. In some cases, the area where the cancer most oftenspreads to may be treated with radiation to kill any cancer cells before they grow intotumors. For instance, people with certain kinds of lung cancer may get radiation to thehead, even when there is no cancer known to be there, because their type of lungcancer often spreads to the brain. This is done to help prevent cancer from spreading tothe head even before it can. Sometimes, radiation to prevent future cancer can be givenat the same time that radiation is given to treat existing cancer, especially if the area thecancer might spread to is close to the tumor itself.
Can cancer be cured?
