Parabens are added to everything from shampoos and deodorants to processed foods and pharmaceutical drugs in order to inexpensively extend shelf life and improve product stability. But a new study out of the University of Reading (UR) in the UK has found that, based on tests conducted, nearly every single woman with breast cancer has one or more paraben chemicals in her breast tissue, suggesting a possible link between the chemical and the disease.
According to the UK's Daily Mail, Dr. Philippa Darbre and her team from UR gathered tissue samples from 40 women who were undergoing mastectomies for breast cancer between the years of 2005 and 2008. The team took four different tissue samples from each woman at separate times, which collectively totaled 160 samples, and performed an extensive analysis on each of their contents.
In the end, the group found that 99 percent of the breast tissue samples contained at least one type of paraben, while 60 percent contained at least five. And while the presence of parabens in cancer-infected breast tissue does not necessarily imply that the chemicals are responsible for causing the disease, it sure does lend suspicion to the notion that parabens could be a potential culprit.
"The intriguing discovery that parabens are present even in women who have never used underarm products raises the question: where have these chemicals come from?" asked Dr Darbre after observing that even women who did not use typical paraben-containing products still had the chemical in their breast tissue. "The fact that parabens were present in so many of the breast tissue samples does justify further investigation."
In a separate study, the US Centers for Disease Control and Prevention (CDC) found that nearly every human urine sample tested contained parabens. This is particularly concerning, since research compiled by the Environmental Working Group (EWG) suggests that parabens are linked to causing organ system toxicity, reproductive and fertility problems, birth and developmental defects, and endocrine (hormone) disruption. (http://www.ewg.org/chemindex/term/563).
When shopping for personal care products and food, be sure to read all ingredient labels carefully to avoid unnecessary exposure to parabens. High-quality personal care products, for instance, will often contain helpful labels indicating that they do not contain parabens.

CANCER AND OXYGEN
Cancer cells are anaerobic.
Cancer, above all other disease, has countless secondary causes. There is only one primary cause: the replacement of normal oxygen respiration of our bodies cells by an anaerobic cell respiration. Dr. Warburg also said when cells cannot feed off oxygen they feed off themselves by fermenting their own sugars in a process that gets out of hand and continues under its own inertia, called cancer. Dr. Otto Warburg Two-time Nobel Laureate Winner of the Nobel Prize For Cancer Research.
Growth of cancer cells is initiated by a relative lack of oxygen known as cellular hypoxia. This process cannot begin or continue in an oxygen rich environment.
In the February, l956, issue of Science, pp. 309-3l4, Dr. Otto Warburg, reported that all cancer cells produce excessive or inordinate amounts of lactic acid and all have impaired mitochondria. These are compartments in all cells that house the Krebs cycle. Approximately 70 percent of the total energy needs of the body are derived from the Krebs cycle. Beyond this cycle a process called glycolysis contributes approximately 20 percent of the body’s total energy needs and the mono-phosphate shunt approximately l0 percent (taken from textbook Practical Physiological Chemistry). Living cells cannot grow, reproduce, or survive without sufficient amounts of energy to carry out their multitude of metabolic functions.
It may be of interest to note here that the Krebs cycle can extract energy from carbohydrates, fats, or amino acids. Glycolysis and the mono-phosphate shunt, however, extract energy only from glucose or carbohydrates. It is also important that the Krebs cycle and the mono-phosphate shunt require oxygen for their metabolic functions whereas glycolysis, whether in normal or cancerous cells, functions without oxygen or anaerobically.
When Dr. Warburg made his discoveries concerning the excessive production of lactic acid by cancer cells, little was known then about the thirteen enzymes that function in the Krebs cycle and the 11 enzymes that function in glycolysis. This is why neither he nor the cancer community at that time realized the potential therapeutic significance of his lactic acid, mitochondria discoveries, and the crucial role they could play in the treatment of all cancers.
Dr. Warburg found that normal cells derive most of their energy from respiration (aerobically or with the use of oxygen), whereas cancer cells derive most of their energy anaerobically or from fermentation (without the need of oxygen). This implies that normal cells derive most of their energy though the Krebs cycle (aerobically), whereas cancer cells derive most of their energy from glycolysis (anaerobically).
At the time, Dr. Warburg, as well as the cancer community, all believed that cancer cells produce large amounts of lactic acid only because they are deprived of sufficient oxygen to carry out their metabolic functions. The lack of knowledge then concerning the functions of the Krebs cycle and glycolysis, thus prevented medical science from understanding that cancer cells production of excessive lactic acid signifies that they rely almost exclusively upon carbohydrates or glucose for their major energy and that proper dietary modification, such as a diet low in carbohydrates, can prove a viable adjunct to conventional medicine in the treatment of all cancers.
Studies recently reported by scientist’s working in both cancer and AIDS research now explain how cancer cells can produce inordinate amounts of lactic acid because of injury to their mitochondria, even in the presence of oxygen.
It has become known, for example, that the activities of the mono-phosphate shunt are increased more than ten-fold in cancer cells (Journal of the National Cancer Institute, Dec. 6, 2000, p. 1926), compared to normal cells. As mentioned above, the mono-phosphate shunt functions aerobically or with oxygen. This implies that if cancer cells were being deprived of oxygen, we would not find an increase in the activities of the mono-phosphate shunt but a reduction in activities instead.
At the time, Dr. Warburg could not see the immediate therapeutic potential of his discoveries. But the technology he developed allowed him to measure the amounts of oxygen cancer cells consumed and the amounts of lactic acid they produced. When he found that cancer cells were producing such large amounts of lactic acid and that their oxygen consumption was greatly reduced, he assumed this was all caused by an insufficient supply of oxygen. He did not know at the time that if the mitochondria were defective within cells, they could not use their Krebs cycle and that this would cause them to produce excess lactic acid even though the cells were not deficient in oxygen.
In the December 3, l997, issue of the Journal of the National Cancer Institute, p l764, appears the following, “Most solid tumors rely almost exclusively on the anaerobic metabolism of glucose as their main energy source, with most being converted to lactate. Glucose uptake and lactate release by human colon carcinomas have been found to exceed the peripheral tissue exchange by 30-fold and 43-fold, respectively.” This implies that colon cancer cells burn 30 to 40 times more glucose for energy than normal cells.
Dr. Warburg reported in his l956 article that normal liver cells burn more than l00 times more oxygen than cancer cells. This implies that the normal cells derive most of their energy from the Krebs cycle and not from glycolysis, as is the case with cancer cells.
A PET scan detects cancer cells, it identifies them by the amounts of glucose they consume. This is further evidence of the ravenous appetite cancer cells have for glucose.
Knowing that cancer cells require such large amounts of glucose to grow, reproduce, and even to survive, placing cancer patients on a low carbohydrate diet not only makes good sense but also good medicine.

Understanding Cancer
Cancer does not develop for some unknown reason. Once you understand why and how it develops, and learn how to support your body so that it may more effectively fight cancer, it may never be too late to get healthy again. (No matter what type, they have the same underlying causes.) Cancer is a natural process where, to put it simply, an overworked and weakened immune system cannot kill it as fast as it is multiplying. Toxin, carcinogens, radiation, even viruses, combined with an unhealthy internal environment , and in conjunction with a weakened immune system, cause more cells to turn cancerous, and allows them to thrive.
You must change your internal environment to one in which cancer cannot thrive. Just as we couldn't live on Mars with no oxygen, cancer can't exist in cells where there is enough oxygen. Unfortunately, all too often our cells are low in oxygen. Fortunately it is possible to increase the levels of oxygen in cells, thus, making your body's internal environment a place where cancer can't easily survive.
Immune System Support for Cancer
Cancer is a perfectly natural process. A very small percentage of cells in every person who has ever lived turn cancerous. And the body usually gets rid of those cancerous cells before they do harm. This process has been going on for eons. It is only when more cancer cells are being created than the body can get rid of that the problem comes. With increased toxins, viruses, carcinogens, etc. our immune systems have become significantly overworked and weakened.
The underlying cause of all cancer, no matter what type, may have been discovered by Otto Warburg over 50 years ago. He actually won two Nobel Prizes for work proving cancer is caused by a lack of oxygen respiration in cells. He stated in "The Prime Cause and Prevention of Cancer" that the cause of cancer is no longer a mystery, we know it occurs whenever any cell is denied 60% of its oxygen requirements.
"Cancer, above all other diseases, has countless secondary causes. But, even for cancer, there is only one prime cause. Summarized in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar.
