Initial findings from the Summit study has identified 180 cases of lung cancer among 12,100 smokers and those who have quit. Of those, 70% were at stage one and two. The Summit study, led by UCL London, plans to enrol 25,000 people aged between 55 and 77, who are at higher risk of lung and other cancers due to a significant smoking history. Its findings are due to be published in a medical journal later this year. |
