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. At low doses, radiation is used in x-rays to see inside your body, as with x-rays of your teeth or broken bones Head and neck cancer refers to malignancies of the oral cavity, pharynx, larynx, paranasal sinuses, nasal cavity or salivary glands. Alcohol and tobacco use account for the majority of head and neck cancers. Suspected cases require a biopsy of the lesion, typically followed by a staging CT scan of the neck and chest External beam radiation therapy comes from a machine that aims radiation at your cancer.It is a local treatment, which means it treats a specific part of your body.For example, if you have cancer in your lung, you will have radiation only to your chest, not to your whole body

XiO is a comprehensive 3-D intensity modulated radiation therapy (IMRT) treatment planning platform that combines advanced planning tools with robust dose calculation algorithms Image Guided Radiation Therapy - Image-guided radiation therapy (IGRT) is the use of imaging during radiation therapy to improve the precision and accuracy of treatment delivery. IGRT is used to treat tumors in areas of the body that move, such as the lungs. Radiation therapy machines are equipped with imaging technology to allow your doctor to image the tumor before and during treatment 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. During this type of radiation, the high-energy beams come from. External beam radiation therapy continues to be the mainstay of treatment for this lesion. Doses of 6500 to 7000 cGy are directed at the primary lesion and the upper echelon lymph nodes. If clinically positive, lower cervical nodes are included in the field.

  1. Radiotherapy has been used for ocular and periocular indications since the beginning of the 20th century. Both external beam and radioactive plaque techniques have been employed for malignant and benign disease, with varying degrees of efficacy. Cataract, dry eye and retinopathy were once common sequelae to the use of radiation
  2. Radiation therapy. Radiation therapy uses high-powered energy beams, such as X-rays or protons, to kill cancer cells. It can be given internally or externally. Immunotherapy. Immunotherapy works with your body's immune system to fight off any remaining cancer cells by stimulating your body's own defenses or supplementing them. Targeted therapy
  3. Fast neutron therapy started as early as 1930s at Lawrence Berkeley Laboratory, California, and spread worldwide by 1970s after apparently successful clinical results were reported by Hammersmith Hospital in London (Ando and Kase, 2009).Mean neutron energies used for therapy at various facilities by 1988 were between 7.5 and 25 MeV (Wambersie, 1990), and inferior depth-dose distribution.
  4. Lymph node levels of the neck. The lymph nodes in the neck have historically been divided into at least six anatomic neck lymph node levels for the purpose of head and neck cancer staging and therapy planning. Differing definitions exist across specialties 1-4. The following is a synthesis of radiologically useful boundaries for each level

Introduction: PET/CT scan has an emerging role in head and neck oncology with a few well-established indications, including: detection of unknown primary tumor site, tumor staging, radiotherapy planning, treatment response assessment and detection of recurrent disease. The purpose of this study is reporting PET/CT findings in head and neck cancer patients to emphasize its role in head and neck. Radiation therapy. Radiation therapy uses powerful beams of energy, such as X-rays, protons or neutrons, to kill cancer cells. If your parotid tumor is cancerous, radiation therapy might be recommended after surgery to kill any cancer cells that remain. Radiation therapy is sometimes used as an initial treatment when surgery isn't an option Treatment. The treatment for laryngeal cancer largely depends on the size of the cancer. The main treatments are radiotherapy, surgery and chemotherapy. Most hospitals use multidisciplinary teams (MDTs) of specialists that work together to decide the best way to proceed with your treatment. Members of your MDT will probably include a surgeon, a.

An ENT may be able to do this in the office using numbing medicine and either forceps or a fine needle. The removed cells are sent to a pathologist, who looks for cancer cells as well as for signs. Radiation therapy is usually given both to the main nasopharyngeal tumor and to nearby lymph nodes in the neck. Even if the lymph nodes are not abnormally firm or large, radiation is still used, just in case a few cancer cells have spread there. If the lymph nodes are known to have cancer cells, higher radiation doses are used American Academy of Otolaryngology-Head and Neck Surgery. previous radiotherapy for the neck was a contraindication. It has now however been demonstrated that the flap can be safely used even in the context of previous radio-therapy. If doubt exists concerning the integrity of the pedicle, it can be assessed using preoperative angiography. Preoperative investigatio

Acoustic Neuroma. Vestibular schwannoma (acoustic neuroma) is a benign tumor of the balance nerve within the bony canal between the ear and the brain, and sometimes grows quite large toward the brain. Treatment of very small tumors with good hearing often is wait and rescan in six to 12 months. If the tumor grows, treatment is pursued. Radiation therapy uses high-energy beams, such as X-rays and protons, to kill cancer cells. Radiation therapy is most often delivered from a machine outside of your body (external beam radiation), though it can also come from radioactive seeds and wires placed near your cancer (brachytherapy). Radiation therapy is often used after surgery Radiation therapy may be used in conjunction with surgery (adjuvant radiation). In this scenario, radiation targets potential microscopic disease after surgery. Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that uses computer-controlled linear accelerators to deliver precise radiation doses to a.

Coughing up more than one teaspoon of blood is considered a medical emergency. Coughing up 100 cubic centimeters (cc) of blood—only 1/3 of a cup—is called massive hemoptysis and has a mortality (death) rate of over 50 percent. 4  Don't try to drive yourself or. Treatment usually includes radiotherapy, chemotherapy and/or surgery. Determining the goals of treatment is an important first step. The primary goal is generally to cure cancer or to considerably prolong life. Improving the patient's quality of life is also an important goal. This can be achieved by support for the patient's physical.

Radiation therapy may be another option. These treatments are generally only given when surgery can't be done. Although these types of treatments can have outcomes similar to surgery as far as the chances of the cancer spreading to other parts of the body, some studies show the cancer might be more likely to come back in the same area Slideshare Downloader, Download slideshare presentations to PDF and Powerpoint.
