Radiation Therapy
What is Radiation Therapy?
Radiation therapy is one of the most common, innovative and successful forms of cancer treatments of the modern world. It can successfully treat and cure approximately 50 unique forms of cancer1, utilizing alpha, beta and gamma radiation to destroy or damage cancer cells2. This helps prevent the rapid multiplication of the destructive cells, with minimal impact upon the somatic cells surrounding the cancerous area, and treats both primary, and advanced forms of the disease. This treatment can reduce the size of the cancer, and can relieve pain, discomfort, and other symptoms. Radiation therapy can be performed independently on a patient, or in combination with surgery, chemotherapy, and other cancer

The therapeutic and diagnostic potential of X-rays were recognized rather quickly; the first diagnostic X-ray image was taken within 2 months of Roentgen’s discovery. Fascinatingly, the therapeutic potential of X-ray beams was uncovered prior to the diagnostic element5. Emil Grubbe, a Chicago medical student, noticed the peeling of his hand after exposure to the radiation, and was granted the permission from his professor to irradiate a patient suffering from locally advanced breast cancer. In doing so, Grubbe became the first Radiation Oncologist in history. Radiation therapy was originally delivered in a few successive, high-dosage treatments. However French biologist and Radiation Oncologist Claudius Regaud proposed fractioned radiotherapy, a process still widely used in treatment programs today, after it was discovered that a singular high dose of the treatment did little to control the growth of tumorous cells and had serious side effects on the patient6. Limitations of the early machinery were soon realized, as Oncologists were unable to produce radiation beams of high enough energy to penetrate deep into tissue and treat deep-seated cancers …show more content…
The linear accelerator uses microwave technology to generate and accelerate electrons through what is called a ‘wave guide’. These are a series of negatively charged magnets that lead the electron beam into a series of metal plates, splitting the electron beam into x-ray photons (refer to fig. 2). The photon beam is then shaped by a multi-leaf collimator, incorporated in the head of the machine, to match the specifications of the tumor10 (refer to fig.3).

Role of Radiation Therapy in Treatment of Illness
The field of radiation therapy lies predominantly in the identification and safe treatment of cancers and tumors. The varying methods of treatment cover a broad spectrum of cancerous and benign tumors throughout the body. Brachytherapy is able to provide large doses of radiation to an area over a smaller time period, and lesser treatments. Intensity modulated EBRT is the most commonly practiced radiotherapy treatment method, and it can be used to treat the more delicate areas of the body. The following illnesses can be treated by radiation therapy.
Brachytherapy
Radiotherapy
Gynecologic Cancer
Brain Tumors
Prostate Cancer
Breast Cancer
Head and Neck Cancer
Colorectal Cancer
Skin Cancer
Esophageal Cancer
Breast Cancer
Head and Neck Cancer
Gallbladder Cancer
Hodgkins and

    Some advances include improved drug combinations, administration of anti-nausea medications during and after chemotherapy to reduce sickness and side effects, and chemotherapy pre-surgery to shrink a tumor or chemotherapy post-surgery to prevent recurrence of tumor (Evolution of Cancer Treatment). Another commonly administered treatment for cancer is radiation therapy. Radiation therapy is the use of high-beamed, frequently external, radiation to kill cancer cells. Radiation therapy most often gets its power from X-rays, but power can also come from protons. Radiation therapy was originated in 1989 and began as radium with low-voltage diagnostic machines.…

    Radiation treatment involves the use of high-energy particles to destroy cancer cells. An external machine delivers external-beam radiation therapy within the body over a set number of treatments over a set period of time. This line of treatment is meant to target a small, localized region affected by cancer due to its damaging effects it has on both sick and healthy cells in its path. The goal of radiation therapy is to maximize tumor control and minimize treatment toxicity. With the use of medications, chemotherapy may be administered, entering the bloodstream and attacking cancer cells throughout the body.…

    Cancer has many forms of treatment, but the two that are known to most are chemotherapy and radiation therapy. Chemotherapy is the use of drugs like cytotoxic and others, where as radiation therapy is the use of x-rays or other similar forms of radiation to cure cancer. Arguments can and more than likely always arise that one form of the two treatments is more beneficial and effective than the other. Considering this, the type of treatment that may be used can differ for each type of cancer, just depending on which one is more useful for the particular illness. The two treatment may differ in a few ways but the biggest one can be the side effects of each one.…

    Results Conclusively cancer manifests itself in many forms within organisms, with different intensity levels. In the simplest of cases there is noninvasive breast cancer, where the cancer cells are essentially localized and remain there. On the other hand there is invasive breast cancer, where the cancerous cells spread (metastasize) throughout the body by using the bloodstream and lymphs. Most cancer patients are primarily treated for breast cancer with surgery by carrying out simple or modified mastectomy or modified radical mastectomy followed by adjuvant chemotherapy plus hormonal therapy depending on the case (Khan, Bahadur, Agarwal, Sehgal, & Das, 2010). Some cancer patients also receive the treatment of neo-adjuvant chemotherapy.…

    Radiation therapy uses high-energy radiation to shrink tumors and kill cancerous cells (“Radiation”). Radiation is usually given by a machine outside of the body shooting beams of radiation at the site of the cancer. The machine that produces the radiation is called a Computed Tomography Scanner. Like chemotherapy, side effects come with the use of radiation at a treatment though. Some of the side effects are; skin problems, fatigue, jaw stiffness, shortness of breath, cough, fever, burns.…

    Stage III surgery can be used to remove the section of the colon that was affected with cancer along with the nearby lymph nodes which is followed by chemotherapy, your doctor may advise radiation therapy if the surgeon thinks some cancer cells are remaining. In most cases of stage IV it is less likely to cure cancer by surgery, however if few small areas of cancer spreads in the lungs or liver and they can completely remove it along with the colon cancer the surgery can prolong your life or may even cure you. If the metastases cannot be removed by surgery due to them being too large or there are too many of them, chemotherapy may be given before any…

    Palliation can also be used. It takes out as much of the tumor and helps to relieve the symptoms of cancer, even if it does not cure the disease itself (“Advance”). The term remission refers to a period of time when the cancer is responding to its treatment. When a patient is in remission, the cancer is under control. When someone is in complete remission, all signs and symptoms disappear.…

    When we look at the curative intent of radiation, it is used to destroy tumours that have not yet metastasized throughout the body. Radiation can also be used to kill small amount of cancer that might be remaining after a patient has undergone chemotherapy or surgery. As well as reduce the risk that cancer will return. Radiation may also be used to reduce the size or a tumour or cancerous cells before undergoing surgery for optimal success of removing the cancer with ease. If the goal is to control or reduce the symptoms caused by a growing tumour, radiation is used to improve the quality of life.…
