What is the difference between cancer treatment and radiation?

In most cases, it’s aimed at and affects only the part of the body being treated. Radiation treatment is planned to damage cancer cells, with as little harm as possible to nearby healthy cells. Some radiation treatments (systemic radiation therapy) use radioactive substances that are given in a vein or by mouth.

Can radiation therapy be used with other treatments?

Is radiation and radiation therapy the same thing?

Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. At low doses, radiation is used in x-rays to see inside your body, as with x-rays of your teeth or broken bones.

Is radiation therapy the same as radiation oncology?

Radiation therapy is a cancer treatment that uses high-energy x-ray or other particles to destroy cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist.

How is radiation different than chemotherapy?

Chemotherapy and radiation therapy are both treatments for cancer – the uncontrolled growth and spread of cells to surrounding tissues. Chemotherapy, or “chemo,” uses special drugs to shrink or kill cancer cells. Radiation therapy, or “radiation,” kills these cells with high-energy beams such as X-rays or protons.

How many types of radiation treatments are there?

There are two broad types of radiation therapy that doctors use to treat cancers: internal and external.

What are the 3 types of radiation therapy?

Three common types of internal radiation therapy include:Brachytherapy involves radioactive material that is implanted in the body. ... Intraoperative radiation therapy (IORT) is used to treat an exposed tumor during cancer surgery. ... Stereotactic radiosurgery (SRS) is not actually surgery.

Which is worse radiation or chemo?

The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

Why do oncologists push chemo?

An oncologist may recommend chemotherapy before and/or after another treatment. For example, in a patient with breast cancer, chemotherapy may be used before surgery, to try to shrink the tumor. The same patient may benefit from chemotherapy after surgery to try to destroy remaining cancer cells.

Is radiation treatment painful?

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.

Why do people get radiation to their head?

This is done to help prevent cancer from spreading to the head even before it can.

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.
