What are the Causes of Cancer in Humans and in Animals?

Posted on February 1st, 2017

Wikipedia defines cancer as a “group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body”.

Wikipedia also lists the possible signs of cancer in humans.

. A lump or growth

. Abnormal bleeding

. A prolonged, unrecognized cough

. Undetermined weight loss

. A change in the texture and quantity of a bowel movement.

Wikipedia also lists the most common causes for cancer in humans.

. Tobacco causes 22 %

. 10 % is caused by obesity, poor diet, lack of exercise, and drinking


. Many other factors may also be involved.

In animals, the signs of cancer are very similar to those signs and symptoms that occur in humans.

However the following causes of cancer seem to be gaining in prominence in the animals that develop cancer:

. Genetics

. Stress

. Endocrine immune imbalances

. Anesthesia

. Vaccinations

. Phytoestrogens (plants that contain estrogen)

. Xenoestrogens (Chemical, estrogen mimickers).

. GMO foods

. Heavy metals

. Radiation

. Toxins

. Pesticides

. Glyphosates and many more environmental inputs.

Unfortunately we need to realize that our environment is changing for both humans and for animals and usually not for the best.

Due to the inbreeding of many different kinds of animals, particularly canines and felines, there are now families of canines and felines that are failing due to the development of cancer and many different autoimmune diseases.

This seems to be occurring due to the fact that many of our canines and felines are being bred for physical features and not for function.

They are often bred for size, other physical features, including structure and color.

This procedure has caused their gene pool to become to close.

When their gene pool becomes to close, certain endocrine immune values are changed that allow for the development of cancer. Over the years I have noted this, based upon doing endocrine immune blood tests on 90,000 canines, felines and equines.

The clinical problem that occurs and allows for this avalanche of diseases and cancer to occur comes from the production of a deficient or defective cortisol.

Genetics seem to be the main cause for this to happen, however our animals, as we, are also exposed to the other various, damaging environmental exposures, which are listed above.

Cortisol, which is a vitally important, regulatory hormone, is produced in the middle layer adrenal cortex.

When a deficient or defective cortisol is produced by this middle layer adrenal cortex, it will cause an excessive amount of adrenal estrogen to be produced by the inner layer adrenal cortex. For more information on this mechanism, please Google Estrogen or Cancer with my name.

When this happens, the excessive amounts of adrenal estrogen will cause the following;

. When estrogen is exposed to normal tissue in a Petri dish, the normal

   tissue will grow.

. Excess estrogen will invalidate the body’s use of thyroid hormones

. The excess estrogen will deregulate the immune system so the B and

   T-lymphocytes will not function to protect the body against bacterial

   and viral diseases.

. The excess estrogen will cause the B-lymphocyte to reduce

    its production of immunoglobulins (antibodies). When this occurs,

   and the amount of mucous membrane antibody that is produced is

   below 58 mg/dL in animals and 68 mg/dL in humans, malabsorption

   of many nutrients and supplements will occur, including especially, a

   cortisol supplement.

   NOTE: This might be one reason why a hospitalized patient does well

   when receiving intravenous or intramuscular injections and upon

   going home and taking the same medication orally, they begin to

   develop their disease again.

Over the years, the medical profession has been concerned with increased amounts of estrogen causing cancer.

Of interest, excessive amounts of adrenal estrogen are rarely considered.

Over the years, I have wondered why this has occurred.

Recently, on the internet, I found an article discussing the history

of estrogen. Apparently in the mid 1940’s, a prominent human laboratory made the statement for the medical profession, that the human body only produces three types of estrogen, which are estradiol, estrone and estriole. There was no mention of adrenal estrogen.

My studies in animals and in a few studies in humans have all identified an elevated adrenal estrogen in every cancer patient.

If you Google The Results of an International Convention for MD Oncologist etc. with my name, you can see the results for 3 human patients that all had elevated adrenal estrogen and had cancer or an immune mediated thyroiditis.

NOTE: My animal studies for cancer and autoimmunity were all done on animals that had their ovaries and testicles removed before being tested. The purpose of doing this was to help rule out other forms of estrogen that might have been produced and measured.

For humans, LabCorp can do the adrenal estrogen test and they have it listed as total estrogen. There are also other humans laboratories doing total estrogen, but their normal values are very questionable.

A postmenopausal woman should have a total estrogen of 40 pg/ml

A human male should have a total estrogen of 80 to 115pg/dL

For all other patient levels, please contact LabCorp directly.

For animals, National Veterinary Diagnostic Services can do an adrenal estrogen test and provide normal levels for canines, felines, equines and humans.

For more information on the feedback mechanism that effect the production of cortisol, please either go to drplechner.com or Google

Endocrine Immune Surveillance or ACEIS, which stands for Atypical Cortisol Estrogen Imbalance Syndrome, with my name.

Hopefully my clinical veterinary studies might stimulate some interest in the problems and diseases that excessive amounts of in adrenal estrogen can cause.
