This is done to help prevent cancer from spreading to the head even before it can. Sometimes, radiation to prevent future cancer can be given at the same time that radiation is given to treat existing cancer, especially if the area the cancer might spread to is close to the tumor itself. Sometimes cancer has spread too much to be cured.
Why is radiation the preferred treatment for cancer?
Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells.

How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.

Can radiation be used as a therapy?
Radiation can be used as a therapy too (radiotherapy). If the tumour location is known, then a very strong, focussed beam of radiation can be delivered to that specific area of the body. This then damages the DNA so much that the cell dies. 0. Dustin Welbourne.
Why is radiation a problem?
Radiation is a problem because it damages DNA. If DNA is damaged then the cell can’t respond to the cytokine, it becomes a rouge cell that doesn’t do what the body tells it to. It gets very complicated here but once a cell stops following instructions from the body it can start to misbehave very badly and we call a cell ...
Does radiation damage DNA?
The radiation here is much more powerful but much more targeted onto the cancerous cells only (where possible). As you can see, in both cases radiation causes DNA damage to change cells.

Radiopharmaceuticals are drugs that contain radioactive materials called radioisotopes.They may be put into a vein, taken by mouth, or placed in a body cavity. Depending onthe drug and how it’s given, these materials travel to various parts of the body to treatcancer or relieve its symptoms. They put out radiation, mostly in the form of alpha andbeta particles that target the affected areas. They’re most often used in small amountsfor imaging tests, but larger doses can be used to deliver radiation.
