Overview Of Radiotherapy In Cancer

  • 1. What is Radiotherapy in Cancer?
  • Radiation therapy or Radiotherapy is often abbreviated as RT, RTx, or XRT. Radiotherapy uses ionising radiation, generally as part of Cancer Treatment to control or kill malignant cells. Radiotherapy is usually delivered by a device called linear accelerator (linac). Every day, everywhe...
  • 2. Professionals Involved in Radiation Therapy Treatment Include
  • Radiation oncologists: Radiation Oncologists supervises the treatment of each cancer patient undergoing radiation treatment. They establish and administer each cancer patient’s treatment plan, make sure that every medication is correctly administered, and they track the patient’s progress and ...
  • 3. How is Radiation Therapy Used in Cancer Treatment?
  • A radiation oncologist may use either external beam radiation therapy, or brachytherapy to treat cancer. External beam Radiation therapy can be provided by a linear accelerator. Proton therapy is another type of external beam Radiation therapy that uses cyclotrons or synchrotrons to create char...
  • 4. Radiation Therapy Process
  • Once Radiotherapy has been ordered, a planning stage initiates. The patient will first undergo a simulation scan on a special CT scanner. IV or oral contrast can be used. In case a device is needed to keep the patient still (such as a mask), this is made at the simulation scan appointment. T...
  • 5. Radiation Therapy Techniques
  • Radiation can damage healthy cells. The radiation must be targeted to the cancer. An advanced type of three-dimensional (3-D) conformal radiation, called strength modulated radiation therapy, or IMRT, more specifically conforms the dose to the tumours, allowing safer delivery of higher doses of ...
  • 6. Why is Radiotherapy Needed?
  • Radiotherapy is beneficial in the treatment of cancer. About 50 per cent of patients undergo Radiotherapy at some stage during the treatment of their cancer. Radiation is a localised procedure to the cancer site destroying the cancer cells, which helps healthy cells restore themselves usually. R...
  • 7. When is Radiotherapy Required?
  • Radiation therapy, or radiotherapy, is the use of different types of radiation to safely and efficiently cure cancer and other diseases. Radiation oncologists can use radiation to cure cancer, to control the growth of the cancer or to alleviate symptoms, such as Pain. Radiation therapy works by ...
  • 8. Who Needs Radiotherapy?
  • You may have radiation after Surgery to kill cancer cells that might have been left behind. It is also prescribed as the only treatment for disabled people or others who have health problems that make it unsafe for them to undergo Surgery. Radiation also can be used instead of Surgery if th...
  • 9. How is Radiotherapy Done?
  • Radiation therapy usually takes treatment sessions five days a week for 1 to 10 weeks. The overall number of procedures depends on the size and type of cancer. Each Radiotherapy session usually takes about 10 to 30 minutes. Often, the patient is given each weekend off from therapy, which helps wi...
  • 10. Side Effects of Radiotherapy
  • Side effects are complications that may arise as a result of treatment. These can occur with Radiation therapy because the high doses of radiation that are used to destroy cancer cells may also damage healthy cells in the treatment area. Side effects are different for each individual. Many may ha...
  • 11. Before, During and After Radiotherapy
  • Before Radiation Treatment Meeting with a Radiation Oncologist for a Consult: Before determining whether you would like to undergo Radiation therapy treatments, you will first consult with a radiation oncologist to help determine whether Radiation therapy is right for you. During your app...
