Mesothelioma is a lung cancer with a very high mortality rate. After a person is sick, he has difficulty breathing and has a cough. Once he is diagnosed, he will die in less than a year. For decades, the inhabitants of this place have always been heart-wrenching and living in fear. When they get up every day, the first thing they want to know is whether they start coughing. If they find a cough, they understand that they are on the road to no return. If a coughing person walks down the street, everyone will look at him with sympathetic eyes and scream in horror: the next one is probably his turn. People in neighboring villages are afraid of people in cancer villages because they fear that the disease will spread. Some residents have fled, but most people have no economic strength to change to a new home. Others believe that it doesn’t matter where you flee, because it is destined.
Kaponi is here to learn about the prevalent mesothelioma in this area.
With what he has known in the past, mesothelioma usually occurs in people who often deal with asbestos, such as construction workers. Because asbestos is a refractory, corrosion-resistant silicate mineral that used to be used in construction and road construction. It is its excellent corrosion resistance, which makes asbestos dust become very deadly when inhaled into the human lungs, because these dusts are not easily decomposed and absorbed by the normal cleaning mechanism of the human body. Over time, it will lead to chronic inflammation, and finally develop into cancer. Since the discovery of this “bad track” of asbestos, many countries have now banned the use of asbestos as building materials.
But here, the cause of mesothelioma seems to be somewhat confusing. There is no asbestos mine near the cancer village. Although the materials used by the villagers to paint the walls contained asbestos, people in other villages painted the walls with the same paint, and the people there were fine.
After a long-term investigation by Kaboni, the answer finally surfaced. The cancer that caused cancer is actually this magnificent volcano. This is really “the beauty of human life”, the poisonous snake hidden under the rose.
It turns out that there is a fact that even the average doctor knows very little: although there are only six kinds of silicates in the name of asbestos, in nature, there are about 390 kinds of silicates similar to asbestos. feature. The dust of these minerals is also very resistant to corrosion, so once they are sucked into the lungs, they are as dangerous as asbestos. One of these silicate minerals, called erionite, is not a problem in Cappadocia. The volcanoes in the area are carved out of this soft stone by the rain. Unfortunately, three cancer villages were built near the bare ground zeolite rocks, which are easily mined and processed and used by many villagers to build houses.
Also related to heredity
Things may end here, but there is still a question: Why do families live in the same environment, some families are more likely to develop mesothelioma, as if the whole family was cursed by God, and their members died one by one. And other families are safe and have an incredible resilience to this cancer?
In order to figure out this, Kaboni conducted a house-to-house investigation in the village: ask them what they eat and drink on a daily basis, where they work, the history of individuals and families, and so on. On this basis, he proposed a preliminary hypothesis: in addition to frequent exposure to erionite, if a person carries a gene, the risk of illness will rise sharply. This gene must be more common in the local area, because this area is remote and closed, and many families are married by close relatives.
After returning to the United States, Kaponi also investigated two families with high prevalence of mesothelioma. Their members did not seem to be exposed to asbestos or erionite. He found a special gene for mutation in them. This gene usually acts as a “brake brake” for cell division, that is, when the cell divides to a certain extent, it stops it from dividing. But after the mutation, the brakes failed, and the cells continued to split, leading to tumors.
However, this mutant gene does not appear to be responsible for mesothelioma in residents of Cappadocia because their genes are not abnormal. Therefore, Kaponi has speculated that it may not only have one gene but also many genes to increase the risk of mesothelioma. This explains why some people are prone to mesothelioma when they are slightly exposed to asbestos (or other corrosion-resistant silicate minerals), while others deal with asbestos all the year round, even when playing asbestos as snowballs throw each other. But still healthy.
Although Kaboni has not identified the remaining pathogenic genes so far, his work at least makes people realize that erionite is as dangerous as asbestos, and erionite is generally formed in the role of volcanic ash and water, and is more mountainous in the world. Rocky areas are very common, and people often use it to pave the way, build parking lots and playgrounds. Now that it is known to be dangerous, the cancerous villages of Paduasia have moved to places far away from the shale rock, while the rest of the world has begun to eradicate pavements, parking lots and playgrounds with terracotta, replacing them with safer materials. .
In addition, people are now beginning to realize that in addition to asbestos and erionite, there are about 400 kinds of fibrous silicate minerals in nature that may also cause mesothelioma, and we need to take measures to prevent it.
