Mother-to-baby cancer link proven BBC WORLD NEWS 13TH OCTOBER 2009 In rare cases, unborn babies can be at risk if mothers have cancer New scientific research has proved that it is possible for cancer cells to be passed from a pregnant woman to her unborn child. This is the first time scientists say they have proved beyond doubt that the cells can be transmitted in this way. The case they looked at was in Japan, where they found that leukaemic cells were passed from a woman to her unborn daughter. Dr Frederick van Delft is a member of the research team from the British Institute for Cancer Research. He said cases like this were ''very rare''. Dr van Delft said the placenta and the child's immune system were supposed to be able to prevent the cancer cells from being passed on but they occasionally failed. Speaking to Newshour, he emphasised that this was the first time they were able to show genetically that this had happened. BBC WORLD NEWS 13TH OCTOBER 2009
