Genes that trigger cancer can be turned off before birth, according to research.
Genes that trigger cancer could be turned off – before people are even born, according to new research.
Scientists have found a tumour ‘switch’ that develops hours after fertilisation.
The discovery offers hope of a screening program, personalised vaccines – or even embryo engineering.
Co author Professor Tony Perry, of the University of Bath, said: “Our work could open a new clinical chapter for the early detection of cancer.”

In experiments on mice, the international team found gene activity in embryos kicks off within four hours of sperm injection.
These include ‘oncogenes’ which have the potential to cause cancer – if mutated.
The findings are expected to apply to humans.
Prof Perry said: “Many factors responsible for the dawn of gene activity in embryos have long been known to be major oncogenes.”
It is the first time a pre-set order of events has been established in one-cell embryos in any species.
