Dr. Mercola's website to learn more especially you guys who every drum knock you are having scans of one form or another.....and for those of us who live in Jamaica , remember we don`t sue at the drop of a hat so you can tell your doctor no!
Despite clear evidence that the radiation from x-rays is damaging to your body, our current medical system continues to promote the careless and excessive use of radiation-based diagnostic scans.
This year, one in every 10 Americans will have a CT scan (computed tomography).
The amount of money spent on medical imaging doubled between 2000 and 2006 to about $14 billion a year—and that is just Medicare alone, according to a study by the Government Accountability Office. More than 70 million CT scans per year are now performed in the US, including at least 4 million on children. This is up from just 3million in 1980.
Nearly 30,000 get Cancer EVERY Year in the US from CT Scans
According to a study in the Archives of Internal Medicine last year, CT scans alone will cause nearly 30,,000 unnecessary cancer cases (about 2 percent of cancer cases), which will lead to about 14,500 deaths.
But wait, there’s more bad news.
While 30,000 cancer cases is a large number, a New England Journal of Medicine study from 2007 estimated that overuse of diagnostic CT scans may cause up to 3 million excess cancers over the next 20 to 30 years.
For those slow on math that is 1,000X more deaths over the next 25 years.
David Brenner of Columbia University, lead author of the study, told USA Today: "About one-third of all CT scans that are done right now are medically unnecessary … Virtually anyone who presents in the emergency room with pain in the belly or a chronic headache will automatically get a CT scan. Is that justified?"
Why are so many CT scans being done, when they result in so many unnecessary deaths?
There are several reasons:
* Physicians fear being sued for malpractice if they miss something.
* Some patients pressure their physicians for scans “just to be safe,” especially after hearing advertisements touting the benefits of new hi-tech tests (without disclosure of the risks).
* Physicians are more often using scans to screen “the worried well” (such as scanning former smokers for lung cancer).
* Many doctors have purchased their own imaging equipment for their practices. This adds a financial incentive into the mix and sets the stage for overuse of the technology.
* There’s a trend toward commercially advertised full-body CT scans to “find everything wrong with you.” Consumers with extra cash lying around (in excess of $1,000 in most cases) are being encouraged to undergo a full-body scan as a preventive measure.
While high-tech imaging can be beneficial in certain cases, it must be used SPARINGLY because it exposes your body to dangerous radiation—radiation that is proven to cause cancer.
And you are being exposed to more radiation from your diagnostic test than was previously thought. Studies have recently found that radiation doses from CT scans tend to be higher than the amounts generally reported.
When the diagnostic procedure causes the disease you are trying to avoid, perhaps you should reconsider the procedure!
Becoming aware of the risks of medical scans is part of becoming a smart consumer and knowing your health care options. Research suggests that a dismal seven percent of patients are informed of the risks of CT scans.
Why X-Rays are so Damaging to Your Health
There are four primary reasons that x-rays (and other diagnostic tests that rely on ionizing radiation, such as mammograms and CTs) should be minimized:
1. They cause chromosomal mutations that are often irreparable, and the effects are cumulative.
2. They cause DNA changes that are proven to lead to cancer.
3. They cause DNA damage in your arteries, which can lead to cardiovascular disease.
4. They often result in misdiagnosis and false positives, increasing the likelihood of follow up tests—further increasing your radiation exposure.
X-rays and other types of ionizing radiation have been, for decades, a proven cause of virtually all types of mutations—especially structural chromosomal mutations. X-rays are an established cause of genomic instability, which is frequently seen in the most aggressive cancers.
X-rays act like tiny little “grenades” that are far more damaging to your DNA than the metabolic free radicals, which are routinely produced by your cell’s natural metabolism. Ionizing radiation can damage the genetic material of every internal organ or cell lying within the path of an x-ray beam. Within an organ, even a single high-speed high-energy electron, set into motion by an x-ray photon, has a chance of inducing the types of damage that defy repair.
That is why there is no safe dose of x-rays.
And when such mutations are not lethal to the cell, they persist and accumulate with each additional exposure to x-rays or other ionizing radiation.
On top of the DNA mutation effects, there is the issue of arterial damage and increased risk of blood clots.
How can radiation move you closer to a heart attack?
Radiation damages the DNA in your arteries, which in turn causes the cells lining your arteries to multiply abnormally, decreasing the size of the arterial lumen and effectively “narrowing” your arteries. This radiation-induced tissue inside your arteries is similar to scar tissue, decreasing vessel elasticity and increasing your risk for arterial blockage.
According to John Gofman, M.D., Ph.D., evidence indicates that more than 50 percent of deaths from cancer and more than 60 percent of deaths from ischemic heart disease may be x-ray-induced.
