 [ Symptoms ] i am a 50 year smoker female 71 yrs old is a ct lung scan offered by well known cancer ctr for 100 worthwhile  i have tried quitting but anxiety disorder interfers [ Disease ] my short answer no mobile health scans are a recent fad for a fee some organization will take a whole body ct scan or some foolishness it is not beneficial for most people and it exposes you to a hefty dose of radiation in your case i think the question is are you considering doing this for fear of lung cancer if so consult your primary care physician a simple chest x ray is a good starting point for diagnosing lung cancer and lung cancer is not the only smoking related cancer bladder cancer colon cancer and mouth cancers all are high on the list of cancers smokers experience i do not say that to scare you but merely to point out that shelling out 100 for a chest ct scan is not necessarily a good option if you are concerned about smoking side effects let is just be realistic for a moment do you want to quit smoking at age 71 after 50 years of smoking it is ok to say no  you just need to understand you may be trading some life expectancy for your enjoyment of smoking if you are ok with that so be it on the other hand it is never too late to quit if you have no signs of any cancers in your body and you wish to possibly extend your life expectancy talk to your health care provider about all the new options to help you quit smoking two prescription medications in particular have good track records for helping people quit permanently there is no shame in using a stop smoking aid quitting cold turkey is the least successful method i wish you all the best
