IMRT or Intensity-modulated radiation therapy is used to treat cancerous and noncancerous tumours. Radiation beams fit the shape of the tumour and target it in order to limit side effects and damage to healthy tissue.
However, spreading out low doses of radiation may cause acute or late radiation side effects, depending on which organs are within this low dose region. Another source of toxicity from IMRT relates to the unevenness of the dose.
IMRT is given five days a week for four to eight weeks. The total dose of radiation and the number of treatments you need will depend on the size of your cancer, general health, and other medical treatments you may need.
Some studies have shown that patients receiving IMRT treatment can achieve an overall survival of more than 80%. IMRT costs around USD 916 to USD 2,124.
