I'm in conflict right now with my children's pediatrician. Basically, my children were "fired" as patients because I decline the Chicken Pox vaccine. Apparently, both children are also one booster behind on their MMR (although I did not decline that). Before I blindly accepted the threat of losing the pediatrician, I had to be sure of the facts. So I began looking into components in the Chicken Pox vaccine (and others). Through Children of God for Life (http://www.cogforlife.org/vaccineListOrigFormat.pdf) I found that both the MMR and Chicken Pox vaccine are created using aborted baby cells and/or embryonic stem cells. I also found that one of the primary drivers for developing and promoting the Chicken Pox vaccine is convenience. Apparently parents can't take off work long enough to care for their itchy and scratchy children. However, my children's vaccination woes aren't huge topic of this post. My specific mutations (that I know of), vaccines, and cancer are the topic.
While searching for information to give to a friend about her children's vaccinations, I came across some interesting information. Apparently one of my mutations, MTHFR, can increase my already increased risk of breast cancer (thanks to My BRCA1 mutation). In addition to this twice increased risk of breast cancer, vaccinations can increase the MTHFR mutation's negative effects (http://cebp.aacrjournals.org/content/17/10/2565.full) I'm not certain which variant of the MTHFR mutation I have. Since it was discovered as a potential cause for my 4 miscarriages out of 6 pregnancies, I do know I have problems from it.
This mutation creates problems in carriers after vaccinations. Vaccines have heavy metals as carriers in them. Usually, the body can easily eliminate these heavy metals through the normal function of the MTHFR gene (http://en.m.wikipedia.org/wiki/Methylenetetrahydrofolate_reductase). However, defective MTHFR genes do not effectively eliminate these heavy metals, causing them to build up to toxic levels in the body. Additionally, the MTHFR gene is responsible for methylation or de-methylation of folic acid to its biologically active form-folate. When defective, methylation and/or de-methylation causes either a deficiency or an excess of various chemicals in the body. These chemicals, when built up and not effectively processed can lead to decreased immunity and increased susceptibility to various problems.
Some indicate vaccinations (http://vactruth.com/2011/12/30/3-filthy-truths-about-vaccines-cancer/) and problems from the heavy metals (http://www.naturalnews.com/030211_heavy_metals_cancer.html) and foreign material can also increase risk of breast cancer in all people, but most noticeably those with a BRCA1/2 mutation. Since BRCA1/2 are genes that code for a particular tumor suppressor gene in the breasts (http://en.m.wikipedia.org/wiki/BRCA1), carriers have an increased risk of breast cancer. Adding the increased levels of heavy metals, excess or deficiencies of folic acid/folate, to an already increased risk of breast cancer may just explain why I was diagnosed with breast cancer a full 20 years before my own mother. Even my youngest known relative with "female" cancer was a full 14 years older than I was at diagnosis. Along with other environmental factors yet unknown (although many implicate GMOs, processed foods, pollution, deodorants, and other seemingly random factors) and increased vaccinations (with their heavy metals and other foreign materials), these two mutations and their effect on the body my risk of cancer was probably closer to tripled than the average person. Yet, rare would be the doctor (of any sort) that would put all this together and actually say it out loud to a patient.
