Report Links Increased Cancer Risk to CT Scans

Well this is not a surprise. I have seen this with my own eyes. The doctors and hospitals will push getting a "CT Scan" on people and if you choose not to, you feel you are taking a big risk by not knowing something important. I myself have never had one but I have gotten WAY too many chest x-rays. Apparently, CT Scans are even more dangerous than regular x-rays.

Millions of Americans, especially children, are needlessly getting dangerous radiation from “super X-rays” that raise the risk of cancer and are increasingly used to diagnose medical problems, a new report warns. In a few decades, as many as 2 percent of cancers in the United States may be due to radiation from CT scans given now, according to the report.

The risk from a single CT, or computed tomography, scan to an individual is small. But “we are very concerned about the built-up public health risk over a long period of time,” said Eric J. Hall, who wrote the report with David J. Brenner, a fellow Columbia University medical physicist.

It was published in The New England Journal of Medicine today, and the study was paid for by federal grants. Some experts say that estimate is overly alarming. But they agree with the need to curb these tests particularly in children, who are more susceptible to radiation and more likely to develop cancer from it.

Here is some information on what a CT Scan is from the people who promote the use of CT Scans because ultimately, it benefits the bottom line of the people at the top of their organizations. This is from a medical site that is part of the medical "complex". Oh here it is - emedicinehealth is owned by WebMD and here is the background on WebMd:

Another theme Baron likes is healthcare. One name he favors is Emdeon Corp., the New Jersey-based company that owns WebMD. That medical website provides a service for corporate employees, answering their health questions as they take over more responsibility for their own medical care from employers burdened by skyrocketing insurance costs. Emdeon is also well poised to capture pharmaceutical dollars as more drug companies start to advertise online, Baron predicts. Emdeon was one of Baron Growth's biggest purchases in the first quarter of 2007.

Here is their pro-CT Scan blurb:

CT has revolutionized medicine because it allows doctors to see diseases that, in the past, could often only be found at surgery or at autopsy. CT is noninvasive, safe, and well-tolerated. It provides a highly detailed look at many different parts of the body.

If you are looking at a standard x-ray image or radiograph (such as a chest x-ray), it appears as if you are looking through the body. CT and MRI are similar to each other, but provide a different view of the body than an x-ray does. CT and MRI produce cross-sectional images that appear to open the body up, allowing the doctor to look at it from the inside. MRI uses a magnetic field and radio waves to produce images, while CT uses x-rays to produce images. Plain x-rays are an inexpensive, quick exam and are accurate at diagnosing things such as pneumonia, arthritis, and fractures. CT and MRI better evaluate soft tissues such as the brain, liver, and abdominal organs, as well as look for subtle abnormalities that may not be apparent on regular x-rays.

But then, I find this info:

New research indicates whole body medical imaging scans (like CT scans) offer little in the way of long-term health benefits and may actually jeopardize patient care. The study indicated that whole-body scans added only about six days of life expectancy for the average 50-year-old male patient. The scans also have a high risk of false-positive findings, offering “absolutely no benefit to the patient,” said researcher Dr. G. Scott Gazelle of Harvard Medical School.
