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 radiation therapy cause cancer?
Radiation Therapy: The Basics. Cancer is caused by cells growing out of control. As the number of cells grow, they form into a mass or tumor. Cancer cells, which make up the tumor, grow and reproduce very quickly. Normal, healthy cells know to stop reproducing and growing when they touch other cells. Cancer cells do not and keep on growing.
Why is radiation called localized treatment?

Types of Radiation Therapy
To understand success rates when treating lung cancer with radiation therapy, it's important to look at the different methods/types of radiation and the goals of treatment. Radiation therapy has changed considerably in recent years and has become much more effective and precise (fewer side effects) than in the past.
Small Cell Lung Cancer (SCLC) Success Rate
Small cell lung cancer accounts for roughly 13% of lung cancers and tends to spread early (often to the brain) and aggressively. 10 Roughly one-third of these cancers are diagnosed when they are considered "limited stage" tumors, and two-thirds are already extensive at the time of diagnosis. 11
Non-Small Cell Lung Cancer (NSCLC) Success Rate
The effects of treatments for non-small cell lung cancer are reported in different ways. In some cases, these are divided by the four stages of the disease. In others, they are roughly broken down into three stages: local tumors (stage 1 and some stage 2 tumors), regional (some stage 2 and some stage 3 tumors), and distant (stage 4 lung cancer).
Influencing Factors
There are a number of factors that can influence the success rate of radiation therapy, and it's important to keep these in mind when looking at general statistics that compare people as a whole.
Side Effects
As with any cancer treatment, radiation therapy can have side effects and adverse reactions at times. Some of these include:
Talk to Your Healthcare Provider
There is a lot of information to digest simply looking at the role of radiation therapy in the different types and stages of lung cancer, but individual differences are crucial as well. Every person is unique, and every lung cancer is different in some way.
Summary
Radiation therapy may be used for nearly any type or stage of lung cancer, but treatment goals differ. In early-stage lung cancer, radiation may be used in an attempt to cure the cancer. In this case, specialized radiation called stereotactic body radiotherapy (SBRT) may be as effective as surgery in some settings.

Overview
Why It's Done
- More than half of all people with cancer receive radiation therapy as part of their cancer treatment. Doctors use radiation therapy to treat just about every type of cancer. Radiation therapy is also useful in treating some noncancerous (benign) tumors.
Risks
- Radiation therapy side effects depend on which part of your body is being exposed to radiation and how much radiation is used. You may experience no side effects, or you may experience several. Most side effects are temporary, can be controlled and generally disappear over time once treatment has ended. Some side effects may develop later. For example, in rare circumsta…
How You Prepare
- Before you undergo external beam radiation therapy, your health care team guides you through a planning process to ensure that radiation reaches the precise spot in your body where it's needed. Planning typically includes: 1. Radiation simulation.During simulation, your radiation therapy team works with you to find a comfortable position for you during treatment. It's imperative that you li…
What You Can Expect
- External beam radiation therapy is usually conducted using a linear accelerator — a machine that directs high-energy beams of radiation into your body. As you lie on a table, the linear accelerator moves around you to deliver radiation from several angles. The linear accelerator can be adjusted for your particular situation so that it delivers the precise dose of radiation your doctor has order…
Results
- If you're receiving radiation to a tumor, your doctor may have you undergo periodic scans after your treatment to see how your cancer has responded to radiation therapy. In some cases, your cancer may respond to treatment right away. In other cases, it may take weeks or months for your cancer to respond. Some people aren't helped by radiation therapy.
