From a medical point of view, can formaldehyde cause an adult leukemia patient to die within two months?

As a doctor, we should start with medical students! I remember when I was studying anatomy, those bodies were soaked in formalin and smoked all the time! What is formalin? It's just a high concentration of formaldehyde. It's no use wearing a two-layer mask. I will always cry when my eyes are slightly closed! Autopsy is performed 2-3 times a week in our anatomy class, and freshmen study 1 year. There is no data showing that the leukemia rate of medical students is higher than that of ordinary people!

Therefore, whether formaldehyde causes cancer remains to be further confirmed, but it is indeed harmful to the human body!

Many decoration companies hype and exaggerate the toxicity of formaldehyde, which is actually a kind of commercial deception!

First of all, formaldehyde is harmful to human body, which is well-founded. The World Health Organization listed formaldehyde as a carcinogen in 20 12 (there is sufficient evidence to cause cancer to human body).

However, due to individual differences, no one can prove whether formaldehyde can cause enough carcinogenic harm to specific people within two months. It really varies from person to person. Just like some people have a bad stomach, they have diarrhea when they eat unclean things, and some people have nothing to do when they eat seaweed. The influence of individual differences is enormous.

Second, the harm of formaldehyde to human body is cancer, which not only causes leukemia, but also any other tumor. It's just that blood needs to be regenerated constantly, and it may be "injured", so many news reports live in a house with excessive formaldehyde for a while, and then leukemia or something.

Third, even if you really have a tumor, there is no conclusive evidence that it is caused by excessive formaldehyde. Can only say that it is highly correlated. Because even if you don't contact formaldehyde at all, you may get leukemia. Unlike AIDS, people who are not exposed to this disease will never get it again.

Finally, talk about decoration and formaldehyde. My daughter-in-law unit has recently moved, and it is also a newly renovated office. Although we promised to use environmentally friendly materials, we also put green plants and activated carbon, and bought a purifier from in addition to formaldehyde, it still smells bad and is not very comfortable.

This is something that can't be helped. If it is a house decorated by yourself, as long as it is not particularly anxious, it must be ventilated for more than 3 months to reduce the harm.

Theoretically, if it is the butterfly effect, formaldehyde may lead to the death of an adult leukemia patient within 2 months, but this is only the appearance, that is to say, in fact, it is not entirely appropriate to link formaldehyde with the death of a leukemia patient.

Because formaldehyde causes leukemia, it is uncertain in itself, and the cause of leukemia is unknown. Formaldehyde is the fuse of leukemia at most, but if there is no explosive, the fuse will be useless no matter how long it is.

So you can know that the function of formaldehyde is to add fuel to the fire of leukemia patients, which is possible. And it is possible that the acute development of leukemia will lead to the death of the patient for 2 months.

Therefore, on the surface, the above topic can be that formaldehyde seems to cause leukemia death, but in fact it is not caused by formaldehyde, but by leukemia. Formaldehyde does not play a very good role, but how much does it have to do with formaldehyde? If there is no formaldehyde, there are other analogues that can cause leukemia.

So formaldehyde may just be unlucky to catch up. If there is no formaldehyde, patients will also get leukemia, which is a matter of time. This is because leukemia is related to the patient's own factors, so is the so-called "tumor constitution".

First, insisting on the theory of formaldehyde harm is a copy written by in addition to formaldehyde Company. Of course, they did not say that the formaldehyde volatilization of decoration materials takes more than ten years and cannot be removed. Second, other benzene substances in the decoration are more carcinogenic, but volatilize quickly. Third, paint is harmful, but qualified paint is obviously less harmful, and it can seal other harmful substances to prevent volatilization, or limit the air concentration of harmful substances in unit time. Fourth, doctors are the people who have the most exposure to formaldehyde. One year's exposure to formaldehyde in human anatomy class is the amount that decoration workers have been exposed to for a lifetime. Needless to say, the anatomy professor has to be with formaldehyde all his life. This is like saying that X-rays are harmful, and interventional doctors are more acceptable than ordinary people all their lives. The final conclusion is that the new decoration has been ventilated for more than three months, and there is no need to ask for IQ tax except formaldehyde.

Doctors who specialize in leukemia tell you that if you don't pay attention, it is possible that formaldehyde will bring an adult from health to death within two months. In our daily life, we will encounter formaldehyde everywhere, especially in new houses.

It can be said that formaldehyde is basically around it. A little carelessness will affect your health. Today, I will talk about the harm of formaldehyde and how the leukemia patients I met discovered and finally left this human story very painfully.

The patient is a 48-year-old male. It can be said that he is in a strong age and his career has been very successful. It can be said that both career and family have a good harvest, especially having a son and a daughter under the knee. According to the medical history, due to the large number of family members,

They all spent a lot of money and bought villas from the urban area, which were luxuriously decorated. He also said in his statement that the best materials were used in the decoration, all of which were environmentally friendly materials, because he knew how harmful formaldehyde was to the human body.

So I was vacant for three months after the renovation, and specially invited a company that removed formaldehyde to carry out professional testing, and the test results met the standards. But why do you feel uncomfortable after living for two months? Here, we need specific analysis.

First of all, formaldehyde is a factor that induces leukemia. It can be said that it is everywhere. Even in ancient houses, formaldehyde actually exists, but this trace amount of formaldehyde will not cause harm to the human body at all.

So why is formaldehyde everywhere in the family? You should know that any colored furniture and electrical appliances that need to be fixed or decorated at home need certain auxiliary materials, such as glue, paint and various fabric products, such as curtain cloth, sofa cloth and sheets. , are treated with a large number of chemical reagents. It can be said that these things contain a lot of formaldehyde.

These formaldehyde will not accumulate in an open and ventilated environment, but we think that if it is in a closed and narrow room, it can be said that it is very fatal to the human body.

In a group of experiments in western science, if formaldehyde completely exceeds the standard, it can be said to be 10 times of the normal value. But in a square with good air circulation, generally speaking, it does not do much harm to the human body. After all, the accelerated air circulation dilutes the harmful toxins of formaldehyde.

In another set of data, even in a closed space, the formaldehyde content is less than one-third of the normal value. If people stay in this closed environment for 1-3 hours, you may feel dizzy, stuffy in the chest and disgusting. Therefore, we must analyze the harm of formaldehyde in a specific objective environment.

The patient just thought that the formaldehyde in his home was up to standard and moved in. It happened to be winter at that time, so basically the windows were closed all day. At night, when he slept, the windows were closed and the air conditioner was on, as you can imagine.

When the temperature is high, formaldehyde will evaporate faster, but your room is closed, and patients actually inhale a lot of formaldehyde during deep sleep. Over time, if you stay in a closed environment for a few days, you will feel uncomfortable and get sick soon.

For this patient, it only took 70 days from discovery to treatment to death. Because the patient is diagnosed with acute lymphoblastic leukemia and the type is high-risk, it should be arranged immediately according to the general process, that is, transplantation. It can be said that the transplant must have a matching bone marrow.

So in the process of waiting, the patient's condition began to break out, and we tried our best to save him, but in the end, he left this world with pain. It can be said that transplantation is the best way for leukemia patients at present, but transplantation is not necessarily suitable for everyone, and some are left on the waiting road.

It can be said that once leukemia is high-risk and high-risk, it will lead to a series of complications. When the autoimmune is reduced, people will quickly lose their "combat effectiveness". Finally, the virus swallowed himself.

You could say that. Once the elderly suffer from leukemia, their basic life will come to an end. My other patient, also a leukemia patient, should be living in a new house with my son.

Followed by a series of fever. When I went to the hospital, it was also M3 leukemia. Because the elderly themselves have some basic diseases,

At this age, there is no treatment, only conservative treatment. However, due to the decline of their own resistance or immunity, they cannot resist. Due to the side effects of the drug, the virus began to counterattack, and after more than 1 month of treatment, it finally died.

In fact, our understanding of formaldehyde in Du Yu is still very superficial. Formaldehyde itself is harmful, especially to children, the infirm and the elderly. Don't say that you are sick or even dead within two months. In fact, some serious patients will lose their lives within one month.

Especially in summer, when the temperature is high, formaldehyde is easy to volatilize. Be sure to keep indoor air circulation, regularly check the formaldehyde in your place of residence, and at the same time have a physical examination of yourself, especially in your new house. We must pay special attention to the influence.

In the 1970s, a dozen of us, afraid of paint corruption, deliberately looked for formaldehyde to prevent corrosion. At that time, there was no saying that formaldehyde caused cancer. Everyone has five or six bottles dripping with formaldehyde paint in front of them, and there is no cover. It can be said that the room is full of formaldehyde. This situation lasted for five years, and now it is almost 50 years. All the people involved are over 70 years old. No one alive or dead has leukemia or cancer. So don't be like leukemia when you see formaldehyde. It has something to do with personal physique. Everyone will produce a small amount of formaldehyde, so don't be afraid of everything.

It is not impossible for two months to cause cancer. Judging from people's physical quality and the time spent in the room, it is true that my husband's brother spent a lot of money on the newly bought house a few years ago. After living there for a long time, the whole person began to break his mouth and fester. He went to the hospital for a blood test and the result was leukemia. After 40 days in hospital, the unit reported 400,000. People are gone before they are 30 years old.

Leukemia, also known as hematologic cancer, is the cause of the heroine's death in Jacky Cheung's Far Away She. When Jacky Cheung sang this song, his strong feelings were heartbreaking.

1. What are the hazards of formaldehyde? Does it really cause cancer?

Looking through the literature, we know that formaldehyde is not generally harmful. When rats are exposed to formaldehyde, we find that:

Poisoning symptoms such as loose hair and listlessness appeared in mice. The poisoning symptoms of mice exposed to benzaldehyde combined with inhalation appeared earlier, and the poisoning symptoms persisted after stopping exposure.

Histopathological examination showed that some mice in the exposed group had pathological changes in lung, liver and spleen. The lung showed edema, congestion, inflammation and abscess, the liver showed edema, congestion and focal lesions, and the spleen showed giant cell infiltration.

The above results show that formaldehyde can do harm to the health of mice and cause lung and liver diseases. Irreversible damage to chromosomes and DNA can lead to abnormal differentiation of hematopoietic stem cells and pathological hematopoiesis, and there is the possibility of malignant clonal diseases in the blood system, that is, the possibility of cancer.

The final conclusion of this paper is that decoration pollution exposure may be one of the environmental risk factors of adult acute leukemia. The relative risk of acute leukemia staying within 3 months after renovation is 1.562 times of that staying more than 3 months after renovation, and the risk is 23.68%.

Second, how much formaldehyde can cause cancer?

It is unscientific to talk about cancer risk regardless of dose. The carcinogenic effect of formaldehyde is closely related to its concentration. Only high concentration formaldehyde pollution (1.0mg/m3) can cause cell mutation and cancer (including leukemia).

If the concentration of formaldehyde in indoor air does not exceed this level, it will generally not cause leukemia.

After reading this kind of question, I feel very heavy and can't spit it out!

Don't blindly participate in things that you don't pretend to understand or experience. If you think formaldehyde is harmless to the human body, then when you decorate your home, it is good to use more cheap materials, so as not to harm others and yourself!

I'm not an expert either, but I'm a practitioner in related industries, and I've seen many cases, and there are many online, so I can find them myself!

There are too many experts in China. What they say today and tomorrow is actually to safeguard the interests of relevant parties, not to safeguard the interests of ordinary working people at all!

Can we listen to them?

Then you don't believe what they say. Who do you believe?

Quite simply, doctors are most concerned about health because they have read too many stories. You just need to go to the hematology department to investigate and know that most children with leukemia have been decorating their houses at home recently. This may not mean anything, but are you willing to bet on the health of their families?

In fact, exposure to formaldehyde really does not necessarily cause cancer. After all, so many people are exposed to formaldehyde, and only a few people get cancer. But have you ever thought? Why are those people okay?

Adults, people with strong resistance and immunity, relatively speaking, if they are not in a closed space with excessive formaldehyde for a long time, there is basically no problem!

However, there is a process from quantitative change to qualitative change. At first, it only leads to decreased immunity, and then gradually affects health. What if I meet someone with low immunity before? Isn't it a direct question?

In short, the ventilation is basically no problem! No ventilation, good health, but also a small problem!

If there is no ventilation environment, coupled with serious formaldehyde exceeding the standard, and people's immune function is low, then there is definitely a problem, just a matter of size!

Don't take any chances, otherwise, you will regret it!

More formaldehyde questions, trust me privately and answer them one by one!

What is formaldehyde?

Formaldehyde, chemical formula HCHO or CH? O, the molecular formula is 30.03, also known as ant aldehyde. Colorless gas, irritating smell, irritating to people's eyes, nose, etc. The relative density of gas is 1.067 (air = 1), and the density of liquid is 0.8 15g/cm? (-20 )。 Melting point -92, boiling point-19.5. Soluble in water and ethanol. The highest concentration of aqueous solution can reach 55%, usually 40%. It is called formaldehyde water, commonly known as formalin, which is a colorless liquid with an irritating smell.

Formaldehyde is widely used as raw materials of phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pentaerythritol and dyes, and is widely used in furniture, wood-based panels, textiles, resins, glues, adhesives, antiseptic solutions, paints and other products. Formaldehyde has good adhesion and is widely used in the formulation of adhesives, glues and resins. There is a saying in the industry that there is no formaldehyde and no glue. Formaldehyde has a good antiseptic effect. Soaking wood with formaldehyde water is to prevent wood furniture from deformation, mildew and moth-eaten. In addition, textiles, especially pure cotton products, are easy to wrinkle, and textiles containing formaldehyde additives have better hardness and are not easy to wrinkle, so the formaldehyde content in textiles is high.

What is the harm of formaldehyde?

A. Irritation hazard: The main hazard of formaldehyde is irritation to skin and mucosa. Formaldehyde is a toxic substance in protoplasm, which has a serious stimulating effect on respiratory tract and eyes, and can cause edema and headache.

B sensitization hazard: direct contact with formaldehyde can cause allergic dermatitis, pigmentation and necrosis, and inhalation of high concentration formaldehyde can induce bronchial asthma.

C. Mutagenesis and canceration: High concentration of formaldehyde is also a genotoxic substance, which can cause harm to respiratory system, nervous system, blood system, digestive system, skin system and urinary system, and can cause lung cancer, nasopharyngeal tumor, digestive tract canceration, leukemia, bladder cancer and skin cancer. According to statistics, 90% of childhood leukemia comes from excessive formaldehyde in decoration.

D. Symptoms: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, upper gastrointestinal pain, palpitation, insomnia, weight loss, memory loss, autonomic nervous disorder; Long-term inhalation by pregnant women may lead to fetal malformation or even death, while long-term inhalation by men may lead to male sperm malformation or even death.

Where is the main source of formaldehyde in newly-installed houses?

Formaldehyde in homes and offices mainly comes from wooden furniture, carpets, sofas, wallpapers, wooden floors, cabinets, curtains, office desks and chairs, paints and coatings. Because these products need to be widely used in the production process.
