Using high-energy external radiation beams from linear accelerators Radiation therapy aims to destroy (or at least damage) cells so that they cannot grow or divide.
Not only do the rays used in this treatment (called external beam radiation therapy or EBRT) go deep into the cancerous areas to work on destroying the cells but they can also alleviate symptoms such as pain or trouble breathing.
After surgical procedures (essential for extrapleural pneumonectomy patients) radiotherapy is used to help reduce mesothelioma reappearance and improve survival rates
The treatment has to be delivered precisely and this is achieved by using computed tomography (CT) scan and PET scans. Because the precise areas for delivery are identified it allows for higher doses to be delivered as normal areas are not so easily affected. However doses may have to be limited depending on the size of the tumor or its proximity to vital organs.
A recent advance in radiation treatment is the Intensity-modulated radiation therapy (IMRT) which has shown noticeable progress
in reducing local recurrences by giving access to
cancerous areas that could not be reached by
traditional radiation methods.
