Cancer is the second cause of death in the Region, and its incidence is expected to increase considerably in the developing countries.  It has been noted internationally that Radiation therapy will continue to be key in cancer treatment in the next decades. Its curative function is particularly important in several pathologies such as cervical and uterine cancers, head and neck, and breast or prostate, without forgetting its palliative function and cost effectiveness in all the pathologies.

The effectiveness and safety of the treatments depend on many factors including the correct diagnosis and stage, the adequate therapeutic decision, the precise localization of the tumor, or planning and delivery of the treatment. This motivates the need for implementing comprehensive quality assurance programs in order to improve the effectiveness of the treatments and radiation safety for the patients.
