Schnoz pick to diag-nose lung cancer; hEALTh.
Scientists have found that genetic changes in the lining of your hooter are linked with early onset of disease.
The discovery could lead to the first safe test for lung cancer in smokers.
Dr Christina Anderlind said: "The current tests are highly invasive, such as open lung biopsy. But the nose could be used to diagnose it in the early stages, when there is a greater chance of long-term survival.
"At an early stage, the fiveyear survival rate is 60% but only 2% at a late stage."
Her team, from America's Boston University Medical Center, collected cells from the noses of 33 smokers already being tested for lung cancer. They found 170 differences between the genes in those who had it and those who did not.
She added: "it would make early diagnosis of lung cancer more feasible."
