radiation may be used as a treatment for lung cancer to achieve which treatment goals?

by Mr. Daron Altenwerth III Published 2 years ago Updated 2 years ago

For lung cancer, radiation therapy may be given in combination with other treatments, including chemotherapy. It may be used to shrink tumors before surgery or to kill remaining cancer cells after surgery. Radiation therapy may also be used instead of surgery for early-stage disease or for patients who aren’t healthy enough to have surgery.

Full Answer

How does radiotherapy treat lung cancer?

Radiation oncologist Andreas Rimner delivers radiation to lung cancer patients using a GPS-type approach that tracks the tumor’s precise location at all times. Radiation therapy uses high-energy beams called x-rays to destroy cancer cells by damaging their DNA.

What type of radiation is used to treat cancer?

Radiation therapy Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often uses X-rays, but protons or other types of energy also can be used. The term "radiation therapy" most often refers to external beam radiation therapy.

What is radiation therapy for non-small cell lung cancer (NSCLC)?

Radiation therapy uses high-energy rays or particles to kill cancer cells. Depending on the stage of the non-small cell lung cancer (NSCLC) and other factors, radiation therapy might be used: As the main treatment (sometimes along with chemotherapy ), especially if the lung tumor can’t be removed because of its size or location, ...

What is the best treatment for small cell lung cancer?

Radiation Therapy for Small Cell Lung Cancer. At MSK, the approach your doctors recommend will depend on the stage of your disease. People with limited-stage small cell lung cancer confined to the chest simultaneously receive a combination of chemotherapy and radiation therapy to shrink the tumor.

What are the 2 goals 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.

What are the primary goals of radiation therapy treatment?

While both healthy and cancerous cells are damaged by radiation therapy, the goal of radiation therapy is to destroy as few normal, healthy cells as possible. Normal cells can often repair much of the damage caused by radiation.

What does radiation therapy do for lung cancer?

Lung cancer radiation therapy uses powerful, high-energy X-rays to kill cancer cells or keep them from growing. Radiation may come from outside the body (external) or from radioactive materials placed directly inside the lung cancer tumor (internal/implant). External radiation is used most often.

What is the best radiation treatment for lung cancer?

External beam radiation therapy (EBRT) focuses radiation from outside the body onto the cancer. This is the type of radiation therapy most often used to treat NSCLC or its spread to other organs. Treatment is much like getting an x-ray, but the radiation dose is stronger.

What is radiation used for?

Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity. In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.

How is radiation treatment?

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.

How well does radiation work on lung cancer?

Radiation therapy for lung cancer can be very effective for destroying cancerous cells and shrinking tumors. However, like many other treatments, it can cause certain side effects.

Stereotactic body radiation therapy (SBRT): Preserving healthy tissue is important for many lung cancer patients, who may be struggling with other conditions like emphysema. With stereotactic body radiation, the procedure: Delivers higher radiation doses to tumors, which would not be possible with other radiation therapies.

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.

Radiation exposure to healthy lung tissue and nearby organs is limited or eliminated, reducing side effects like difficulty breathing. Intensity modulated radiation therapy (IMRT): Three-dimensional planning with IMRT allows the radiation oncologist to simultaneously treat lung cancer tumors with different doses of radiation, ...

What is EBRT treatment?

External beam radiation therapy (EBRT): EBRT helps to lower the risk of side effects typically associated with radiation treatment for lung cancer, such as difficulty breathing or heart damage. Some additional advantages of EBRT may include:

Can a lung tumor be damaged by radiation?

As a result, the tumor may not receive enough radiation, and healthy tissue near the tumor may be damaged. The CyberKnife software and respiratory tracking system allows us to confirm the location of the lung tumor and continually track its movement, in real time, helping us more precisely deliver radiation without damaging healthy surrounding ...

How long does radiation treatment last in the lungs?

Most often, radiation treatments to the lungs are given 5 days a week for 5 to 7 weeks, but this can vary based on the type of EBRT and the reason it’s being given. Newer EBRT techniques have been shown to help doctors treat lung cancers more accurately while lowering the radiation exposure to nearby healthy tissues.

What is the treatment for non-small cell lung cancer?

Radiation Therapy for Non-Small Cell Lung Cancer. Radiation therapy uses high-energy rays or particles to kill cancer cells. Depending on the stage of the non-small cell lung cancer (NSCLC) and other factors, radiation therapy might be used: As the main treatment (sometimes along with chemotherapy ), especially if the lung tumor can’t be removed ...

Radiation therapy for lung cancer uses high-energy beams called x-rays to destroy cancer cells by damaging their DNA.

What is a lung cancer IMRT?

Some people with lung cancer may be treated with a specialized form of IMRT called image-guided radiation therapy (IGRT). IGRT involves the use of sophisticated imaging tests to verify the position of the patient and the location of the tumor prior to and during the delivery of the treatment.

What is proton therapy?

For some cases of lung cancer, our radiation oncologists can use proton therapy, an advanced form of radiation therapy, to deliver high doses of radiation to tumors that may be resistant to conventional forms while minimizing exposure to the surrounding healthy tissues. Proton therapy directs its cancer-fighting energy to precise locations within ...

If you have advanced non-small cell lung cancer that is confined to the chest and have your tumor surgically removed, you may be treated with a five-to-six-week course of radiation therapy before or after your surgery depending on your specific situation.

How does proton therapy work?

Proton therapy directs its cancer-fighting energy to precise locations within the body, allowing our doctors to deliver the necessary dose to the tumor — maximizing the chance of destroying it — while simultaneously lowering the dose to normal tissues and thereby reducing the risk of treatment-related side effects .
