To kill the cancer cells in the body we use the method called “radiotherapy”. All the cells in the body which we are going to treat are being affected by the “radiotherapy”. If the cells are healthy then it takes time to cure with this principle “radiotherapy”. radiotherapy is used to cure particular part of the body which is affected by “cancer” cells.
The space being treated is called as radiotherapy field.
Certain course is being prescribed for cancer patients. this course may contain many doses, usually referred as fractions. The number of fractions required would depend on the amount of tissue that is to be treated. Radiotherapy treatment is not routinely given over the weekend.
Radiotherapy can also be given to the scar left by a biopsy, drainage tube or operation. This is to prevent the “Mesothelioma lung cancer” from spreading into the site as small microscopic deposits may have occurred during the insertion and removal of drains, biopsy needles or surgical instruments.
Radiotherapy can be used in “Mesothelioma” to reduce the size of the “tumour” to help to relieve symptoms, such as pain or discomfort.
In “Mesothelioma radiotherapy” may also be given to much larger areas. The whole chest area on the affected side of a patient can be treated following surgery, to kill diseased cells that it was not possible to remove during surgery. (Please see the Surgery section for further details about Surgery and Mesothelioma)..
“Mesothelioma” small scars are often treated with 3 doses (fractions) of radiotherapy. When treating to relieve symptoms such as pain up to 10 doses (fractions) may be necessary. When given after surgery to a large area up to 30 treatments may be required..
Radiotherapy does not make you radioactive – it is safe for you to be with other people (including children) throughout your treatment.
You can eat and drink normally before and after each radiotherapy session.
Radiotherapy treatments are totally painless (like having an ordinary x-ray).
You will be asked to remain still during treatment but you can breathe normally.
Each radiotherapy session lasts from a few seconds to several minutes.
