Australian researchers identify early blood marker indicating lung cancer risk

Scientists in Australia have reported a breakthrough in lung cancer detection. The study identified a specific blood marker associated with increased risk. Researchers measured the marker in participants to assess early signs. Findings suggest the marker appears before clinical symptoms develop. Early identification could enable earlier intervention and treatment. The discovery may improve screening strategies for high‑risk groups. Authors call for further validation in larger population studies. The work adds to global efforts to reduce lung cancer mortality.
