Today's topic: Why don't blue whales get cancer?
Cancer cells do not have a proper tissue structure, and when the volume is large to a certain extent, the internal cells cannot obtain enough nutrients and starve to death. Therefore, the cancerous tissue will not grow until it grows to a certain extent, and for the blue whale, this is a small pimple, which has long been fatal to humans
For a blue whale, a tumor is like a pimple if you have a pimple
An increase in the number of cells, an increase in antioxidant and immune stress, and an increase in somatic mutations that accumulate over time – don't all these factors increase the risk of cancer? Why does it become cancer-suppressing when it is placed on large mammals?
These are the disadvantages. Under such unfavorable conditions, genes that inhibit cancer are easier to screen
The reason for not getting to the point is that there are too few samples from the autopsy of the dead blue whale to conclude whether it will get cancer or not.
Tumors can grow to a large size, and the growth of tumors will also be accompanied by the growth of blood vessels, and tumors can also metastasize through adjacent blood vessels and lymphatic vessels throughout the body.
Do you mean a 10-ton 20-ton tumor?
Cancer is not afraid of how big your tumor is, after all, how big the waste is cut, and what cancer is most afraid of is spreading, so you can't find the real cause.
However, cancer cells will metastasize and metastasize to organs and tissues throughout the body, and then it will not be as simple as a tumor, but the collapse of the entire body system and the collapse of body functions
This brings me to another interesting point. Although whales are much larger than humans, the probability of getting cancer is about the same as that of humans. So the incidence of serious cancer outbreaks in whales is not as high as expected
The larger the animal, the longer it takes for all the cells in the body to renew once. The fewer the number of updates, the less likely it is to produce replication errors, and it is less likely to develop cancer.
Therefore, some people say that the discharge of nuclear wastewater does not affect any marine ecology, can you believe it?
It's a little unreliable. A person's self-perception is irrelevant to whether or not cells have been replaced. To use an analogy, you feel like you're breathing and using oxygen because you're reading a book, not because your cells are using oxygen. In the same way, whether a person feels himself or not has nothing to do with whether his brain cells are renewable.
The tumor is developing too fast, and the consumption is also huge, until it reaches a certain level, the host is consumed to death, the blue whale is big enough, and its own consumption is huge, and the life span of the blue whale is reached before the volume of the tumor reaches the consumption of the body
