A new study in the Journal of the National Cancer Institute suggests that CT scans, commonly used in medical imaging, may increase the risk of brain tumors.

The use of computed tomography (CT) scans has increased dramatically over the last two decades. CT scans greatly improve diagnostic capabilities (which improve clinical outcomes) but they deliver higher radiation doses than other tests. Therefore, radiation protection is a concern, especially among children, who may receive higher radiation doses, are more susceptible to radiation-related malignancies than adults and have more time to show effects from the potential risk.

The most common malignancies caused by radioactivity among children and young adults are leukemia and brain tumors. Researchers therefore evaluated leukemia and brain tumor risks following exposure to radiation from CT scans in childhood.

For a nationwide group of 168,394 Dutch children who received one or more CT scans between 1979 and 2012, researchers obtained cancer incidence and vital status by record linkage. They surveyed all Dutch hospital-based radiology departments to ascertain eligibility and participation. In the Netherlands, pediatric CT scans are only performed in hospitals.

Overall cancer incidence was 1.5 times higher than expected. For all brain tumors combined, and for malignant and nonmalignant brain tumors separately, dose-response relationships were observed with radiation dose to the brain. Relative risks increased to between two and four for the highest dose category. The researchers observed no association for leukemia. Radiation doses to the bone marrow, where leukemia originates, were low.

The researchers caution that this pattern of excess cancer risk may be partly due to confounding by indication, because the incidence of brain tumors was higher in the cohort than in the general population. CT scans are sometimes used to identify conditions associated with an increased tumor risk; the reason these children had CT scans may be associated with their risk of developing cancer.

“Epidemiological studies of cancer risks from low doses of medical radiation are challenging, said the study’s principal investigator, Michael Hauptmann. “Nevertheless, our careful evaluation of the data and evidence from other studies indicate that CT-related radiation exposure increases brain tumor risk. Careful justification of pediatric CT scans and dose optimization, as done in many hospitals, are essential to minimize risks.”

CAT SCAN RISK
Every year, many patients undergo unnecessary computed tomography (CT) scans that are not indicated, exposing them to more radiation than is necessary. Four million Americans a year are exposed to what is considered a high dose of radiation because of X-rays and CT scans.Radiation from CT scans done in 2007 will cause 29,000 cancers and kill nearly 15,000 Americans according to an article published in the Archives of Internal Medicine. Americans are overexposed to radiation from diagnostic tests, especially from a specialized kind of X-ray called a computed tomography, or CT, scan. CT scans give doctors a view inside the body, often eliminating the need for exploratory surgery. But CT scans involve much higher radiation dose than conventional X-rays. A chest CT scan exposes the patient to more than 100 times the radiation dose of a chest X-ray. About 70 million CT scans were done on Americans in 2007, up from 3 million in 1980. Radiation dosage vary between different types of CT studies, from a median or midpoint of 2 millisieverts for a routine head CT scan to 31 millisieverts for a scan of the abdomen and pelvis, which often involves taking multiple images of the same organ. By comparison, the average American is exposed to about 3 millisieverts of radiation a year from ground radon or flying in an airplane — a level not considered a risk to health. Imaging equipment makers such as GE Healthcare , Siemens , Philips and Toshiba Medical Systems are working to develop low-dose CT scanners.

Three CT scans ‘kick-start’ cancer

Three CT scans 'kick-start' cancer image

CT (computed tomography) is supposed to be a safe screening technology—but researchers have discovered that the radiation from just three scans makes cells ‘cancer-ready’.

As CT radiation doesn’t damage DNA, radiologists have been told the technology is safe—but instead the scans alter healthy cells and make them ‘cancer-capable’, which means they make cancer more possible.

Radiation from just three CT scans is enough to increase the risk, say researchers from the University of Cambridge, and create mutations in cells—known as p53 mutations—that make cells more liable to become cancerous.

The researchers have examined the effects of CT scans on cells in the esophagus—which connects the throat to the stomach—of laboratory mice. A dose, equivalent to three scans, started the spread of p53 cells until they overwhelmed the healthy cells in what the researchers called the body’s ‘Game of Clones’.

But taking an antioxidant before having a scan seems to block any damage by the scans. An over-the-counter antioxidant—the researchers used N-Acetyl Cysteine (NAC)—gives healthy cells the extra boost they need to ward off the mutant cells.

Study raises questions about the safety of MRI contrast agent; authors call for FDA action

Summary:
A comprehensive review of the known and potential risks of gadolinium toxicity commonly used as contrast agent in MRI scanning has been published by experts. Previously gadolinium was thought to accumulate only in patients with impaired kidney function. New evidence now shows that all patients are at risk. The authors call for urgent retrospective and prospective studies to assess the clinical effects on patients who have been exposed to gadolinium-based contrast during MRI scans.

Rogosnitzky, who heads the Center for Drug Repurposing at Ariel University, called upon the scientific community to quickly develop treatments for gadolinium overload. “Our literature review did not reveal a single suitable drug to swiftly remove gadolinium from the body,” he said. “In one study, the authors estimated it might take up to 156 years to remove a patient’s stored gadolinium using a particular drug.” Rogosnitzky believes that a good first step is to study existing chelator drugs used for other metal toxicities in order to assess their possible utility in gadolinium accumulation.

The published article sounds the alarm about the gap in scientific knowledge about treatment for gadolinium toxicity. “With the ominous discovery that gadolinium is retained in healthy patients, there is a critical shortage of scientific information regarding how to assess gadolinium toxicity, and perhaps most importantly, how to treat it,” Rogosnitzky said.

The magnetic field produced by an MRI is about 10 thousand times greater than the earth’s.

Other MRI Risks You May Not Know About

As mentioned, MRIs are preferable to CT scans because they do not use ionizing radiation. However, it’s still wise to minimize their use as much as possible, in part because the effects of exposure to MRIs’ strong magnetic field are largely unknown.

Research has shown that there are biological effects in the human body, however, including to the retina, pineal gland, and some cells in the paranasal sinuses.4 Time-varying magnetic fields may also interfere with your nerve cell function and muscle fibers, while MRIs also produce acoustic noise that has been known to cause temporary (and, rarely, permanent) hearing loss.

Finally, due to the strong magnetic field produced, an MRI can become deadly if metal objects in the room are not properly secured or you have medical devices such as a pacemaker in your body. There is at least one report of a child being killed during an MRI due to an unsecured metal oxygen tank.5


Dangers of X rays

XRay risk, danger, caution, harm to body and brain. Since xrays are a type of radiation, people undergoing these tests are concerned that the radiation may increase their risk of cancer. It’s true that overexposure to xrays can damage or destroy living tissue.

X-rays are a form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 to 30 000 PHz (1015 hertz). X-rays are primarily used for diagnostic radiography and crystallography. X-rays are a form of ionizing radiation and as such have risks and can be dangerous.

 

 


Is Ultrasound Scanning During Pregnancy Worth the Risks

Posted by Dr. Ben Kim on Dec 20, 2004

While ultrasound scanning doesn’t pose the same dangers to human and fetal health as ionizing radiation, it is a mistake to think that ultrasound is entirely safe for a baby growing in your womb.

Ultrasound scanning works by sending sound waves into your tissues. As these sound waves bounce off of your tissues, a picture is created.

These sound waves are capable of producing the following physiological effects:

  • Increase in blood flow and temperature in local tissues
  • Production of gas bubbles that can put pressure on local tissues
  • Mechanical effects like movement of the fluid that surrounds your cells, which can also put pressure on local tissues

The conventional view on ultrasound scanning during pregnancy is that the intensity and duration of sound waves that are used for scanning are not enough to produce these physiological effects at a level that is harmful to a fetus.

I believe that this conventional view is influenced by the number of dollars that are being made by this industry.

Before you allow ultrasound scanning to be performed during pregnancy, please consider the following points:

  1. Ultrasound scanning of pregnant women has been shown to significantly increase the likelihood of miscarriage, preterm labour, and even infant mortality.
  2. Pregnant physiotherapists who provided ultrasound treatments for more than 20 hours per week were found to have an increased risk for spontaneous abortions.
  3. One of the reasons used to support ultrasound scanning for pregnant women is that it can help to diagnose a condition called placental praevia. This is a condition where the placenta is implanted in the lower part of a woman’s uterus, which can cause bleeding in the third trimester and increase her chance of being encouraged to have a caesarean section. A study of 4000 women found that of 250 women who were scanned and diagnosed with placental praevia, only 4 actually had placental praevia upon delivery. Who knows how many unnecessary caesareans have been done and how much needless anxiety women have experienced due to incorrect diagnoses of placental praevia wiith ultrasound?
  4. Using ultrasound scanning to detect serious problems before birth does not necessarily save lives or reduce illness. There is evidence to suggest that using ultrasound to attempt to detect problems while a baby is in the womb can do more harm than good.
  5. There is evidence to support that children who have been exposed to ultrasound while in their mothers’ bellies have a greater chance of suffering from dyslexia and other speech and learning problems than children who have not been exposed to ultrasound.

Ultimately, the two main reasons why I believe that it is best to avoid ultrasound scanning during pregnancy are:

  1. No matter what intensity and duration of ultrasound waves are used, there is always a possibility of these waves creating unnecessary thermal and physical pressure to a growing baby. Why take this risk?
  2. There is always a possibility of practitioner error and/or a defective machine that can result in a higher than intended dose of ultrasonic waves to your baby.

Every disease has symptoms . If an organ isn’t working properly it will have symptoms like the lungs  [coughing persistently ]  . You don’t need these harmful diagnostic tests to tell you your having lung problems .

If a man is bleeding from the penis or has pain , frequent urination , you pretty much know it’s a prostate problem .

These test’s are so overused .  X-rays for a sprained ankle , why  ? you know what you did , you can see the ankle is swollen . Why then the need for an x-ray of the ankle ?

X-rays for broken bones 97% of the time there is no logical reason . If it’s fingers , hands , foot , toes you won’t be able to move the body part .


Again , it all comes down to money 1 Tim 6 : 10 , it’s the  exact same as taking your dog to the Vet , God forbid .

I warn you don’t have these test’s done , there really is no need . The Contrasting agent in MRI’s is especially dangerous or deadly . All the others [ CT scans , x- rays , mammograms give of high doses of radiation which can increase the risk of developing certain types of cancers as study’s have and now show .

As for  [ultra – sound ] , now you know , there are serious repercussions to the fetus to take into consideration .

 Again , it all comes down to money 1 Tim 6 : 10 , it’s the  exact same as   taking  your dog to the Vet , God forbid .
