Blood test for lung cancer as 1st-line screen before LDCT
The use of low-dose CT as a screening tool for lung cancer has been criticized for its high cost and its feasibility, given the large number of long-time heavy smokers and ex-smokers and the complexity of the process. What if a less expensive and more easily administered test could refine who is at highest risk for lung cancer, and therefore identify the top candidates for low-dose CT?
