Radiation treatment for lung cancer requires the use of high-energy rays or particles to kill cancer cells. The Radiation treatment for lung cancer works in cancer cells by damaging their DNA and inhibits their ability to grow and divide. When cancer cells try to divide, they realize their DNA has damaged and dying instead.
They then naturally eliminated from the body. Tumors that grow quickly, like the lung cancer small cell, will find that their DNA has damaged more quickly. Therefore will die more rapidly. Tumors that grow more slowly, such as cancer of the lung non-small cell, so too will die slowly. Healthy cells also affected by radiation but can fix themselves in ways that are not cancer cells.
External beam radiation treatment for lung cancer
External beam radiation therapy is an effective method of providing high-energy rays to cancer. A machine called a linear accelerator radiation beam focusing down to the exact location in the body to the right time. This type of radiation healing used to handle primary lung cancer or metastasis to other organs. Each therapy only a several minutes, not containing setup time. Radiation treatment usually given five days a week for several weeks.
Today, traditional external beam radiation not used as regularly as in the past, and more lately the technique allows doctors to more accurately treat lung cancer while minimizing exposure to nearby healthy tissue. Most doctors recommend this method when they are available.
Three-dimensional Conformal radiation therapy combines multiple radiation treatment fields to provide radiation dose that is right for the lung tumor.
Intensity is modulated radiation therapy is a unique form of 3D-CRT that modifies the radiation intensity by varying the radiation beam respectively. This technique used if the tumors are near structures such as the spinal cord.
Stereotactic body radiation therapy is a particular form of IMRT radiation doses that provide small and high precise defined targets for treatment, often in some treatment as three to five shortened. This kind of radiation therapy used to treat lung cancer very early stage. Proton beam therapy is a type of radiation therapy that uses a beam of protons instead of x-rays.
Internal radiation treatment for lung cancer
Brachytherapy often used to shrink tumors and to relieve symptoms caused by cancer of the Lung in the airway. This procedure is usually done through the bronchoscope, although it can also do through surgery. The doctor puts a small amount of radioactive material, often in the form of pellets, either directly into cancer or to the airway in cancer. Because the radiation is just a short drive from the source, there is an effect on the healthy tissue around it.
External beam radiation therapy used as the main treatment for lung cancer, often in combination with chemotherapy. This is especially true if the tumor can’t removed surgically because of size or location, or because of the poor health status of the patient. If the patient’s tumor can eliminate by surgery, radiotherapy can use either alone or in combination with chemotherapy after surgery to try to kill remaining microscopic illness. Radiation therapy may use to relieve the symptoms of lung cancer.
Treating radiation treatment for lung cancer For non-small cell
Non-small cell lung cancer treated with surgery, but mainly patients who are not surgical candidates addressed with stereotactic body radiation therapy. An excellent alternative is non-invasive and completed within one to five treatments.
Tumors that stretch outside of the lung itself or where there is a direct involvement of lymph nodes treated with surgery, followed by chemotherapy. Conventional external beam radiation therapy recommended for patients whose health status that exempts them from an operation.
Tumors that spread to other organs or involves the lymph nodes in the mediastinum can treat with some different ways. For some patients, chemotherapy alone or chemotherapy and radiation therapy combined (chemoradiation) followed by surgery are reasonable. For others, chemoradiation therapy without surgery options. Radiation administered for a few weeks.
Tumors have spread from the lungs and involve other locations in the body such as the brain, bone or liver. Although they treated with chemotherapy, radiation therapy used to control the tumor locally to prevent symptoms such as pain. Treatment usually lasts one to two weeks.
For lung cancer small cell:
Lung cancer small cell Limited Stage is limited to the chest. Approximately by stage I-III for non-small cell lung cancer. Treated mainly with concurrent chemotherapy and radiation. Because there is a high level of microscopic tumor deposits in the brain. Prophylactic Cranial Irradiation gave after the patient has completed chemoradiation to the chest.
Extensive stage small cell lung cancer is metastatic disease and by stage IV non-small cell lung cancer. Treated primarily with chemotherapy, with the radiation therapy that used to control local tumors to prevent symptoms. Treatment usually lasts one to two weeks.
