Animals also have malignant tumors. What should we do if we accidentally eat them?

Cancer is a malignant disease that everyone fears. People with cancer are often fatal. However, cancer cells are actually not far away from us. A large number of cancer cells are produced in each of our bodies every day.

Each of us produces cancer cells every day, but not everyone will get cancer. The reason is that most cancer cells are killed by our immune system, and a small number of cancer cells lurk in our bodies. Because they are controlled by the immune system, they coexist with us for a long time in a harmless form. This is what is often called immune balance in medicine. Everyone has cancer cells in their bodies, and whether cancer cells can cause cancer depends to a certain extent on the person's immune ability. There have been some cases in medicine where a patient had a small amount of cancer cells in some of their organs, but it did not induce cancer. However, after the patient died accidentally, the donated organs caused malignant tumors in the recipient's body. The root cause is the failure of the immune system.

Cancer cells are not unique to humans. Most animals can develop cancer. This raises a question: since cancer cells also exist in animals' bodies, and some may have developed into small malignant tumors, what will happen if we accidentally eat them?

Eating a mouthful of cancer cells, this scene will make people's scalp tingle when they think about it, but it may also be something that each of us has done. Fortunately, we don't need to worry about it. When cancer cells enter our body from our mouth, a short process of tribulation will begin. There are difficulties posed by our digestive system waiting for it. From the mouth to the esophagus, to the stomach, from the duodenum to the colon, and then to the rectum, no level is easy to pass. Among these difficulties, there are both physical attacks and magical attacks. The so-called physical attack refers to the peristalsis of the digestive tract.

Our entire gastrointestinal tract is in constant peristalsis, and the purpose of this peristalsis is to help crush and digest food. The malignant tumors we eat will be broken down smaller and smaller in this series of frictions.

The decomposed tumor will encounter the next magic attack, which refers to the corrosion of digestive juice. Our digestive system will secrete a series of digestive juices to help us digest food, such as gastric juice and pancreatic juice. There is a great difference in their pH. The decomposed tumor will fully integrate with these digestive juices, and the structure will be completely destroyed. Finally, the soluble substances will be absorbed, and the rest will be excreted from the body. Can the cancer cells that people are afraid of be eliminated so easily? Yes. We think that cancer cells are very powerful because cancer is difficult to cure. However, there is no necessary connection between whether cancer is easy to cure and whether the cancer cells are powerful. In fact, cancer cells are very fragile.

In fact, compared with our powerful immune system, cancer cells are not worth mentioning at all. The key is that they are extremely hidden. Even at the molecular level, cancer cells are difficult to distinguish from normal cells. This leads to a result that it is difficult for our body's immune system to detect and attack cancer cells, so cancer cells will proliferate unscrupulously in our body.

The concealment of cancer cells not only confuses the immune system, but also brings great trouble to treatment. Because cancer cells are too similar to normal cells, it is difficult for us to kill cancer cells without harming normal cells, and the survival and proliferation capabilities of cancer cells themselves are stronger than ordinary cells. This is the basic reason why cancer is difficult to cure. However, although cancer cells have strong concealment and proliferation capabilities, they are not strong in themselves. Cancer cells that leave the human body are easily killed. If scientists want to culture cancer cells in vitro, specific conditions are required.

To culture cancer cells in vitro, a sterile environment must be prepared, otherwise the contaminated cancer cells will die quickly. Next, specific culture medium and serum are needed. In short, it is a very delicate thing. It is not as tough and strong as we imagine, and it can survive if we just raise it casually.

Cancer cells are so fragile that they cannot withstand the physical and magical attacks of our digestive system. Therefore, eating cancer cells will not cause any harm to health and there is no need to worry. Of course, this is limited to eating. The reason why eating cancer cells will not cause any problems is that our digestive system completely destroys the cancer cells. However, if cancer cells enter our body through other ways, the situation is completely different. For example, if we inject cancer cells directly into the body, we may get cancer. For ordinary people like us, the most effective way to prevent cancer is to enhance our own immunity and develop good living habits to stay away from diseases.
