Health Desk-- 23 May, 2018: A British scientist said our modern germ-free life is the cause of the most common type of cancer in children. Acute lymphoblastic leukaemia affects one in 2,000 children.
Prof Mel Greaves, from the Institute of Cancer Research, has amassed 30 years of evidence to show the immune system can become cancerous if it does not "see" enough bugs early in life.
It means it may be possible to prevent the disease.
The type of blood cancer is more common in advanced, affluent societies, suggesting something about our modern lives might be causing the disease.
There have been wild claims linking power cables, electromagnetic waves and chemicals to the cancer.
Studies showing children who went to nursery or had older siblings, which expose them to bacteria, had lower rates of leukaemia
