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.
While the decision on whether Medicare should cover lung cancer screening is still up in the air, a new study warns that such screening would increase costs. Adding low-dose CT (LDCT) to the Medicare program, which covers people older than 65 year, could result in the detection of approximately 54,900 more lung cancer cases during a 5-year period, with most at an early and more treatable stage.
