Why hasn't a cure for cancer been found yet?

First, what is cancer? The basis of this disease is the abnormal division of body cells. The "wrong" cells continue to divide further and form larger and larger masses of body tissues. So, cancer is an uncontrolled growth (spread) of body cells. Cancer can appear in any type of cell. Since there are different types of cells, there are different types of cancer.

Hundreds of different types of cancerous tumors can form in the human body. It turns out that cancer is not one disease, but a whole family of diseases. And therein lies one of the problems associated with finding a cure for cancer. One approach to solving this problem is to find out the factors that contribute to the development of cancer. Scientists also need to know how these factors cause normal cells to become cancerous. By finding out this issue, they hope to find ways to prevent this disease.

Another area of research is the development of drugs capable of destroying cancer cells already in the body in the same way that modern antibiotics destroy bacterial cells. Scientists have discovered many factors that contribute to cancer, such as certain chemicals.

Governments around the world have taken steps to eliminate the possibility of such chemicals being ingested by humans and generally to reduce all contact with them to a minimum. Such measures really help prevent cancer. Since there is a close relationship between cancer cells and viruses found in some animals, more and more scientists are coming to the conclusion that many types of cancer are caused by viruses. But how the virus contributes to the appearance of cancer cells in the human body - this question has not yet been answered.

The search for the causes of cancer is very difficult, but significant progress is being made in this area. It is possible that in the end it will be found that different forms of cancer have little in common with each other. Or, on the contrary, it will turn out that the action of different pathogens of this disease is basically the same. But at this stage, we don't know all that yet.

Random interesting fact from the Great Encyclopedia:

Where are the highest and where are the lowest places on the territory of the former USSR?

The highest point in Russia is the Elbrus peak, 5560 meters high, north of the Main Caucasian Range. On the territory of the USSR, the peak of Communism in Tajikistan (7495 meters) rose the highest, and the lowest point was the Karagie depression in Kazakhstan (134 meters below sea level) to the east of the Caspian Sea. The highest point in Ukraine is Mount Hoverla in the Carpathians (2061 meters), the lowest point is the Arabat Spit at sea level. In Russia, the shore of the Caspian Sea is located below all, which is 26 meters below the level of the world ocean.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Fifth chlorophyll 02.05.2011

Australian biologists from the University of Sydney have isolated a new type of photosynthetic pigment, chlorophyll, from seaweed.

So far there have been four known. The first, the most common, is found in all plants, from the lowest to the highest. It works mainly on blue and red light, absorbing them and reflecting green (which is why almost all plants look green). Two more types of chlorophyll with a slightly different absorption range are found only in lower plants. The fourth type of chlorophyll is present in cyanobacteria (they are also blue-green algae), the range of its work is shifted to the red end of the spectrum.

A new type of plant pigment from Australian algae assimilates the energy of short-wave infrared, that is, thermal rays. This is the first such case in the plant kingdom.
