For persons with small cell lung cancer, radiation is used:

  • As a primary treatment, when combined with chemotherapy (called chemoradiation).
  • As a standalone treatment in advanced cases of the disease, or for patients who are unable to tolerate chemoradiation.
  • To attack tumors that have spread from the lungs to the brain.
  • As a palliative, to relieve cancer-related symptoms...

Radiation therapy delivers focused high-energy x-rays (photons), gamma rays, or atomic particles. It affects cells that are rapidly dividing—such as cancer cells—much more than those that are not. Most cancers, including lung tumors, are made of cells that divide more rapidly than those in normal lung tissue.

Full Answer

What you should know about radiation therapy for lung cancer?

Radiation therapy for lung cancer also can be used to relieve symptoms caused by the cancer, such as pain, bleeding or blockage of airways by the tumor. Sometimes patients with small cell lung cancer (SCLC) will get radiation to the brain. This helps to lower the chances of the lung cancer spreading to the brain, which is common in SCLC.

What should I know about radiation therapy for lung cancer?

The type of radiation therapy that you may have depends on many factors, including:

  • The type of cancer
  • The size of the tumor
  • The tumor’s location in the body
  • How close the tumor is to normal tissues that are sensitive to radiation
  • Your general health and medical history
  • Whether you will have other types of cancer treatment
  • Other factors, such as your age and other medical conditions

What is the best treatment for lung cancer?

Some of the most common treatments available today include surgery, chemotherapy, and radiation therapy. Lung cancer surgery is intended to remove a section of the lung and surrounding tissue where the cancer may have spread.

How can radiation treat my lung cancer?

Radiation therapy for lung cancer uses high-energy beams called x-rays to destroy cancer cells by damaging their DNA. It’s very effective at controlling or eliminating tumors at specific sites in the body. The treatment can be given to cure patients whose lung cancers are confined to the chest but cannot be removed surgically.

Why is radiation used for lung cancer?

Radiation can be used before lung cancer surgery to shrink the tumor or after surgery to kill any cancer cells left in the lungs. Sometimes external radiation is used as the main type of lung cancer treatment.

What is the primary purpose of radiation therapy?

Radiation therapy kills cancer cells or slows their growth by damaging their DNA. Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors.

Why is radiation an effective treatment for cancer?

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. These breaks keep cancer cells from growing and dividing and cause them to die.

People with non-small cell lung cancer can be treated with surgery, chemotherapy, radiation therapy, targeted therapy, or a combination of these treatments. People with small cell lung cancer are usually treated with radiation therapy and chemotherapy. Surgery. An operation where doctors cut out cancer tissue.

Is radiation better than 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.

What are the advantages of radiation therapy?

The main advantage of radiotherapy is that it may help to control the growth of the cancer. For a small number of people with borderline resectable cancer and locally advanced pancreatic cancer, radiotherapy may help to make surgery possible. Each treatment session will take about 30 minutes, or longer for SABR.

What are the benefits of radiation?

In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.

What are the positive effects of radiation?

For some people, radiation therapy is intended to treat cancer by eliminating tumors, but for others, it is used as palliative treatment to relieve symptoms or pain caused by the disease.

Why is HDR brachytherapy important?

High-dose rate brachytherapy (HDR): Because the lungs support breathing and are located near the heart and other essential structures, it is important for radiation treatment to be tightly focused on tumors to avoid serious side effects. That is why HDR brachytherapy may be a beneficial treatment option for lung cancer patients.

Why do we use respiratory gating?

Respiratory gating: We also use respiratory gating to accurately target tumors by adjusting for tumor motion during IMRT. Tumors, such as those near the lungs, often move as a result of breathing and other involuntary movements in the body. Respiratory gating enables us to “paint” concentrated doses of radiation onto tumors with greater accuracy.

How does radiation help cancer?

When radiation is combined with surgery, it can be given: 1 Before surgery, to shrink the size of the cancer so it can be removed by surgery and be less likely to return. 2 During surgery, so that it goes straight to the cancer without passing through the skin. Radiation therapy used this way is called intraoperative radiation. With this technique, doctors can more easily protect nearby normal tissues from radiation. 3 After surgery to kill any cancer cells that remain.
