If a person dies, the functioning of the body stops completely, and the cancer cells will die gradually, but if the cancer cells are extracted before the death of the person and continue to be cultured, then the cancer cells can be truly immortal. The most famous cancer cell is the HELLA cell, which is the cervical cancer cell of a black woman in the U.S. It has been 67 years since it was isolated in 1951, and has been propagated by scientists in vitro for more than 18,000 generations.

HELLA cancer cells are used in experimental research of various cancers, and its biggest feature in in vitro culture is that it can divide and reproduce infinitely, reproducing faster than ordinary cancer cells, and scientists have obtained a lot of valuable information from HELLA cells.For example, in 1956, scientists found that HELLA cancer cells reproduce faster in space; in 1984, scientists used HELLA cancer cells to prove that HPV virus induces cancer; in 1986, scientists infected HELLA cancer cells with HIV and studied the pathogenesis of AIDS; in 1989, scientists discovered the secret of unlimited reproduction of cancer cells from HELLA cancer cells, which have telomerase enzyme, which can replenish the loss of telomeres on chromosomes during cell division. In 1989, scientists discovered the secret of infinite reproduction of cancer cells from HELLA cancer cells, cancer cells have telomerase, which can replenish telomere loss on chromosomes during cell division, and the degree of telomere loss determines the number of generations of reproduction, and telomeres can reproduce indefinitely if there is no loss of telomeres; in 1993, scientists infected HELLA cancer cells with the genetic material of Mycobacterium tuberculosis, and learned how the bacteria attack human cells.The Hella cancer cell has contributed greatly to the advancement of science, although its ownerHarrietta Lacks is dead, but her cells live on, possibly for hundreds and thousands of years, even to the end of the human race.

Here is something to say: sugar in human body is the main nutrient of cancer cells, some cancer patients want to starve cancer cells to death by hunger strike, but this does not starve cancer cells to death, so they make themselves malnourished, cancer cells in the process of frantic reproduction if the nutrient is not enough will rob the normal cells of the nutrients, so starvation of cancer cells is an unscientific practice.

Cancer cells are actually mutated human cells, only that their growth has become uncontrolled. They keep growing by seizing nutrients from the human body and keep growing newborn tumor blood vessels around the tumor cells to deliver nutrients to the tumor cells. Therefore, once the human body dies, the blood in the blood vessels will stop flowing and stop supplying energy and oxygen to the cancer cells, and the cancer cells will gradually wither and die. There is an old Chinese saying: if the skin does not survive, the hair will not be attached to it. It is the same reason.

Cancer cells do have a stronger ability to survive compared to ordinary cells. Because the number of divisions of cancer cells is not controlled, for certain unique cancer cells, if humans provide the right conditions, then such cancer cells can also survive - even to the extent of being inexhaustible. For example, if cancer cells are extracted and cultured before a person's death, the cancer cells can be truly immortalized. One of the most famous cancer cells is the HELLA cell, which is the cervical cancer cell of a black woman in the U.S. It has been 67 years since it was isolated in 1951, and has been propagated by scientists in vitro for more than 18,000 generations.

Cancer cells are a kind of cells that have no independent survival ability and cannot even stay outside the body for a little while, much worse than all kinds of bacteria and other microorganisms. Tumor cells can only attach to the human body and keep on growing destructively, so once they lose their survival environment, they will surely die. The image is that the cancer cells steal nutrients madly, kill their hosts, and then die passively. Unlike the power of microorganisms such as Mycobacterium tuberculosis and HIV, the genes of these microorganisms have evolved over a long period of time and are able to produce a lot of defense mechanisms, which can withstand harsh living environments such as cold, heat, dryness and humidity, and remain resilient even outside the body, thus making them contagious. From this, we can see that although cancer cells are rampant, they are in fact very fragile and must attach themselves to living organisms to survive.
