[ RadSafe ] CT vs. X-Ray for reduction of Cancer Death

[Perle, Sandy]

A reduction of any illness/disease through the use of technology does not imply that every individual in the entire population should undergo that application/procedure with the stated goal of reducing the long-term probability of said individual to detect and minimize the effects of that illness/disease from occurring. There are many preventative exams that can be conducted today for age specific, genetically prone individuals, to be tested, at an economical cost. Just considering the cost of CT scans and the economic effect if everyone was to receive this exam, would be not cost effective. Another point is the assumption that somehow this dose may be a positive outcome is simply not acceptable. Personally I still am of the opinion that exams involving either radiological or nuclear medicine should only be utilized where there is a distinct requirement for the exam to diagnose an illness or confirm the diagnosis. The notion that everyone would benefit from a higher dose of radiation in my opinion is not acceptable, nor is there evidence that there is any positive benefit. The risks are well-known and to ignore the known facts cannot be ignored.

Regards,

Sandy
