Circulating Tumor DNA Early Indicator of Cancer
A blood test that identifies cancer and helps track progression is showing promise as an early warning sign, say researchers. The so-called liquid biopsy works by detecting circulating tumor DNA. "The most significant advance is that it can give us an indication that cancer is there up to 5 months before it even shows up on a tissue biopsy," said Sarah-Jane Dawson, MD, from the Molecular Biomarkers and Translational Genomics Laboratory at the Peter MacCallum Cancer Centre in Melbourne, Australia.

Children's Diets 'Far Too Salty'
Children in the UK are eating far too much salt, with much of it coming from breads and cereals, research suggests.

Breads and cereals accounted for more than one-third of the salt in children's diets. A fifth came from meat and one-tenth from dairy products. This was despite a UK-wide drive to cut salt levels in food. Continue Reading

She said she believed "research will find sugar is addictive", and that "we may need to introduce a sugar tax". The food industry said it was working on reducing sugar in products.
