Can animals get cancer? Which animals are not susceptible to cancer?

My last question, I can safely say, you got it wrong. They also come to MC's.

First, animals can get cancer.

Second, the multiple births of animals are determined according to the size of the individual and the structure of the uterus, and large herbivores (such as antelopes, cattle, horses, elephants, etc.) are usually one litter and one child.

Third, animals will also have menstruation, according to the ovulation cycle, the human reproductive cycle is about a year, with the improvement of living standards, it has usually been shortened to about 10 months (pregnancy plus recuperation cycle) The ovulation cycle is 1 month, probably because people are social animals, so the cubs born all year round will not cause the inconvenience of survival.

1. Sharks. Sharks are kept in closed seawater full of carcinogens ——— aflatoxin and will not develop cancer for several years. Because there is a substance in shark cartilage that can inhibit the growth of blood vessels in solid tumors and directly inhibit the growth of tumor cells, called angiogenesis inhibitory.

Scientific studies have shown that shark cartilage can increase the production of antibodies and activate important functional cells of the immune system in the body, such as T cells, B cells and macrophages. It is immune to almost all bacteria.

2. Ants Ants live in the dark, damp underground, yet they don't get sick. Because ants have antibacterial glands in their bodies, they have long-lasting specific immune functions, which are the first to inhibit staphylococci and other germs and prevent a variety of diseases. In addition, the formic acid secreted by ants also has a strong bactericidal effect.

3. Mosquitoes. Mosquitoes are multicellular organisms. The size of the mosquito depends on the species, although most are less than 15 mm. The weight is about 2, and one hind leg weighs only about that. The mouthparts are stabbing and suctioning, like a very thin syringe needle.

Mosquitoes have a rapid metabolism, food enters the body, is quickly digested and absorbed, and germs are excreted before they have time to multiply and cause disease.

4. Flies. Biologically, flies are completely deformed insects, and their life history can be divided into eggs, larvae (3 instars), pre-pupa, pupa, and celeryl tolerant adults. Although the lifespan of flies is only about 1 month, a female fly can lay 500-1000 eggs.

The antimicrobial active protein of the fly immune system is extremely bactericidal, and 1 ml can kill all bacteria and viruses in the body.

5. Bees. The body is small, cephalothorax is black, the queen bee is about long and about long, the body color is black or brownish-red, and the whole body is covered with black and dark yellow hairs. Bees contain a special substance - propolis, which has a strong inhibitory and killing effect on germs and molds.

The body length of the worker bee is about 11mm, the beak is about 5mm long, the dorsal plate of the ventral segment is black, with brownish-yellow rings, the abdomen of the middle bee in high latitudes and high mountainous areas is black, and the abdomen of the center in the low latitude and plain area is yellowish, and the whole body is covered with gray short villi.

There are two kinds of animals in the world that are not allowed to be cancerous, one is the shark that swims in the sea, and the other is the goose that runs on land.

Some scholars believe that sharks are one of the very few animals that cannot be cancer-free for life, and there may be some special substances in the body, which may help the body's immunity, but this is only a speculation and has not been confirmed by experiments. It is currently said that the reason why sharks are not cancerous may be related to lifelong exercise, sharks do not have swim bladders, and only by constantly exercising can they maintain a suitable depth, even while sleeping, otherwise they will sink to the bottom of the sea.

The goose is a species of ducks of the order Bird's class Gooseformes, and is the only grass-eating animal in the poultry to take dates, and rarely suffer from plague. The scientist of Ke Zexiao will not be cancerous if the cancer cells are hit on the goose.

It is very good to eat Sun Min's shark meat and goose meat, sharks and geese do not know what is on them, and they have not been studied yet, only that these two animals are not cancerous and have lifelong immune function!

The only animal that does not have cancer cells is a goose. The ancestor of the goose is the goose, which was domesticated by humans about three or four thousand years ago. It is bred all over the world.

Grass-eating, cold-tolerant, gregarious and disease resistant. It grows fast and has a longer lifespan than other poultry. It weighs 4 to 15 kg and has an incubation period of one month.

It inhabits near ponds and other waters, and is good at swimming.

Sharks must not be the cause of cancerThere are two kinds of animals that are not allowed to be cancerous in the world, one is a shark swimming in the sea, and the other is a goose running on land.

It is currently said that the reason why sharks are not cancerous may be related to lifelong movement, sharks do not have swim bladders, and only keep moving the sedan ridge to maintain a suitable depth, even when sleeping, otherwise they will sink to the bottom of the sea. The goose is a species of ducks of the order Bird's class Gooseformes, and is the only grass-eating animal among the poultry, and it is less likely to suffer from the plague of sail filial piety. Scientists hit the cancer cells on the goose to prevent cancer.

At present, people generally talk about cancer discoloration, and cancer threatens people's lives. Once you have cancer, the process is very painful, and the rate of cancer is not high. We humans get cancer, so can other animals get cancer like humans?

The answer is yes, cancer is not a disease specific to humans, animals in nature can get cancer, even plants cannot avoid cancer.

Cancer cells used to be normal cells, but they were mutated. There are many cells in our body, and cells will be renewed, so some cells in the body die and some cells are copied out every moment. For a normal cell, the DNA telomeres on its chromosomes will be damaged to some extent every time it replicates, and when it is replicated a certain number of times, the telomeres will also be damaged to a certain extent, and then the cell can no longer replicate.

However, cancer cells are different, they can replicate indefinitely, so that there are more and more cancer cells, it is constantly competing with normal cells for nutrients, and it also secretes some substances that cause diseases in the organism. When normal cells are deprived of nutrients and cannot work normally, the body becomes fragile and the substances secreted by cancer cells cause various problems in the body, and finally the organisms will be killed by cancer cells. This way of killing cancer cells is not only found in humans, but also in animals.

Almost all animals have a chance of getting cancer, but some of the few animals have a much smaller chance of getting cancer. Among the many animals, there are some lucky animals that are much less likely to die from cancer than humans and other animals, and elephants are typical examples. Scientists have found that elephants have a small chance of dying from cancer, mainly because they have a gene called TP53 in their bodies, and when normal cells mutate into cancer cells, the TP53 gene will be found in time, and then the mutated genes will be repaired, so as to kill the cancer cells in time.

In short, cancer is the enemy of all animals, and so far, animals still lose their lives due to cancer, and maybe in the future, humans can find a way to restrain cancer!

In fact, it is not only humans who are susceptible to cancer, but animals can also get cancer, because they sometimes have some cells in their bodies that are beyond control, so they are prone to cancer at this time.

Animals can also get cancer, animals have cells in their bodies, and when cells become cancerous, they will get cancer.

In fact, animals can also get cancer, but the lifespan of animals themselves is not long, so few animals can get cancer.

Cancer is a kind of disease, and both humans and animals can get cancer, but there are relatively few animals.

Humans get cancer, and animals get cancer. It's just that there is less research on cancer in animals on a daily basis, and we pay less attention to it. Cancer is a genetic disease in which a mutation occurs in a gene in the body that causes normal cells to evolve into cancer cells.

Mutations in the genes in animals can also lead to cancer in a certain environment or under the influence of certain carcinogenic factors.

China's cancer research department conducted a tumor survey on poultry and livestock. During the census, researchers dissected 269 domestic chickens and found that 11 of them had different types of cancer, including liver cancer, stomach cancer and malignant teratomy.

Scientists have found a strong correlation between the proportion of the same type of cancer in humans and poultry in the same area. For example, in Lin County, Henan Province, which has the highest incidence and mortality rate of esophageal cancer in China, the proportion of people who die from esophageal cancer each year is about, while the incidence of esophageal cancer in local chickens is about; In contrast, the two data for Fan County, an area with a low incidence of esophageal cancer, were as follows.

At present, medical research results have shown that one of the main causes of esophageal cancer is excessive consumption of foods containing nitrosamines and mycotoxins nitrosamine compounds. In areas with a high incidence of esophageal cancer, the content of nitrosamines in food and drinking water is much higher than in other areas. Poultry, especially domestic chickens, are fed by local grains, so the risk of developing similar digestive cancers is much higher than that of grazing cattle and sheep.
