Study shows how radiation causes breast cancer
by S. L. Baker, features writer
(NaturalNews) It's well-established that exposure to ionizing radiation can trigger mutations and other genetic damage and cause normal cells to become malignant. So it seems amazing how mainstream medicine frequently dismisses the idea that medical imaging tests from mammograms to CT scans could play much of a role in causing breast cancer. Take this example from the web site for Cornell University's Program on Breast Cancer and Environmental Risk Factors:
In answer to the question "Is ionizing radiation a cause of breast cancer?", the Cornell experts say "Yes" and note ".. female breast tissue is highly susceptible to radiation effects." But then they pooh-pooh the possible hazard from mammography x-rays saying the risk …"should not be a factor in individual decisions to undergo this procedure. The same is true for most diagnostic x-ray procedures."
If that's not confusing enough, they turn around and state: "Nonetheless, unnecessary radiation exposures should be avoided and continued vigilance is required to ensure that the benefits associated with specific procedures outweigh the future risks."
Why radiation causes breast cancer
Common sense suggests there is plenty of reason to be worried about radiation causing breast cancer. And now there's a new reason to be concerned. Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered that radiation exposure can alter cells' microenvironment (the environment surrounding cells). And that greatly raises the odds future cells will become cancerous.
The reason is that signals from a cell's microenvironment, altered by radiation exposure, can cause a cell's phenotype (made up of all its biochemical and physical characteristics) to change by regulating or de-regulating the way a cell uses its genes. The result can be a cell that not only becomes pre-cancerous but that passes this pre-malignant condition on to future cells.
"Our work shows that radiation can change the microenvironment of breast cells, and this in turn can allow the growth of abnormal cells with a long-lived phenotype that have a much greater potential to be cancerous," Paul Yaswen, a cell biologist and breast cancer research specialist with Berkeley Lab's Life Sciences Division, said in a statement to the press.
"Many in the cancer research community, especially radiobiologists, have been slow to acknowledge and incorporate in their work the idea that cells in human tissues are not independent entities, but are highly communicative with each other and with their microenvironment," he added.
For their study, Yaswen and his research teams used human mammary epithelial cells (HMECs), the cells that line breast ducts, where most breast cancers start. When placed in a culture dish, the vast majority of HMECs display a phenotype that allows them to divide between five and 20 times until they become what is known as senescent, or unable to divide. However, there are also some variants of these cells which have a phenotype that allows them to continue dividing for many weeks in culture. Known as a vHMEC phenotype, this type of breast cell arises spontaneously and is more susceptible to malignancy because it lacks a tumor-suppressing protein dubbed p16.
To find out what radiation exposure does to the cellular environment and how it could impact the future of cell behavior, the Berkeley Lab scientists grew sets of HMECs from normal breast tissue in culture dishes for about a week. Then they zapped each set with a single treatment of a low-to-moderate dose of radiation and compared the irradiated cells to sets of breast cells that had not been irradiated.
The results, just published in the on-line journal Breast Cancer Research, showed that four to six weeks after the radiation exposure, the normal breast cancer cells had stopped dividing far earlier than they would have normally -- and this premature cell senescence had accelerated the outgrowth of vHMECS.
"However, by getting normal cells to prematurely age and stop dividing, the radiation exposure created space for epigenetically altered cells that would otherwise have been filled by normal cells. In other words, the radiation promoted the growth of pre-cancerous cells by making the environment that surrounded the cells more hospitable to their continued growth," Yaswen explained in the press statement.
The researchers pointed out that the levels of radiation used in their experiments were not as much as a woman would be exposed to during a single routine mammogram but were comparable to those a woman could receive during a CT scans or radiotherapy "and could represent sources of concern."
Of course, women are often pushed to get annual mammograms, raising their overall radiation exposure through the years. And, as NaturalNews has reported, previous research has already provided compelling evidence linking mammography to breast cancer.
For example, a report published in the Journal of the American Medical Association's Archives of Internal Medicine found that the start of screening mammography programs throughout Europe has been associated with increased incidence of breast cancer (http://www.naturalnews.com/024901.html). And a Johns Hopkins study published in the Journal of the National Cancer Institute concluded radiation exposure from mammograms could trigger malignancies in women at risk for genetic breast cancer (http://www.naturalnews.com/025560_c...).

New research: Electropollution can cause diabetes (type-3)
by Mike Adams, the Health Ranger, NaturalNews Editor
(NaturalNews) Most people are familiar with type-1 diabetes and type-2 diabetes, but did you know researchers have discovered a third type of diabetes? Type-3 diabetes, as they are calling it, affects people who are extra sensitive to electrical devices that emit "dirty" electricity.
Type-3 diabetics actually experience spikes in blood sugar and an increased heart rate when exposed to electrical pollution ("electropollution") from things like computers, televisions, cordless and mobile phones, and even compact fluorescent light bulbs.
Dr. Magda Havas, a PhD from Trent University in Canada, recently published the results of a study she conducted on the relationship between electromagnetic fields and diabetes in Electromagnetic Biology and Medicine. In it, she explains how she and her team came to discover this about why electropollution is so dangerous for many people.
Blood sugar goes haywire
One of the most interesting finding in her study was that electro-sensitive people whose blood sugar decreases when they go for a walk outdoors actually experience an increase in blood sugar when walking on a treadmill.
Treadmills, you see, are electrical devices that emit electrical pollution. But interestingly, even the physical exertion of walking on the treadmill did not make up for the blood sugar spiking effect of the EMFs emitted by the treadmills. Despite the exercise, in other words, type-3 diabetics experienced significant spikes in blood sugar when walking on the treadmill.
Dirty electricity is bad for everyone, but it is especially bad for people who are type-3 diabetics. And Dr. Havas explains in her study that even having an electrical device plugged into the wall near someone who is type-3 diabetic can cause them problems.
We have to rethink environmental influences of modern living
I find this research fascinating, not only because it proves that electromagnetic waves impact blood sugar and heart rate, but because there could be thousands, if not millions, of diabetics who may be suffering from a diabetes misdiagnosis right now.
The reason I'm bringing this up is because a 54 year-old pre-diabetic man who participated in the study was found to experience serious blood sugar spikes only when he was working in an urban environment around power lines or on his computer. When he was out camping away from the city, his blood sugar was just fine.
The man tested his blood sugar every morning in different situations and his levels were always higher when electrical fields were nearby. On one of the mornings, he forgot to test himself prior to beginning work on the computer. His blood sugar levels were higher than normal, registering around 205 milligrams per deciliter (mg/dL). But after stepping away from the computer for only ten minutes, his levels dropped nearly 20 mg/dL.
The degree to which electromagnetic pollution affects the body is clearly quite astonishing, and this study illustrates that. But it makes you wonder how many people have diabetes simply because of EMF pollution (and not solely due to their diet or lack of exercise, as we have been taught).
High EMFs gave this woman diabetes
Take the case of the 80 year-old woman whose house tested high for EMF pollution. Prior to installing a system of filters around her house designed to reduce "electro-smog" levels, her blood sugar was high and she was using insulin each day in order to balance her blood sugar levels. After installing the filters (which reduced EMF pollution by roughly 98 percent), the woman's blood sugar levels dropped by 33 percent and her insulin requirements plunged a whopping 75 percent!
This idea that reducing the electropollution of your house could drastically reduce a patient's need for insulin has never even registered in conventional (mainstream) medicine. Yet it could be a crucial understanding for tens of millions of diabetics around the world.
The study mentioned here classifies the type of diabetes caused by electromagnetic pollution as type-3 diabetes. While those with type-1 or type-2 diabetes can also have type-3, the data seems to indicate that a person can also exclusively have type-3 without any overlay of the other two types. In other words, their diabetes may be solely due to electromagnetic pollution.
And since pre-diabetics can be pushed over the edge by EMF pollution, there is no telling how many people actually have type-3 rather than type-2 diabetes.
If you ask most mainstream medical "professionals", they will deny that type-3 diabetes even exists. According to most of them, the idea that electromagnetic pollution contributes to disease is some sort of whacked out conspiracy theory. But there's more to the study that you need to know...
Wireless signals interfere with the heart
For one portion of the study, Dr. Havas had patients lie down on a bed with a cordless phone placed two feet away from their heads. The phone was plugged into the wall, but for each testing session, the electricity was either on or off.
Neither the patient nor the doctor administering the test was aware of whether or not the phone was live or dead during each session. (This is what is known as a double-blind study, the type most respected in clinical trials).
At the completion of that part of the study, researchers observed that EMF-sensitive patients experienced significant increases in their heart rates during the sessions when the phone was being powered and emitting radio signals. When it was turned off, these same patients returned back to their normal heart rates almost instantaneously.
Why is this important? First of all, a double-blind study is the litmus test used in the medical profession to verify that a study is legitimate. Since nobody involved knew when the power was on or off, the results are completely unbiased and hold a lot more sway than if it had been conducted a different way.
Secondly, it illustrates that EMF pollution really does speed up the heart rates of certain people. And since a rapid pulse is one of the many symptoms of diabetes, it seems reasonable to suspect that EMF pollution could be a fundamental cause of diabetic symptoms for a significant portion of the diabetic population.
This makes you wonder about the harm caused by mammograms, CT scans and other medical scanning technologies that blast the body with electromagnetic radiation, doesn't it?
Electromagnetic radiation leads to many diseases, including cancer
Our bodies are constantly barraged by electromagnetic radiation from numerous electronic sources, and most people don't think twice about this high level of exposure (probably because many don't even realize it's there), but the truth is that all this EMF pollution is leading to widespread illness.
Most of the recent research on EMF pollution has focused on cell phones, which makes sense because people take their cell phones with them everywhere they go and when they use them, they often hold them right next to their skulls. Cell phone radiation is probably one of the most dangerous EMF polluters because the devices remain in very close contact with the body for long periods of time.
A 2008 study published in New Scientist revealed that cell phone radiation causes human cell proteins to improperly express themselves. Similar studies also found that the radiation damages living DNA, creates leakages in the blood-brain barrier, and increases estrogen and adrenaline levels, disrupting hormone balance.
According to one statistic from a 2008 study, adults who use a cell phone over the course of a decade increase their chances of developing brain cancer by 40 percent. Even worse, a Swedish study found that people who start using a cell phone before the age of 20 increase their risk of developing a brain tumor by 500 percent!
Mainstream science holds conflicting views (as usual)
Of course, many in the medical establishment simply deny that electro-smog has anything to do with health or disease. And it doesn't matter how many studies are conducted on the matter; many continue to insist that there is not enough evidence that EMFs cause any harm.
Not everyone feels this way, of course, but sadly most of today's experts seem unable (or unwilling) to put two and two together and make the connection between electromagnetic pollution and disease.
There are many contributors to disease in our environment. EMFs represent just one. But to deny that electromagnetic pollution is harmful is quite narrow minded. Dr. Havas' study provides more than enough evidence that at least some people are suffering because of the electrical devices that surround them.
Our world, of course, is full of electromagnetic devices -- and some of them may surprise you. A typical hair dryer, for example, emits an explosion of electromagnetic radiation that's usually aimed right at the skull. Typical office environments shower employees with electropollution from fluorescent lighting, and even exercise gyms can subject visitors to a dense field of electromagnetic pollution (from all the electronic exercise machines).
It all gives credence to the idea of getting into nature more often, doesn't it? If you're sensitive to electropollution, the farther away you get from the city, the better you'll feel. No wonder most people innately gravitate to such natural environments like forests, lakes and ocean beaches.
So, does all this research mean we should all get rid of our phones and computers and return to the pre-information age? You could always join an Amish community. They're remarkably healthy, and part of that may be due to their lack of electropollution.
But for mainstream people, a more practical solution is to install some EMF filters around your home.
Some solutions for electromagnetic pollution
As mentioned in the study, home EMF filters are one of the best ways to reduce or eliminate the stray electrical signals that plague your house. These filters will capture electrical "noise" from things like televisions, computers and phones, and return it back into the line or into the ground. These can be connected to the outlets where these devices are plugged in.
Keeping Wi-Fi devices like cell phones and wireless routers away from your body as much as possible is another good idea. If you have a wireless router at home, place it away from areas where people sleep or spend a lot of time. Even having it just a few feet farther away can make a big difference in a reduction of the electropollution exposure from it.
When charging your cell phone, plug it in across the room from you. Especially at night when you are sleeping, it is best to turn off as many electrical devices as possible and to keep them away from your bed when sleeping. And beware of electric blankets: They produce a very strong electromagnetic field.
Try to use the speakerphone as much as possible when talking on the phone, or use an "air-tube" device that stops the signal short before it reaches your head. Never walk around with an idle bluetooth attached to your head, because these devices deliver a steady stream of EMF radiation directly into your head. I would recommend not using one at all, but if you do use one, take it off when not in use.
It's also a good idea to keep your phone in your pocket or purse only when necessary, and to keep it away from your body at all other times. Cell phones are intermittently communicating with network towers, so the closer they are to our bodies, the more radiation we are exposed to. So if you're not going to be using it for a while, just turn it off.
Finally, it is crucial to maintain a healthy diet and get plenty of outdoor exercise. Eating lots of nutrient-rich foods, drinking plenty of clean water, and minimizing intake of toxic preservatives, food additives, and refined sugars will do wonders to build a strong and vibrant neurological system that will resist some of the impact of electromagnetic pollution.
The reason I mention outdoor exercise is because, just like in the study, certain indoor exercise equipment like treadmills can actually cause more harm than good (for certain people). So go outside and take a walk or a jog. The sunshine will boost your vitamin D levels and the fresh air will help rejuvenate your system. (Just be sure to stay away from the power lines.){SubscribeHealthRangerBlock}
