Vitamin D supplementation may be able to slow or even halt the progression of the most dangerous variety of breast cancer, according to a study conducted by researchers from Saint Louis University and IRBLleida, Spain, and published in The Journal of Cell Biology. In addition, the researchers isolated biomarkers that could help physicians identify women that could benefit from vitamin D treatment.
The researchers came to this discovery by identifying, for the first time, one of the molecular pathways that leads to the variety of breast cancer known as triple-negative. This cancer is more likely to affect younger women, and is most resistant to treatment.
Scientists have known for some time that a malfunction of a tumor-suppressing gene known as BRCA1 can lead to the development of breast cancer. This gene is part of the cellular defense system by which the body ensures that any damaged DNA is not passed on to new cells, using mechanisms such as screening DNA for errors and sending cells carrying damaged DNA into hibernation or even programmed cell death. This is an important cancer-preventive role, because an accumulation of DNA damage can lead a cell to the out-of-control replication associated with cancerous tumors.
BRCA1 plays a role in screening DNA and repairing double-strand breaks, a particularly dangerous form of damage. It also plays a role in verifying that DNA has been replicated and transferred properly to new cells. When BRCA1 fails, it may lead to the development of breast cancer, and often the particular variety that is negative for receptors of two hormones and a protein: estrogen, progesterone and HER2. Because such tumors are not dependent on these external factors for growth, they are harder to “starve” and kill.
The vitamin D link
In South Korea, scientists used a magnetic field to get cancer cells to actually self-destruct. The body removes old, defective, and infected cells through the process of programmed cell death (PCD), or apoptosis. In apoptosis, the rejected cell responds to certain signals sent by the body by fragmenting. Immune cells then consume these fragments. The magnets help trigger apoptosis. When apoptosis fails, however, rejected cells divide uncontrollably, developing tumors.
Magnets Induce Apoptosis
Professor Jinwoo Cheon of Yonsei University in Seoul and a team of scientists conducted experiments on bowel cancer cells using magnetic fields to induce apoptosis. They attached iron nanoparticles to antibodies, which bind to “receptor” molecules on tumor cells. These molecules cluster when the magnetic field is applied, triggering the “self-destruct” signal and thereby apoptosis. In the experiment, over half of the bowel cancer cells were destroyed when the signal for apoptopic clustering came into effect. Untreated cells remained unaffected and unharmed.
Big Pharma’s Response?
Sheryl Crow says that her benign brain tumor may have been caused by cell phone use. Doctors found the tumor earlier this year after the singer, aged 50, began having difficulty remembering lyrics.
Crow reassured fans that the tumor is benign, but the latter remember her battle with breast cancer in 2006. What has puzzled many fans is that she attributes her tumor to excessive cell phone use, although no one should actually be surprised. “I [was] worried I had an early [onset] Alzheimer’s,” she told Katie Couric on her new show, Katie.
Public Left in the Dark About Radiation Dangers
“There are no doctors that will confirm that. [But] I do have the theory that it’s possible that it’s related to that,” she told Couric. “I [used to spend] hours on the old archaic cell phones.”
Industry and media have collectively perfected the art of keeping the greater public in the dark. In fact, Tawkon released a mobile app last year that estimates radiation levels produced by smart phones based on antennae strength, headset or speaker phone use, and baseline figures provided by manufacturers. But what did technology giant Apple do? Ban the app from its App Store.
Studies on Cell Phones as Carcinogens
Meanwhile, research by Greek scientists shows that cell phone radiation changes vital proteins (up to 143) in the brain. Researchers found that 143 proteins in brain areas like the hippocampus, cerebellum, and frontal lobe were negatively impacted by radio frequency radiation over a period of 8 months. A total of 3 hours of cell phone exposure were simulated over the 8 month time period, and the results showed that many neural function related proteins’ functional relationship changed the for worse.
Natural News ~ Ever since chemotherapy was introduced into the practice of western medicine, doctors and oncologists have been trying to answer this nagging question: Why does chemotherapy seem to work at first, but then cancer tumors cells grow back even more aggressively while the body becomes resistant to chemotherapy?
It turns out that chemotherapy damages healthy cells, causing them to secrete a protein that accelerates the growth of cancer tumors. (http://ca.news.yahoo.com/chemotherapy-backfire-boost-cancer-growth-st…)
This protein, dubbed “WNT16B,” is taken up by nearby cancer cells, causing them to “grow, invade, and importantly, resist subsequent therapy,” said Peter Nelson of the Fred Hutchinson Cancer Research Center in Seattle. He’s the co-author of the study that documented this phenomenon, published in Nature Medicine.
This protein, it turns out, explains why cancer tumors grow more aggressively following chemotherapy treatments. In essence, chemotherapy turns healthy cells into WNT16B factories which churn out this “activator” chemical that accelerates cancer tumor growth.
The findings of the study were confirmed with prostate cancer, breast cancer and ovarian cancer tumors. This discovery that chemotherapy backfires by accelerating cancer tumor growth is being characterized as “completely unexpected” by scientists.
The chemotherapy fraud exposed
Ginger, a cousin spice of super anti-cancer substance turmeric, is known for its ability to shrink tumors. Astoundingly, it is even more effective than many cancer drugs, which have been shown to be completely ineffective and actually accelerate the death of cancer patients. Commonly consumed across the world in small doses among food and beverage products, the medicinal properties of ginger far surpass even advanced pharmaceutical inventions.
The subject of one study based out of Georgia State University, whole ginger extract was revealed to shrink prostate tumor size by a whopping 56% in mice. The anticancer properties were observed in addition to ginger’s role in reducing inflammation as well as being a rich source of life-enhancing antioxidants. But what about cancer drugs? Could this simple spice really topple the advanced pharmaceuticals that are often touted as the ‘only option’ for cancer patients by medical doctors?
