Dr Paul Townsend, of University of Southampton, said: "That would be fantastic, it would be faster, more certain and less invasive." Dr Paul Townsend, of University of Southampton, said: "Already we have seen significant bio-markers of breast cancer in the samples.
"The quality of the samples we have from Guernsey has been the key but it is early days."
