The struggle between people and cancer has a long history and has been recorded for a long time. Now there are statistics. The process of human beings understanding cancer can be seen as a history of scientific and technological development, medical progress, and life improvement.
Past : I don’t know why I get sick, I’m scared of the disease, helpless, and turn to the gods and rely on miracles.
Later : I observed cancer cells and knew who was making trouble and how to stop them. Surgery and radiotherapy came in handy.
Later, : I understood the basic principles of carcinogenicity, various innovative therapies gradually emerged, and the methods of preventing and anti-cancer have become richer.
The current basic situation of fighting cancer is:
1. Cancer is generally on the offensive, the human body is on the defensive, and there are very few vaccines that can prevent cancer.
2. I have not fully understood the pathogenesis of cancer. In addition to hair and nails, cancer can develop throughout the body.
3. Cancer has not been conquered yet, but it can be prevented and controlled, and even let the cancer foci dormant and can survive for a long time with tumors.
But the working people know that the body cannot get cancer for no reason. It must be from daily life and is closely related to life. Some folk folk remedies and methods for preventing and anti-cancer are widely circulated, and there are many jokes that eating a certain food can make you live long and fight cancer.
The news that eating some foods can fight cancer is the most widely circulated, and the best among them are garlic and onion .
Garlic and onions are both "foreign household registrations". After being introduced to China, people gradually discovered that they have many wonderful uses. Moreover, with the in-depth analysis and research of pharmacology and , it was surprisingly found that garlic and onions contain a lot of anti-cancer and cancer-killing ingredients, which have good cancer-killing effects in animal tests.
The widely circulated news is that garlic and onion fight cancer through two ways:
One is to directly fight cancer, inhibit and eliminate cancer cells . For example, garlic is rich in organic sulfides such as allicin , alliin , etc., which has an inhibitory effect on prostate cancer , colorectal cancer, breast cancer , gastric cancer , etc.; onion contains more quercetin , which has a preventive effect on oral cancer and colorectal cancer.
One is indirectly affecting cancer . For example, garlic and onions contain selenium and prostaglandin A components, which prevent diabetes , cardiovascular and cerebrovascular diseases, anti-fatigue and aging, and indirectly play an anti-cancer effect.
In fact, anti-cancer such as garlic and onion should be "paper data", because the experimental data are obtained from animal cell tests, and it still has a long way to go before applying it to the human body, and it cannot guarantee that the human body can be used well. In addition, the dosage in animal tests is relatively large. To achieve the same dosage as in animal tests, at least 1 kg of garlic and 5 kg of onions should be consumed every day, and it is not operable for a long time.
The key is that even if garlic and onions are really "anti-cancer stars", the types of cancers they can deal with are limited. If you prevent these cancers, don't care about other cancers?
In a sentence: Animal tests to fight cancer effectively does not mean that the human body is effective; containing certain anti-cancer substances does not mean that it can really fight cancer; it is not realistic to fight cancer by relying solely on a certain type of food.
Cancer is formed after a long period of development after cancer cells mutate. The cancer cells are mutated from normal cells. Originally, normal cells divide and replicate once every few days, and will automatically apoptotic after dozens of consecutive times. However, cancer cells have changed these key settings, and their division speeds are accelerated, and they will not break themselves. They can also grow blood vessels and illegally connect to circulating blood vessels, plundering a large amount of nutrients. Therefore, after cancer cells mutate, they actually divide infinitely and develop pathologically, invading human organs and destroying healthy tissues.
Corresome parts of the human body have been repeatedly inflamed, damaged, and ulcerated for a long time, and errors occur during normal cell repair, which produces cancer cells. Or the more times normal cells divide , the more disorders you will be, and cancer cells will be produced. There is a positive proportional relationship between the frequent divisions and the production of cancer cells.The more cell divisions are, the older the cell age, the more likely it is to develop cancer.
However, after cancer cells appear, their growth will not be smooth. They must first be "checked" and "identified" by immune cells . Once the immune cells are strong and responsible enough, it is difficult for cancer cells to avoid them. On the other hand, if they are lazy and not powerful, cancer cells can survive, which becomes a hidden danger. Even if cancer cells grow into small tumors, once immunity regains the initiative, the cancer foci will still be firmly hit, and may even shrink and disappear.
Factors that affect immunity are the first, because as we age, organs and tissues gradually age and their functions decrease, and their immunity will naturally decrease.
Other factors include: suffering from immunodeficiency diseases, endocrine disorders, genetics, chronic disease interference, poor living habits, environmental impact, iatrogenic damage, natural or biological invasion of , etc.
Scientists have found that between cancer cells, cancer foci and immunity, many times, they are playing the "hide and seek" game. As long as the immunity is strong enough, the cancer cells will pretend to be extremely docile and low-key, and simply lie flat; once the immunity cannot be suppressed, the cancer cells will quickly become active, splitting, replicating, proliferating, and growing, and take a multi-pronged approach. As long as there is enough time, small cancer cells will become a big threat. Sometimes even if cancer cells grow into malignant tumors, if the immune system regains control, the cancer foci will obediently sleep.
Therefore, working hard to maintain and protect immunity and prevent frequent fluctuations and decline too quickly will create a reliable line of defense against cancer. As long as you do this for a long time, you will be guaranteed to prevent and fight cancer, which is also something that cancer is afraid of.
How to maintain and improve immunity?
First of all, you need to understand your immune system, what is composed of, how it works, what are the signals of decreased immunity, etc. For example, if you have frequent colds, good sleep, you will feel fatigue, your wounds are prone to infection, and your stomach is more delicate, etc., which means you lack immunity.
Secondly, through dietary adjustment, the dietary structure is diversified, away from spoiled and unclean foods, eat less high-salt, high-fat foods, stay away from foods that may be contaminated by parasites, and insist on eating on time.
Again, keep a healthy way, do aerobic exercise frequently, find exercise methods that suit your age and like, persist for a long time, and avoid wrong behaviors such as staying up late and overwork.
Also, pay attention to psychological adjustment, pay attention to relieving negative emotions such as anxiety, depression, irritability, anxiety, etc., and maintain a positive attitude.
Finally, learn to use modern medical power to insist on regular inspections, and receive preventive vaccines based on actual conditions, understand practical common sense of health care, etc.
