Clean homes cause cancer

RAISING kids in ultra-clean homes increases their risk of developing the most common form of childhood cancer, a major review found.

Failing to breastfeed, giving birth via C-section and cocooning babies away from other tots also make it more likely.

Acute lymphoblastic leukemia (ALL) is preventable if children’s immune systems are “primed” by their first birthday, experts said.

This can be done by exposing them to germs through breastfeeding, vaginal birth, or playing with dirty toys and other kids. The findings are published in the journal Nature Reviews Cancer.

Study leader professor Mel Greaves, who has studied the disease for 30 years, said: “Most cases of childhood leukemia are likely to be preventable.

“New parents should be less fussy about common infections and encourage social contact in the first year of life.”

“They should let their baby mix with as many children as possible — play with the same toys, touch each other. I’d also encourage breastfeeding.”

Kids can only develop the disease if they are born with a particular genetic mutation, which occurs randomly in one in 20 pregnancies.

But it is “triggered” when a child, who has not been exposed to bugs in the first year of their life, catches a viral infection, such as flu.

I’m not saying though, that some people aren’t way OTT with cleaning, I’d agree with that sentiment.

Delayed infection hypothesis
There is some evidence that a common infection, such as influenza, may indirectly promote emergence of ALL.[6][4] The delayed-infection hypothesis states that ALL results from an abnormal immune response to infection in a person with genetic risk factors. Delayed development of the immune system due to limited disease exposure may result in excessive production of lymphocytes and increased mutation rate during an illness. Several studies have identified lower rates of ALL among children with greater exposure to illness early in life. Very young children who attend daycare have lower rates of ALL. Evidence from many other studies looking at disease exposure and ALL is inconclusive.

I think some people are more susceptible to certain illnesses. Some people are always getting colds and I never do - though I get a headache and achey limbs for a day so I may get a “weak” version of it.

The point is that it's thought a delayed immune system because of lack of exposure to bugs, etc, can be a cause for the cancer.

Yes, I’m gathering that now, but my point is, I don’t think I buy it.
