The Darling River, 1,160 miles (1,879 km) in length, flows southwest from the edges of the Great Dividing Range into the Murray River. The Murray rises in the Australian Alps and flows 1,200 miles (1,930 km) to the Spencer Gulf, directly west of Adelaide.
In lung cancer screening, individuals who have a high risk of developing lung cancer but no signs or symptoms of the disease undergo low-dose computed tomography (LDCT) scanning of the chest.
If you are at risk, a CT scan can detect tiny spots on your lungs (called 'nodules') that may indicate lung cancer in this early stage (New England Journal of Medicine 2006; 355; 1763-1771).
