In the present situation, there are instances wherein the radiation therapy which is used to cure the people is underutilized in various countries. This is technical because of the reason that people these days are becoming extremely careful in using this therapy as a straitjacket solution to cure the deadly disease of cancer in every age. Therefore, what matters the most is basically the fact, that people are becoming aware of the ill-effects of such therapies in the countries which have a greater degree of the elderly population.
