Where do human cancer cells come from? There's a way to kill cancer cells, and it's simple

There was such a shocking saying in the circle of friends: everyone has cancer cells, and everyone can get cancer. Friends with a little medical knowledge can see that the person who said this obviously doesn't know what cancer cells and cancer are. However, this sentence has been used by many unscrupulous businessmen to promote some so-called The advertisement of "anti-cancer products" has also attracted many consumers.

Everyone has cancer cells, where do they come from?

If we really want to talk about it from the level of cells, I am afraid we have to start from the "alive" of people. Friends who have taken biology classes when they were young know that biology teachers often tell us in the first class that as long as people are alive, the cells in the body will keep dividing, one to two, two to four, and so on. As new cells are born, old cells decay and die, maintaining a virtuous cycle.

However, as the saying goes, there are no 100 days of red flowers, and there may be "problematic" abnormal cells in everyone's body. The professional saying is that there are more or less cells that may be genetically mutated in each person. These abnormal cells have become the potential of cancer cells. So we can say that everyone can get cancer, but it would be wrong to say that everyone has cancer cells.

Know that even abnormal cells are not equal to cancer cells. First of all, our body has a well-developed defense mechanism. Under normal circumstances, this mechanism will automatically check whether the cells have abnormal mutations. If they do, they will try to repair these mutations on their own. If they cannot be repaired, they will It will automatically activate a powerful tumor suppressor gene p53, and then start the cell's self-destruction program, causing abnormal cells to die through various pathways.

Secondly, even if cancer cells are actually born, they will be "targeted" by immune cells. Immune cells are like policemen, and they will always track the movement of cancer cells. If your immune system functions normally, immune cells will successfully remove cancer cells. Cells beat and knock them out of the body. Of course, if your immune system is not functioning properly, such as when you are old, your immune cells will also "retire". At this time, if cancer cells make a comeback, the body may be overwhelmed and slowly develop into cancer.

Maybe many people think that China is a country with a high incidence of cancer, but in fact, China's cancer incidence rate ranks around 70th in the world, and the places with a high incidence of cancer are all developed countries, such as Denmark, which ranks first, and Denmark, which ranks second. France, Australia, Belgium, etc., and these countries have a common feature, that is, their average life expectancy is also at the forefront of the world, so age has always been an important factor in the incidence of cancer. In general, the incidence of cancer rises sharply after the age of 50 for both men and women.

However, although the incidence of cancer in China is not too high, there are many hidden cancer risks around us. Take smoking as an example, a single puff of cigarettes can bring 78 kinds of clear carcinogens, which will lead to the death of lung cells. When cells die, new cells will be produced at the same time. Lung cells will continue to divide new cells and repair the lungs. More cell division increases the possibility of cell mutation, which increases the probability of the birth of cancer cells. In addition, those carcinogens add fuel to the fire. People who smoke are prone to lung cancer.

Exercise may kill cancer cells

After looking at it from the beginning, I believe everyone can find that the key to killing cancer cells is whether the human immune system is strong or not. Some foreign researchers have published research in authoritative academic journals. They found that in mouse experiments, exercise can directly shrink tumors, and the immune system function of mice that insist on exercise is much stronger than that of mice that do not like exercise. After that, more studies have shown that exercise can stimulate the body's immune system, activate more immune cells, and continuously improve the body's immunity. Therefore, since we cannot change the growth of age, we can only use these additional means of exercise. Delay the decline of immunity and prevent the occurrence of cancer.

Therefore, whether it is from the perspective of cancer prevention, or from the aspects of promoting skeletal muscle growth, improving blood circulation, improving physical adaptability, stretching body and mind, cultivating sentiment, and relieving tension, exercise is obviously beneficial to our body. A lot is very beneficial, so in order to stay healthy and stay away from cancer cells, the whole family may wish to exercise together.
