Tests to detect cancer up to three years before it occurs

Solange Peters, Head of Oncology at CHUV, reckons it may take several more years, but "sooner or later we'll be using this very advanced technology". For the time being, "these tests are not sensitive enough to allow us to use them". But the day this technique is proven effective, the expert pleads for everyone to have access to it, on the same footing as current screenings such as mammography, colonoscopy or chest CT.
