[NaturalNews] We’ve all heard the jokes about stress turning our hair grey, and everyone understands that stress feels uncomfortable and can cause short term health and psychological issues. However, there was never any conclusive proof that chronic stress could actually shorten your life span by accelerating the aging process until recently.
Stress actually damages your DNA
New research indicates that chronic stress like the kind we experience in high stress occupations actually erodes and damages critical parts of our DNA over time. This damage and erosion can increase our odds of living a shorter life span.
The study showed that those under chronic stress exhibited shortened telomeres. Telomeres are the protective edges that bind the ends of DNA strands together. The damage of these telomeres leads to errors in how the DNA instructs cells to behave, so their length is directly tied to our longevity.
The shortening and damage of these mechanisms leads to a heightened potential for mutations in otherwise healthy cells and genes. When our genetic code and transmission is broken, it means our bodies have a higher likelihood of cancer and other life shortening diseases and generally poor health.
The evidence shows that stress can actually shorten your life span by as much as four to eight years depending on how you handle it and your genetic predispositions and general health. Exercise and a healthy diet can help offset some of the damage done by stress, but chronic and heavy stress is a hard thing to completely overcome by lifestyle alone.
Stress makes you sick
Not only does stress facilitate damaged DNA and shorten life spans. It can also literally make you get sick a lot more often than you should. Studies have shown that it also damages the chromosomes and mechanisms responsible for the health and functionality of your immune system.
When our immune system is compromised, it’s easy to catch every little virus that comes along. It also makes it harder for our bodies to fight off disease and cancer since our immune cells are our front line defense against all things unhealthy.

Scientists have found a promising link between vitamin D and breast cancer, with the vitamin shown to reduce breast cancer risk. However, they say their findings only apply to vitamin D in supplement form, according to Reuters.
Link Shown Between Vitamin D and Breast Cancer Risk Reduction
Researchers found that women who consumed vitamin D in a pill had a 24 percent lower risk of developing breast cancer. But those who got their vitamin D in their food didn’t see the same results. While they don’t say why they think this is, it could be because those using supplements are simply getting more of the vitamin on a daily basis.
The study, published in the American Journal of Clinical Nutrition, looked at 3,101 breast cancer patients and 3,471 health women, analyzing their diet and supplementation habits. There was no link established between dietary vitamin D consumption (or calcium consumption) and breast cancer. The link was only obvious in women taking more than 400 IU (international units) of vitamin D every day.
The researchers say more work is needed to determine exactly how much vitamin D is needed and to determine how it works. However, we do know that breast tissue cells have receptors for vitamin D, “raising the possibility that the nutrient could help regulate the division and proliferation of these cells.” And while the researchers don’t draw a connection between vitamin D and breast cancer when the vitamin comes from food sources, including the vitamin in a diet for breast cancer patients via foods naturally rich in vitamin D in addition to supplementation will only boost prevention.
Interestingly, the research gives no attention to getting vitamin D from the sun. It’s estimated that the body of the average light-skinned person creates about 20,000 IU of vitamin D3 (the most concentrated form) after one 30-minute, total body exposure to the summer sun at noon. In a darker skin person, the amount of D3 produced is about 10,000 IU.
You don’t need to sunbathe for hours to accumulate vitamin D, but getting outside for some sunshine during the day will increase the body’s natural creation of vitamin D, providing a wealth of vitamin D health benefits that could even reduce your risk of cancer.

A team of researchers looking into why cancer cells are so resilient accidentally stumbled upon a far more important discovery. While conducting their research, the team discovered that chemotherapy actually heavily damages healthy cells and subsequently triggers them to release a protein that sustains and fuels tumor growth. Beyond that, it even makes the tumor highly resistant to future treatment.
Reporting their findings in the journal Nature Medicine, the scientists report that the findings were ‘completely unexpected’. Finding evidence of significant DNA damage when examining the effects of chemotherapy on tissue derived from men with prostate cancer, the writings are a big slap in the face to mainstream medical organizations who have been pushing chemotherapy as the only option to cancer patients for years.
The news comes after it was previously ousted by similarly-breaking research that expensive cancer drugs not only fail to treat tumors, but actually make them far worse. The cancer drugs were found to make tumors ‘metasize’ and grow massively in size after consumption. As a result, the drugs killed the patients more quickly.
Known as WNT16B, scientists who performed the research say that this protein created from chemo treatment boosts cancer cell survival and is the reason that chemotherapy actually ends lives more quickly. Co-author Peter Nelson of the Fred Hutchinson Cancer Research Center in Seattle explains:
“WNT16B, when secreted, would interact with nearby tumour cells and cause them to grow, invade, and importantly, resist subsequent therapy.”
The team then complimented the statement with a word of their own:
“Our results indicate that damage responses in benign cells… may directly contribute to enhanced tumour growth kinetics.”
Meanwhile, dirt cheap substances like turmeric and ginger have consistently been found to effectively shrink tumors and combat the spread of cancer. In a review of 11 studies, it was found that turmeric use reduced brain tumor size by a shocking 81%. Further research has also shown that turmeric is capable of halting cancer cell growth altogether. One woman recently hit the mainstream headlines by revealing her victory against cancer with the principal spice used being turmeric.
This accidental finding reached by scientists further shows the lack of real science behind many ‘old paradigm’ treatments, despite what many health officials would like you to believe. The truth of the matter is that natural alternatives do not even receive nearly as much funding as pharmaceutical drugs and medical interventions because there’s simply no room for profit. If everyone was using turmeric and vitamin D for cancer (better yet cancer prevention), major drug companies would lose out.

[NaturalNews] A few months ago, a simple breakdown in communication between doctors led to the death of a 12-year-old boy in New York. Approximately 100,000 people die each year as a result of errors in hospitals, according to a decade-old national panel. In addition to breakdowns in communication, patients continue to be harmed or killed by medical shortcuts and inadequate training. Germs and errors combined make going to the hospital the fourth leading cause of death in this country.
Other large industries, such as the airline industry, have come to rely on a series of safety checklists that act as a safety net. The Infallible Doctor complex has prevented the medical community from following suit. There are hundreds of cases that have been publicized of a similar nature: unfathomable mistakes (such as operating on the wrong body part) at medical facilities, resulting in ridiculously obvious solutions (identify the correct body part before starting the procedure), that are then ignored or found to be ineffective.
The New York boy was sent from the hospital with a raging infection, and neither his personal doctor nor his family were notified of his lab results. Last week, four months after his death, the medical center involved has decided to adopt new procedures in response, such as doctors should be notified immediately of abnormal lab results, and the hospital should call the patient and his doctor if he has already been sent home. Really? This is what they came up with after four months? Has the medical establishment gotten so large, so bureaucratic, that they need to form Common Sense committees and procedurize basic, common communication and human courtesies?
It’s not stupidity or maliciousness that leads to the shocking problems in the medical industry. It comes from the culture of an institution. Who owns the responsibility to make sure common sense is observed, that communication happens between collaborating doctors and facilities? Are we ready to demand that doctors realize that they too are human, and need some checks and balances to protect patients, as well as themselves?
Conflict of interest
Cancer is a billion dollar industry. Almost every proposition regarding cancer put on any ballot, passes. With so much money, Big Pharma and their lobbyists in Washington have far too much control and influence on the medical system in America. And their profits depend on America’s ill health. The medical industry went from merely dysfunctional to actually harmful when the Supreme Court ruled on the Citizen’s Untied case, giving personhood status to corporations. Now it reflects the corporate culture of caste system privilege, enslavement to corporate product and profit, along with indifference to the lower classes. Medical mishaps are merely opportunities for more treatment.
The Hippocratic Oath, historically taken by physicians, physician assistants, and other healthcare professionals upon completion of their credentials, swears to practice medicine ethically and honestly. It says, in part, that the practitioner swears to “never do harm to anyone.” It goes on to swear against “deadly medicine” and not “cutting for stone” – a.k.a. invasive surgery. How could anyone possibly keep this oath in the current system? What prescription does no harm? What invasive procedure is completely harmless?
In a world with a rich history of safe, effective, inexpensive medical alternatives, the establishment seems to think medicine isn’t viable unless it is a synthetic, toxic pill made by unscrupulous pharmaceutical giants. And even with the overwhelming evidence that the medical culture has devolved to be more about money and power than curing illness, we are now required to be a part of the broken, ineffective, dysfunctional mess.
The awareness that you and you alone benefit from your own health should motivate you to self-education and exercising your right of personal choice. Medical “science” tries to convince us that there is only one treatment for any given health challenge, but that is simply untrue. But you have to be willing to stand against the authoritarian dissent of the establishment and its followers; go against the flow, and accept the personal responsibility of your own health. It’s either that or get in the chute with the other sheep.

[NaturalNews] It is time for the truth to be told about Susan G. Komen for the Cure. The organization is, flatly stated, engaged in fraud. Funded by drug companies and mammogram manufacturers, the organization preys upon women in order to grow its own financial power while feeding female victims into the conventional cancer industry grinder.
All across America, men and women participate in “run for the cure” events, raising tens of millions of dollars each year that go into the hands of Komen for the Cure. What these people don’t know is that much of that money is spent on “free” mammograms. Those mammograms, in turn, actually cause breast cancer because they subject women to high doses of ionizing radiation.
The Susan G. Komen scam, in essence, is to raise money that’s used to give women cancer and create a financial windfall for the very same companies that financially support Komen in the first place. “The Komen Foundation owns stock in General Electric, one of the largest makers of mammogram machines in the world. It also owns stock in several pharmaceutical companies, including AstraZeneca,” reports Tony Isaacs at NaturalNews (http://www.naturalnews.com/027307_cancer_breast_ACS.html).
“DuPont, another huge chemical company and major polluter, supplies much of the film used in mammography machines. Both DuPont and GE aggressively promote mammography screening of women in their 40s, despite the risk of its contributing to breast cancer in that age group. And while biotech giant Monsanto sponsors Breast Cancer Awareness Month’s high profile event, the Race for the Cure, it continues to profit from the production of many known carcinogens.” (http://www.tbyil.com/breast-cancer-deception.htm)
Komen’s corporate partners include General Mills, Zumba Fitness, Walgreens, The Republic of Tea, REMAX, New Balance, American Airlines, Bank of America, Ford Motor Company, Dell and many more (http://ww5.komen.org/corporatepartners.aspx).
The bottom line? Komen deceives women while powerful corporations rake in the profits. This isn’t merely my own opinion. Two prominent doctors, in an article published in the British Medical Journal, have sharply condemned Komen for the Cure for lying about the “benefits” of mammograms.
Komen ads are false, say scientists
“The world’s largest breast cancer charity used misleading statistics and deceptive statements about mammography to promote breast cancer awareness and screening,” stated scientists. (http://www.medpagetoday.com/HematologyOncology/BreastCancer/34030)
Their names? Steven Woloshin and Lisa Schwartz, directors of the Center for Medicine and the Media at Dartmouth Medical School in Hanover, New Hampshire.
They join a growing number of other doctors and medical professionals who now see Komen for the Cure as a fundraising fraud and are going public with detailed accusations against Komen’s deceptions.
In the recently published BMJ article, Woloshin and Schwartz accused Komen of lying in its promotional propaganda for the 2011 Breast Cancer Awareness Month. In advertising, Komen falsely claimed the 5-year survival rate when breast cancer is caught early is 98%, while only 23% when not “caught early.” This is how Komen tricks women into getting more mammograms which cause more cancer — by claiming “early detection saves lives.” But it’s not science; it’s pure propaganda. (See below.)
According to study authors Woloshin and Schwartz, Komen willfully ignored “a growing and increasingly accepted body of evidence [showing] that although screening may reduce a woman’s chance of dying from breast cancer by a small amount, it also causes major harms.”
Here’s an image published by the British Medical Journal, detailing how Komen for the Cure is lying about mammography:
Here’s what the data actually say
Komen for the Cure is in the business of fear mongering. They want everyone to be scared out of their minds that breast cancer is going to strike down all the women in their life. And in order to deal with the fear, all you have to do is give more money to Komen.
It’s sort of like an old-school evangelical group that asks for donations and says you’ll be healed if you just “believe,” but instead of claiming to heal people with the power of faith, the Komen cult claims to heal women with the power of ionizing radiation.
In reality, the actual 10-year risk of a 50-year-old woman dying of breast cancer is about half a percent: 0.53% (http://www.medpagetoday.com/HematologyOncology/BreastCancer/34030).
With mammograms used to detect breast cancer tumors, that 10-year risk of dying from breast cancer moves ever so slightly downward to 0.46%.
In other words, the real risk reduction of dying from breast cancer by receiving mammograms is only 0.07% — seven women out of 10,000.
How mammograms kill women
Seven out of 10,000 is a far cry from the fear-mongering levels that Komen propagandizes. It’s not quite the cancer apocalypse that Komen makes it out to be, huh? And in the mean time, Woloshin and Schwartz explain that anywhere from 20% to 50% of women who receive mammograms for a decade of their lives will have at least one “false alarm.”
These false alarms often lead to women being treated with deadly chemotherapy cocktails. These expensive drugs enrich the very same drug companies that donate money to Komen for the Cure. This is all part of the cycle of fraud that exploits women’s bodies for profit, all while conducting this sick fraud with the message of “finding a cure,” emblazoned with pink ribbons. The magnitude of the deception in all this is pathological… even criminal.
“The Komen advertisement is deceptive in another way: it ignores the harms of screening,” say Woloshin and Schwartz. “Between 20% and 50% of women screened annually for a decade experience at least one false alarm requiring a biopsy. Most importantly, screening results in overdiagnosis. For every life saved by mammography, around two to 10 women are overdiagnosed. Women who are overdiagnosed cannot benefit from unnecessary chemotherapy, radiation, or surgery. All they do experience is harm,” they write.
That harm often comes in the form of unnecessary chemotherapy that poisons women but financially benefits the drug companies. Here’s another article on NaturalNews which also supports this conclusion:
Also read my previous article, “10 Facts about the Breast Cancer Industry You’re Not Supposed to Know”
“Women need much more than marketing slogans about screening,” wrote Woloshin and Schwartz. “They need — and deserve — the facts. The Komen advertisement campaign failed to provide the facts. Worse, it undermined decision making by misusing statistics to generate false hope about the benefit of mammography screening. That kind of behavior is not very charitable.”
The article goes on to emphasize that mammograms are a wash, offering no net benefit to women’s health:
The benefits and harms [of mammography] are so evenly balanced that the National Breast Cancer Coalition, a major US network of patient and professional organizations, “believes there is insufficient evidence to recommend for or against universal mammography in any age group of women.”(http://www.knowbreastcancer.org/controversies/mammography-screening/)

Cancer-busting chemotherapy can cause damage to healthy cells, which triggers them to secrete a protein that sustains tumor growth and resistance to further treatment, a study said Sunday.
Researchers in the United States made the “completely unexpected” finding while seeking to explain why cancer cells are so resilient inside the human body when they are easy to kill in the lab.
They tested the effects of a type of chemotherapy on tissue collected from men with prostate cancer, and found “evidence of DNA damage” in healthy cells after treatment, the scientists wrote in Nature Medicine. Chemotherapy works by inhibiting reproduction of fast-dividing cells such as those found in tumors.
The scientists found that healthy cells damaged by chemotherapy secreted more of a protein called WNT16B which boosts cancer cell survival.
“The increase in WNT16B was completely unexpected,” study co-author Peter Nelson of the Fred Hutchinson Cancer Research Center in Seattle told AFP.
The protein was taken up by tumor cells neighboring the damaged cells.
“WNT16B, when secreted, would interact with nearby tumour cells and cause them to grow, invade, and importantly, resist subsequent therapy,” said Nelson.
In cancer treatment, tumors often respond well initially, followed by rapid regrowth and then resistance to further chemotherapy.
Rates of tumor cell reproduction have been shown to accelerate between treatments.

It’s no secret that berries of all kinds have numerous nutritional benefits—mostly due to their antioxidant concentration. The benefits of blueberries, for example, include lowering blood pressure and protection of the heart and liver. But a more obscure berry and fantastic anti-cancer food—black raspberries—may be effective at preventing numerous types of cancer, including colorectal.
Black Raspberries a Fantastic Anti-Cancer Food
According to a study published in the journal Cancer Prevention Research, mice were “engineered” to have intestinal tumors (a troubling thought). These mice were then fed a high fat, low calcium and vitamin D diet, referred to as a “high risk diet” over the following 12 weeks. Some of those mice were given a supplement so that 10 percent of their calories came from black raspberries.
Showing how black raspberries is a great anti-cancer food, the mice who were given the black raspberry addition had fewer tumors than those who were not. The growth of new tumors in these black raspberry mice decreased by 45 percent and the total number of tumors went down 60 percent.
Another group of mice, who was engineered to have intestinal inflammation, saw a similar decrease in new tumors and number of tumors by about 50 percent. The black raspberries actually reduced inflammation.
According to researchers, in order to have the same amount of black raspberries in your diet, you would have to eat four cups of fresh berries each day. While that’s a lot, there’s a good chance that even having a single cup each day could provide some benefit. Like scientists point out, these mice were made to have cancer, the human body is not, so you wouldn’t likely have to gorge yourself on them to have positive cancer-preventing benefits.
In addition to colorectal cancer, berries have also been shown to stop the cellular changes that lead to cancer. They’ve also been shown to stop the growth of esophageal tumors.
Because they can lower inflammation as well, researchers say it’s highly possible that they can protect against inflammatory diseases like cardiovascular disease.
The study, published in August 2008 in “Cancer Research” also found these berries are a great anti-cancer food, as compounds in black raspberries affect hundreds of genes so that cancer can’t as easily spread. Mice exposed to UVB radiation were less likely to develop skin cancer after being lathered in a gel containing black raspberry powder.
