Have you had a CT scan lately? They are commonplace in medicine today. These sophisticated X-Rays have been beneficial in diagnosing illnesses. Are the benefits worth the risk? 29,000 people will likely get cancer as a result of the CT scans they had in 2007 according to a study by the National Cancer Institute and other research.www.npr.org/templates/story/story.php Dr Rita F. Redberg publishing the research has called it a "Public Health time bomb". The FDA is investigating the dosages in hospitals in California and in Huntsville, Alabama.
The Archives of Internal Medicine in the Dec. 14th edition reports that routine “CT scans are exposing patients to far more radiation than previously thought and … could cause tens of thousands of cancers a year….”
The symptoms of over exposure depends on how much radiation you have absorbed. The exposure level depends on the distance between you and the source of the radiation and the strength of the radiated energy. The initial signs may be nausea and vomiting, and how quickly you show symptoms from the time of the exposure is a fairly reliable indicator of the overexposure.health.msn.com/health-topics/cancer/articlepage.aspx
A proper exposure from a necessary CT scan should be a low dose and cause no problems. The doctor and technician should be aware of the exposure. There has been some concern that the CT scanners in the particular hospitals under investigation in CA and AL may be defective.
Talk to your doctor – but do not refuse a scan if it is needed. It is all about risk vs. benefits, but don’t be afraid to ask questions.
