Rates of yearly lung cancer covering vary among United States Department of State , but the national norm suggests that only about 10 % of eligible masses get checked , Robert Smith , senior frailty Chief Executive for former cancer detecting science at the ACS and direct author of the guideline , tell The Washington Post . Screeninginvolves low - dose cypher tomography(low - dose CT ) , a scan that mix a serial publication of ten - rays into a detailed image of the inside of the body .

Now , the ACS recommends that current and former smokers ages 50 to 80 with a 20 pack - yr smoking account be screen annually , regardless of whether or when they throw in . These alteration mean that about 19.3 million masses in the U.S. should now be eligible for riddle , compared with 14.3 million under the late road map , NBC reported .
