Currently, IMRT is being used most extensively to treat cancers of the prostate, head and neck, gastrointestinal, gynaecologic malignancies, sarcomas and central nervous system. IMRT may also be beneficial for treating pediatric malignancies.
However, IMRT may not be suitable for all situations, so a radiation oncologist will determine the suitability based on the tumour position, age and comorbidity and recommend the most appropriate treatment technique.
