Does probiotics is helpful for the problem of cancers?(2)
Published April 16,2024

Now,let us check the probiotic therapy. 

The relationship between probiotics and cancer cells should start from pathology of cancer. The quantity of our body calls are limited. When one cell dies, another one will replace it at all. This is how the whole body works. In cancer cases, it is not a bad thing that cell begin to multiply uncontrollably. The problem is that they do a lot of things harmful to health: releasing toxins, disrupting the normal function of tissues or cells, and consuming a lot of energy at the same time.     

Gene mutations make it difficult to control the growth of cancer cells , which is caused by a variety of reasons. First , cells may be attacked by viruses and so on , which are adsorbed on normal human cells and then inject their DNA into the DNA of normal cells . As a result , they may (but not forever ),disrupt the normal function of healthy cells, causing mutations.

It is possible that mutations are caused by organic mutation –induced compounds , just a chemical or substance that can cause genetic change . To realize this , you can imagine that each individual cell is made up of four letters-G,A ,T , and C, in a precise way , such as ,GATCCCAAG. Each small segment of a single DNA looks like this ,even after the cell division. This is how DNA (sometimes called a genetic code ) pass on from generation to generation. But if the mutated substance turns Tinto C ,the code reads GACCCCAAG. Such a small change may even determine the life and death of the cell. 

So how does the mutation happen?We can know that everything is the masterpiece of cells by confirming everything,just like the example we give above -DNA tells us by arranging letters. Some compounds can even enter these letters and damage them . These compounds are collectively called organic mutation or carcinogens.When DNA works, the cells are happy and normal .It will split several times ,and die within a predetermined time . This is what cells do .But , as part of a normal function,such as replication,it can be said that the cells DNA must be “cracked ”(for many reasons, most of DNA must be tightly bound together, and one of the substances that binds them together is actually protecting it from carcinogens

This cracking increasea the probability of harmful compounds attacking DNA .The more DNA is cracked ,the more likely it is to be attacked and hurt .The degree of survival depends directly on the order of the four letters , which may take turns to br attacked by toxic substance, inducing organisms mutation substances and carcinogens. 

So, what role can probiotic play in it? In fact , they act in a variety of ways. First , they create substances which interact with defensive substances and decode them. Second , probiotics can absorb toxic substances and process them through a variety of ways to weaken their toxicity. Third , probiotic help our body stay away from bacteria .This ,of course ,is beneficial ,not only because harmful bacteria,such as the notorious colibacillus,(which causes spoilage of meat ,can produce substances that make the body sick or even life-threatening) but also because some harmful bacteria adsorb harmless substances and turn them into carcinogens.Through the above effects, probiotic can prevent and crack the attack of toxic substanceson DNA ,so as  to eliminate gene mutation and achieve the effect of cancer prevention and treatment.    

Probiotics achieve the purpose of protecting the body by transferring bacteria.The internal space of human beings is very limited. In fact, in order that beneficial or harmful bacteriacan play a role in the health of the human body ,it has to takes some time to procrastinate every ostensibly. That is to say , bacteria must attach themselves to the inner layer of the gastrointestinal tract  ,this process is called bacterial adhesion, some of which occupy certain areas of the gastrointestinal tract. For example, lactobacillus is always willing to live in the small intestine, while bifidobacterium in the intestine likes to live in the rectum.  

Probiotics experience normal life and death like cells . They may mutate as they age so they can no longer solidify together. In this way, any harmful bacteria passing through here may adhere to the probiotic position, so that probiotics have no place in the intestinal layer. Once these bacteria have a foothold here, there is only one thing they can do –to play their harmful role.  

Probiotics can play an anti-tumor role in the following ways :  dissolve or adsorb carcinogens to reduce their toxicity, stimulate the body’s immune system to resist the multiplication of cancer cells , resist the reproduction of intestinal rotten cells through improving the environment of intestine to prevent the formation of intestinal carcinogens, produce compounds that can inhibit the growth of tumor cells or kill metabolites of harmful bacteria . The metabolite or extractive of probiotics has a remarkable effect : science and technology reduce the opportunity of chemical mutation; it degrade fecal enzymes, nitrosamines which can cause carcinogens; and it can also prevent some bacteria destroying DNA. 

Don’t worry , we can add more probiotics to correct this. It sounds easy ,but actually it is not ,because normal gastrointestinal tract has about 400 kinds of probiotics. To help people recognize , some companies have launched some of the most beneficial bacteria, about 10 to 20,which can be found normally in healthy people , and some studies have identified many natural foods containing probiotics.  

There exist three main views in the scientific field about principle of probiotic cancer prevention: one is that probiotics stimulate the immune system to attack cancer cells; the other is that probiotics can prevent carcinogenic chemicals from acting; and another holds that probiotics can cause cancer cells to apoptosis themselves. 

Many studies have shown that probiotics have direct antitumor effects. Let’s look at some cases.

*In an animal experiment about the antitumor properties of probiotics, the antitumor effect of a particular yoghilomycetes was tested.In this experiment, one group of mice ingested a certain amount of foraminifera every day, while the other group did not ingest any probiotics . All of these mice were subcutaneously injected with nitrosamine, a tumor-inducing substance. The results showed that by the 26th ,the mice fed with probiotics significantly reduced the incidence of tumors, and by the 40th week, the mice in the group fed with probiotics had a much lower  incidence of tumors than those in the contrast group . This is because the probiotics stimulate the production of certain immune components that can kill and inhibit tumor growth, such as IL-LA and tumor necrosis factor a. In another study of prbiotics and tumors, the researchers found that the probiotics stimulated the growth of Bifidobacillus in the intestines of mice fed inulin and fructose oligosaccharide. 

*Ian Roland, a professor of human nutrition at the university of Northern Ireland, has confirmed by clinical trials that a beverage containing probiotics can reduce the likelihood of damage to the gut-cell gene and help prevent colon cancer. The results were published in 《Clinical Nutrition of United States》 journal in 2007. 

*Dr .Roland conducted the experiment in 80 volunteers and divided them into two groups, one group have been treated with colon cancer and the other group were diagnosed with intestinal polyps as a precursor to cancer. Roland asked each patient to drink a drink containing probiotics and inulin. Inulin cannot be digested in the upper intestinal tract, so it can reach the large intestine and become the energy source of colorectal probiotics. Roland kept the volunteers drinking probiotic drinks for 12 weeks and compared the changes of cell carcinogenesis before and after drinking through two lived tissue sections. The results showed that the carcinogenesis of the first group of volunteers treated with colon cancer had no change before and after drinking probiotic drinks, but those who had intestinal polyps had less carcinogenesis and less proliferation after drinking inulin and probiotic drinks.

*According to a research project led by Professor Da Qiao JingXiong ,department of Medicine, University of Tokyo, Japan, the risk of bladder cancer was reduced by 50% in people who are used to drinking lactic acid bacteria.The professor compared the 180bladder cancer pacients in 7 reginal hospitaals in Japan with 445 healthy people,and conducted 81 questionnaires on the drinking of lactic beverages in the previous 10-15 years. After a series of statistical treatment (deviation caused by sex, age, smoking, etc.), the results were as follows: the risk index of bladder cancer was 1.0 in people who did not drink lactic acid bacteria drinks, and only 0.4 in those who drank 1 to 2 times a week.
