DNA test can detect 18 early stage cancers, scientists say

US biotech firm designs cheaper, less invasive multi-cancer screening test it says could be ‘gamechanger’

Scientists have developed a simple DNA test that can identify 18 early-stage cancers that experts say could represent a medical “gamechanger”.

Cancer accounts for one in every six deaths worldwide, but early detection can significantly improve outcomes. Existing screening tests have drawbacks, including invasiveness, cost and low levels of accuracy for early stage disease.
