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.

How does cancer spread?

Cancer can spread from where it started to other body parts. Doctors often assume that a few cancer cells might already have spread even when they can’t be seen on imaging scans like CT scans or MRIs. In some cases, the area where the cancer most often spreads to may be treated with radiation to kill any cancer cells before they grow into tumors. For instance, people with certain kinds of lung cancer may get radiation to the head, even when there is no cancer known to be there, because their type of lung cancer often spreads to the brain. 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.

What happens if a cancer cell doesn't divide?

This is a complex question.
