Patients are not doctors and they faithfully go by whatever medical advice they receieve from. Doctors hardly bother to advise their patients that over radiation is a great hazard and its repetition may lead to even cancer. Physicians are competent persons or say they are supposed to behave as such but they don't, they rather are the ones contributing to number of xrays being increased which they do under the garb of going by a trustworthy one which statement is not correct as this they do for their commercial reasons by doing it themselves. As per survey made by International Atomic Energy Agency, more the number of x-rays, more the chances of the patients developing cancer. This can better be remedied when patients themselves are cautious enough to see that x-rays are there only need based and not as a matter of spree with repetitions.
