The Mystery
How does the cancer process begin? Do you think scientists know? Do you think your doctor knows? Don’t be so sure. In fact, what most scientists researching the disease, and a whole lot of doctors treating it, think they know, is wrong. Let me explain.
The current belief in medical research holds that
cancer begins with a genetic mutation, and that carcinogens cause cancer
by injuring genes. However, the huge effort and billions of dollars invested
by the National Institute of Health (NIH), private foundations, and
pharmaceutical companies in searching for injured genes in cancer has
produced few discoveries and little benefits to the public. The reason for
this limited success is very simple. The cause of most cancers is not an
injured gene.
Hunting for Genetic Mutations and Cancer
A little background:
1. What is a gene? A gene is a creature that produces a protein, like a
football player who produces yards during games.
2. What are proteins? Proteins are the major building blocks of cells,
yards in our example.
3. What is a mutated gene? A mutated gene is an injured player. Very rarely a
mutation is beneficial to the organism (X-Men, Evolution, Lance
Armstrong?). In all other cases, the mutation is damaging the gene. Think
of the effect of a serious knee injury on our football player.
Current belief:
The current belief in medical research holds that most cancers are caused by exposure to carcinogens, and that carcinogens
begin the cancer process by injuring certain genes. This belief is so ingrained that the National Human Genome Research Institute (NHGRI), an institute at the NIH, recently stated that "all cancers are based on genetic mutations in body cells." Moreover, a search on PubMed, the search engine for scientific papers in life science, with the keywords "Mutation" AND "cancer" produced 86,490 papers and 12,238 reviews. Mutation hunting is also a big business. Look at the NIH budget allocated to discoveries of genetic mutations, the number of biotech companies chasing genetic mutations, the magnitude of the licensing agreements between biotech and pharmaceutical companies aimed to utilize newly discovered genetic mutations, and the number of stories in the media on genetic mutations and their so-called "link" to disease. However, this huge effort and billions of dollars has produced few discoveries and little benefits to the public. The reason for this limited success is simple.
The cause of most cancers is not a mutated gene.
The story of the BRCA1 gene is a typical example of mutation hunting.
The Mystery of BRCA1
Genes, in general, produce proteins, which are the building blocks of cells. The concentration of proteins is tightly regulated. A mutated or
injured gene produces an abnormal concentration of its protein, which may lead to disease. In 1994, Mark Skolnick, PhD, discovered the BRCA1 gene (BRCA1 is short for BReast CAncer
1). Following the discovery, scientists observed a low level of the BRCA1
protein in breast cancer tissues. This observation created a lot of excitement. At the time, scientists believed that they were on the verge of finding the cause of breast cancer. The reasoning was that breast cancer patients must have a mutated BRCA1 gene, which would explain the decreased production of the protein, and the
development of tumors.
In the United States, 180,000 cases of breast cancer are diagnosed each year. However, the BRCA1 gene is mutated in less than
5% of these cases.
In more than 95% of
breast cancer patients the gene is not mutated, the gene is not injured,
no scars, no limited motion, nothing.
So here is the mystery. If the gene is not mutated in the great majority
of the breast cancer patients, why are the tumors showing low levels of
the BRCA1 protein? The BRCA1 gene is not unique. Many normal (perfect
shape, non-mutated) genes exhibit a mysterious abnormal (increased or
decreased) production of proteins in cancer.
These observations prompted Dr. Raxit J. Jariwalla to conclude in his European Journal of Cancer paper
that "genetic alteration is not the initiating event of cancer." (Jariwalla RJ. Microcompetition and the origin of cancer. Eur
J Cancer. 2005 Jan;41(1):15-9)
So, if a genetic alteration
(also called genetic mutation or genetic injury) is not the initiating event
of most cancers, what is the initiating event?
Want to help?
Send a letter to the Director of the National Cancer Institute (NCI), or
to the Director of the National Institute of Health (NIH) demanding that
they allocate funds for further research on the starved gene discovery.
Without your letter, it might take years until the conservative NIH will
respond to the discovery.

The Center for the Biology of Chronic Disease (see
http://www.cbcd.net/) Rochester, NY
We are a 501(c)3 not-for-profit organization that specializes in researching the biology of chronic disease. By "the biology of chronic disease" we mean the original disruption that causes the disease, and the sequence of events that lead from the original disruption to the development of clinical symptoms. We hope that once the biology is clear, pharmaceutical and biotech companies will be able to formulate drugs that reverse the effects of the disruption, and therefore cure the disease, or even block the original disruption, and therefore prevent the disease from developing in healthy individuals.
