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:
- They cause
chromosomal mutations that are often irreparable, and the effects
- They cause
DNA changes that are proven to lead to cancer.
- They cause
DNA damage in your arteries, which can lead to cardiovascular
- They often
result in misdiagnosis and false positives, increasing the likelihood
of follow up tests – further increasing your radiation exposure.
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.

chance of inducing the types of damage that defy repair.

And when such
mutations are not lethal to the cell, they persist and accumulate

On top of the

There is no
good estimate of the frequency of these radiation accidents –
regulators and researchers can only guess how often radiologic mishaps
occur. They're chronically underreported, and some states don't
require they be reported at all.
Dr. John Feldmeier,
an authority on the treatment of radiation injuries, estimates that
1 in 20 patients will suffer radiation injuries. According to the
New York Times article, the nation's largest wound care

CT scans emit

conventional chest X-ray, and a mammogram
delivers 1,000 times more radiation.

of Children Die Every Year from CT Scans
of radiation are of particular danger to children, because they
have many developing cells and organs. Children also have many years
of life ahead of them over which they will experience multiple x-rays
– and the risk is cumulative.
What is inexcusable
is that CT scans given to kids are typically calibrated for
adults. Children are routinely receiving two to six times the
radiation necessary to accomplish the task (American
Journal of Roentgenology 2001).
As a result,
it is estimated that 1500
children may die each year from CT scans they had earlier in life.
How You Can
Protect Yourself from u201CIndecent Exposureu201D
I would encourage
you to avoid x-rays whenever possible.
There may be
times when a CT scan is warranted, depending on your condition.
But oftentimes a CT scan can be substituted with an MRI or an ultrasound,
both of which have fewer harmful side effects, while still able
to produce the necessary information.
Berkeley Wellness Letter offers some good suggestions for questions
you should ask before undergoing a diagnostic scan:
- Is the test
- What difference
will it make in my care?
- Is there
a non-radiation alternative, such as ultrasound or MRI?
- Is the facility
accredited by the American College of Radiology?
- Will the
test use the lowest level of radiation for adequate imaging? (Will
it be adjusted for my size, or my child's size?)
- Will the
scan be limited to the indicated area, and will nearby areas be
Avoid CT Scans
Unless Your Life Depends on It
I believe the
evidence is very clear that you need to avoid CT scans at all costs.
There is absolutely no justification to use a full body scan as
a screening of any sort. That is just utter nonsense and the risk
in no way justifies the benefit.
CT scans are useful diagnostically, but in most cases MRIs can provide
similar imaging results and at this time appear to be far safer.
to Help You Strengthen Your Body Against the Assaults of Medical
to seeking to avoid unnecessary radiation exposure and using the
safest medical testing available whenever you do need a medical
image test, you may be able to lower your radiation-induced risk
for cancer by using a potent antioxidant.
If, for whatever
reason you are forced into a CT scan, this is the best advice I
can give you, to protect yourself from this massive ionizing radiation
is a potent carotenoid and everything I have studied suggests it
is the most potent antioxidant to protect against this type of damage.
You can take 2–4 mg of astaxanthin to protect your cells and
however, is that you need to be on it for several weeks
to prevent the damage.
The side benefit
is that the astaxanthin will also likely prevent the most common
cause of blindness, age related macular degeneration, cataracts
and also help protect you from getting sunburned.
A 100% Safe
Imaging Alternative to Mammograms
earlier, mammography is another example of overused, risky imaging
technology. Not only does it expose you to potentially dangerous
amounts of radiation, it also compresses your breasts tightly, which
can actually spread dangerous cancer cells, should they exist.
guidelines now call for women under 50 to forego routine screening
mammography. This is a small step in the right direction; however,
there is a far better option.
I highly recommend
particularly for breast screening.
screening is entirely safe, non-invasive, and brilliantly simple.
This technology measures the radiation of infrared heat from your
body and translates the information into anatomical images.
There is no
pressure or compression of your breasts, and no radiation. Perhaps
best of all, this imaging system can detect signs of breast cancer
up to 10 years before either a mammogram or a physical exam.
If your doctor
or other health care provider recommends a CT scan, mammogram or
other imaging technique as either a screening tool or to diagnose
a physical complaint, I strongly encourage you to explore all your
options before agreeing to be radiated.
