1. Malignant overthrow as a stochastic process of biological evolution
... Cancer cells adapt to treatment
2. Anti-cancer immunity from the evolutionary point of view
Finally, let's point out that people are very well aware of the anti-cancer immunity. Man is a naturally long-lived animal against cancer that is better equipped than most vertebrates. Throughout our lives, our immune system detects and destroys dozens of tumors without bothering to inform us.
... large and long-lived animals and K stratego boot like humans naturally have high anti-cancer immunity
... the fact that cancer has a high share in the causes of death of a population is to be considered as a civilization and medical success
3. Cancer as a living organimus - Helacyton gartneri
The development of cancer is like the emergence of life. Somatic ba or stem cells of the body (except the germinal line) do not fulfill the definition of life (read Flegr). In contrast, cancer cells fulfill this definition, although their ecological niche is extremely narrow - the single host organism. The biologist (google name) has noticed that the cancer cell cells used in the research have spread this niche to laboratory dishes in the culture rooms of science institutes, and to his glory has decided to describe HeLa cells as a eukaryotic taxon with everything, including the Latin name Helacyton gartner. This, of course, has caused a turbulent discussion of all concerned, from taxonomies to evolutionary biologists. Also, except that Helacyton belongs to Eukaryotes, it is unclear what higher taxa are there - Hominidae , and it probably will not.
There is also a diametrical shift in the definition of health with cancer. From a host's point of view, healthy cells are those who do what they have and do not divorce without permission. From the point of view of cancer as a living organism, the cancer cell is the healthier, the more malignant it is.
Cancer cells can be understood as individuals of self-indulgence, selfish, undesirably unwashed, and body of a foreign organism. This idea is not original. I am by no means the first biologist who uses this idea for the sensational style of writing. Evolutionary biologist Leigh van Valen even went so far as to see heLa cells as a living organism and named Helacyton gartleri . From a practical point of view, it is important for oncologists and patients with cancer to understand that the power of evolution acts on cancer cells.
Cancer cells adapt to treatment ...
... just like bacteria. So the rule of sufficient doses and antibiotics is also valid for tumors only in the longer term.
Tumors are out of control and begin to grow relatively autonomously, although under normal circumstances, cells are able to detect and repair their mutation, or possibly apoptosis at least.
At some stage, tumor growth, which is manifested by, for example, pressure, ischemia , and cell death ( necrosis ) at the tumor site, notices the immune system that attempts to destroy the tumor.
How quickly does evolution affect cancer cells?
About twenty times slower than bacteria. So, for bacteria, we have 2-4 weeks to treat first-line antibiotics than they (in the case of non-cures) adapt to the bacteria, we have cancer cells for over a year. Therefore, when dosing natural drugs with anticancer effects, care should be taken to ensure a sufficient dose during the first year of treatment in order to achieve the greatest cumulative effect until the tumor adjusts to the treatment.
Cancer cells - a drawback
They are very similar to our own cells.
Cancer cells - an advantage
They look like our own cells. Unlike microbial parasites, they have conscience. Cancer cells are considerably less problematic than cells under the control of viral infection. Ordinary cancer cells are basically good, have good intentions, they're just a little messy (so long as they do not end up in the process of malignancy altogether). They can even say hormonal therapy or hear from the immune cells. Again, here is the law of evolution: the most inhumane survive :-)
Complete ban on treatment ... F alun Gong ... I was unlikely to complain that the government of the PRC is limiting and shutting down ... I got my interest only when I found out that the leader is an anti-medical practitioner
Compared with other animals, we have excellent anti-cancer defenses
