Building the Immune SystemThe immune system is critical when fighting cancer. Theories behind some natural cancer protocols::

1) Kill microbes and parasites in the organs (this called a “liver flush”). These microbes and parasites are claimed to be responsible for weakening the organs and the immune system. These microbes and parasites in the organs also theorized to weaken the immune system because they intercept food and excrete highly acidic mycotoxins.

2) Energize the cells in the organs (and thus energize the immune system) by using electromedicine. Electromedicine is claimed to be the vehicle for removing microbes and parasites in the organs.

3) Supplements which are focused on helping the immune system.

4) Kill microbes in the bloodstream utilizing electromedicine.

5) Use enzymes (e.g. Kelley enzymes or proteolytic enzymes) to strip the enzymes off of cancer cells so the immune system can better identify the cancer cells.

6) Heavy metal chelation to build the immune system.

7) Special minerals to build the immune system.

8) Herbs (e.g. echinacea) to build the immune system.

9) Colon flushes to build the immune system as the colon harbors massive numbers of microbes and possibly parasites.

The immune system contains many different types of “cells,” however, only a handful of these white blood cells actually target and kill cancer cells. It should be the intent of a person with cancer to focus on treatments that quickly increase the count of the cancer-killing white blood cells.

There are the Killer T-Cells and the Helper T-Cells. Of course, the main cancer-killing white blood cell is the Natural Killer (NK) cell. Another frequently mentioned category of white blood cell are macrophages. B Cells are also frequently mentioned with regards to cancer, though they work more indirectly.

Obesity depresses T-cell response and movement of the macrophages. Cadmium (a heavy metal) slows down the speed of the B-cells' producing antibodies in the immune system. Lead (the heavy metal) slows T- and B-cell response. Mercury will be discussed next.

Not only is a weak immune system a major reason cancer patients have cancer, but once a person has cancer, the cancer itself can further weaken the immune system. Talk about a vicious cycle.

Cancer Suppresses The Immune System

Dental Amalgam

Mercury reduces the number of T-cells and reduces activity in the immune system. Cadmium, Lead, and Mercury reduce the activity and speed the macrophages, thus increasing susceptibility to infection. Saturated fat makes the cancer T-killer cells unable to recognize “self” cells gone badly.

Kill Microbes and Parasites In The Organs

If you read the “What Causes Cancer” article you know a theory behind the cause of cancer is a weak immune system which cannot keep up with killing new cancer cells. The reason the immune system is weak is claimed to be because of microbes and parasites in the organs.

This theory is based on the premise that by killing these microbes and parasites in the organs the immune system can function again and deal with the cancer cells.

Doing this is built-into some cancer treatments, but it is not built into others.

Beta Glucan

It is also necessary to provide nutrients specific to the immune system.

“Starting in the 1940's, researchers have investigated the nutritional benefits of Beta Glucan. Derived from broken cell walls brewer's yeast (Saccharomyces cerevisiae), Beta Glucan is a powerful immune stimulator, activating the macrophage in the immune system. In addition to these important functions, Beta Glucan is an effective antioxidant and free radical scavenger. Beta Glucan is a safe, non-toxic, and orally effective supplement for those who wish to enhance their immune system and promote healthy cholesterol levels.”

This is how Beta Glucan works:

Beta 1,3-D Glucan works by activating the macrophages, or immune cells, which trap and engulf foreign substances. These activated cells start a cascade of events that cause the entire system to be alerted and mobilized, in an entirely naturally activated sequence. This amplified immune system response helps speed up the recovery of damaged tissue, helps other substances like antibiotics, anti-fungals and anti-parasitics to work better, and helps the macrophages recognize and destroy mutated cells.”

The Pancreatic Enzymes

Generally, the first immune system building product that is mentioned in alternative cancer treatment circles are the pancreatic enzymes: trypsin and chymotrypsin. That is interesting because these enzymes do not build the immune system, but they do “clear the way” for the immune system to do its job.

“Digestive enzymes-also called pancreatic enzymes include three classes: proteolytic enzymes needed to digest protein, lipases needed to digest fat, and amylases needed to digest carbohydrates. In several conditions that cause malabsorption, such as pancreatic insufficiency and cystic fibrosis, doctors sometimes prescribe digestive enzymes to improve absorption of food.”

It is the proteolytic enzymes (i.e. proteases) that we are interested in here, and particularly trypsin and chymotrypsin. When they are done digesting the meat in the digestive tract (of course it is hoped that there is no meat in the digestive tract because virtually all cancer diets forbid meat, largely for this reason), they start to clear the proteins that surround cancer cells and clear the way for the immune system to kill the cancer cells.

The actual building of the immune system, for treatments such as laetrile therapy or the Kelley metabolic diet, is based on the theory that diet and supplements are key components of cancer treatment. As mentioned many times elsewhere on this website, the foods you don't eat are just as important as the foods that you do eat with regards to building the immune system.

Supplements necessary to be used with these types of treatments are zinc, Vitamin C, manganese, magnesium, selenium, Vitamin B, and Vitamin A, but especially zinc and Vitamin C.

Some of the cancer diets that are mentioned with immune system building treatments are good, but not great. An example of a cancer diet is the “Raw Food” diet, which focuses on foods that are known to kill cancer cells and build the immune system. The article on the Raw Food diet can be found at:

Another proteolytic enzyme that has seen promising results in treating cancer is bromelain. This enzyme comes from pineapples and is a major ingredient in the Raw Food vegetable drink (which includes whole pineapples).

A fourth proteolytic enzyme is papain.

Other Supplements: MGN-3 or MGN3
