What causes children's leukemia? Researchers who analyzed from various research in the past 30 years announced

byColin Maynard

Child'sAcute lymphocytic leukemiaIs increasing in wealthy society, and its cause was suspected to be related to electromagnetic waves and chemical substances. Under such circumstances, from a large number of research results such as genetics, cell biology, immunology, epidemiology, etc. conducted in the past 30 years, childhood leukemia is classified as "gene mutation" and "infection experienced shortly after birth A study that states there is a cause for "disease" was announced.

Professor Mel Greaves reveals likely cause of childhood leukaemia - YouTube


Professor Mel Greaves belonging to the cancer research institution in London denied the association with electromagnetic waves and chemical substances as a cause of acute lymphocytic leukemia from research of himself and researchers in various fields in the world over the past 30 years Did.

Acute lymphocytic leukemia is increasing in wealthy societies and is increasing at a rate of 1% per year even in 2018. Professor Greaves says that leukemia is associated with "genetic mutation that occurs when present in the mother's womb" and "not being in contact with pathogenic bacteria in early childhood", and by combining these two factors, childhood immunodeficiency and leukemia It was shown that it was caused.


Professor Greaves focused particularly on what is called "late infectious disease theory", which means that the infection experienced shortly after birth is to train the immune system, while this infection Infectious diseases after growing without going through is to trigger acute lymphocytic leukemia. Professor Greaves thinks that not only leukemia but also type 1 diabetes, autoimmune diseases, allergy and so on can be prevented if the immune system is properly trained by the time the child is one year old.

The above conclusion is not derived by one study but one derived from matching multiple studies done in the past like a jigsaw puzzle. Professor Greaves says, "Studies strongly indicated that acute lymphocytic leukemia has biological causes and that various triggers act on" children whose immune system is not properly prepared " "I said.


The evidence underlying Professor Greaves's research includes the following.

· It happened in MilanSwine flu7 children became acute lymphocytic leukemia
· Children who went to daycare centers and children with upper brothers are exposed to microorganisms, so the probability of becoming acute lymphocytic leukemia is low
· Breastfeeding raises bacteria that are good in the stomach and intestines of children and protects children from acute lymphoblastic leukemia
· Vaginal birth has lower probability of acute lymphocytic leukemia than caesarean section with less contact with microorganisms
· Animals raised without contact with microorganisms cause leukemia when exposed to infection

However, the merit of microorganisms is complicated, and the results of this research do not insist on "being covered with mud" or "not too hygienic". Meanwhile, Professor Greaves stated that "Acute lymphoblastic leukemia that occurs in childhood is preventable". As further research is needed, according to Professor Greaves's view, giving children a safe food containing microorganisms, such as yogurt, may help to train the immune system.


We believe that the results of this research can be used for future medical care, but further research is needed. In the meantime, Professor Greaves thinks that "It is not too nervous to common infections, it is important to recommend social contact with people such as older children".

In the past, "fungus" was considered to be harmful in human life in many cases, but in recent years fungi have played an important role in understanding Parkinson's disease, depression etc. from allergy It is becoming clear that there is.
