"Acute lymphoblastic leukaemia is caused by a sequence of biological events. The initial trigger is a genetic mutation that occurs in about one in 20 children.

“That mutation is caused by some kind of accident in the womb. It is not inherited, but leaves a child at risk of getting leukaemia in later life,” adds Greaves.

For full leukaemia to occur, another biological event must take place and this involves the immune system. “For an immune system to work properly, it needs to be confronted by an infection in the first year of life,” says Greaves. Without that confrontation with an infection, the system is left unprimed and will not work properly.”

And this issue is becoming an increasingly worrying problem. Parents, for laudable reasons, are raising children in homes where antiseptic wipes, antibacterial soaps and disinfected floorwashes are the norm. Dirt is banished for the good of the household."
