There is a lot of good information on the web relating to cancer, and non-traditional ways to prevent or fight it. Here is just some of what has interested me.
One is the sugar issue since it has been established that cancer cells thrive on sugar and do not survive well on ketones. This is one way in which a HFLC diet may prevent cancer or be used as part of cancer treatment.
It is interesting that in one research project, a researcher did cell sampling on corpses of 50 year or older accident victims, and found that all of them had numerous cancer cells. This tells us that development of cancer cells is common, but our bodies control them via our immune systems. This suggests we look to immune function, but also tells us that biopsies done today are not scientifically valid for determine the need for treatment.
Another interesting fact is that often we have elevated blood levels of Alpha-N-acetylgalactosaminidase (nagalase), an enzyme that turns off proteins that otherwise would activate macrophages in our immune system. Nagalase is produced by many types of cancer cells, viruses, and by a fetus, all of which would be attacked and killed by macrophages if they didn't have this defense of their own. For some reason, some kids with autism have unusually high levels of nagalase in their blood, perhaps related to immune system dis-function.
There is one cancer treatment originated in Japan, and currently being used in Germany and Switzerland which claims a good success rate. The protein that activates macrophages, GcMAF, is extracted from healthy people and injected into people with cancer to attack the cancer cells; once the cancer cells are knocked back, the body's own production of this GcMAF protein takes over, and as long as the precursors for production of GcMAF are available, we then control newly formed cancer cells.
Gc protein is in the albumin family. It is also known as Vitamin D binding protein, and as Gc-globulin. It is encoded by the Gc gene. Gc protein binds to Vitamin D to transport it to target tissue. When it is transported to the liver, it is acted upon by T cells and B cells by the deletion of two of its three sugar molecules. This makes the protein GcMAF or Gc macrophage activating factor, which then switches on macrophages when they are needed to fight cancer and viruses. Nagalase prevents Gc protein from becoming GcMAF by removing all three sugar molecules from the Gc protein (deglycosylates it).
Since Vitamin D is part of the process adequate blood levels of Vitamin D are important.
There is a significant relationship between some cancers and low Vitamin D levels, so if you don't live on or near the equator, or even if you do, but do not get enough sunlight, or don't supplement with Vitamin D, your 25(OH)D blood levels will be low and you will have an increased risk. Some of the researchers suggest keeping your 25(OH)D level between 50 and 60 nl/mL which might require 5,000 IU a day of Vitamin D in the late autumn, winter, and early spring when direct sunlight is inadequate. Most people have woefully low levels of 25(OH)D; people with dark skin are particularly low because the dark skin blocks UVb sunrays from penetrating the skin to turn cholesterol into Vitamin D.
Then, there is the seed oil issue. Seed oils were promoted as a supposedly healthy replacement for saturated fats. Seed oils like corn, soybean, safflower, sunflower, canola, etc. are polyunsaturated which means that these molecules are missing some hydrogen atoms that saturated fats have. In order to maintain some stability at least two sets of carbon atoms in the polyunsaturated carbon chain will double bond, but this bond is weak and easily broken. Exposure to oxygen can break the bond, i.e., oxidize (burn) the fat, and this is damaging, particularly when these fats are part of our cellular structure. This oxidation produces toxic aldehydes, one of which is 4-HNE which is associated with Parkinson's. There is correlation between cancer and the presence of polyunsaturated fats in cells. In addition it is know that polyunsaturated fats suppress immune function, and inhibit production of thyroid hormones, both of which contribute to cancer.
On the issue of low thyroid hormones, metabolism is dependent on the thyroid hormones so if we are deficient in these hormones, our cellular respiration is low; many systems then don't work adequately. Cells do not die at a normal rate, and we are more prone to cancerous mutations. Thyroid hormones are essentially iodine bound to tyrosine, the tyrosine being a carrier and the iodine being the active agent. Selenium is involved in the process of regulating the amount of active and inactive thyroid hormone, so it is important in the process too.
(As to weight gain, farmers have long known to fatten livestock with grains high in polyunsaturated fats, and that saturated fats make livestock lean.)
Not only does iodine regulate cellular respiration and programmed cell death, it also acts as an antioxidant in binding polyunsaturated fats to slow their oxidation. If iodine is bound up by polyunsaturated fats, it is not available to regulate cellular respiration and programmed cell death.
Is it any wonder that researchers are claiming that Vitamin D deficiency, Iodine deficiency, Selenium deficiency, and sugar contribute to cancer, and that therapies based on the understanding of these factors are more than the snake oil that conventional medicine claims.
These concepts are only part of the picture, but enough to consider something besides the failed poison, burn, and cut approach of chemotherapy, radiation, and surgery.
