1) PHYSICAL Evaluation: – A physical examination will begin with a few pre-determined questions about your current health. They will ask you about any observeable symptoms you have been experiencing then. They will probably ask you about your smoking habits also. If the physician believes you may have NSCLC after the physical examination they will probably request that you participate in further lung cancer exams. 2) Upper body X-RAY: – If after the physical examination your doctor believes you might be at risk for NSCLC they may suggest an x-ray of your chest.Anna L. Zisman, M.D., and colleagues at Evanston-Northwestern Health care, Feinberg School of Medicine, Northwestern University, Evanston, Ill., examined the records of 161,172 patients with colorectal tumor to assess whether specific risk factors, alcohol and tobacco use, should also be considered in screening decisions. They analyzed the partnership between use of these chemicals and age of starting point of colon cancer in addition to location of onset–distal or proximal colon. Distal tumors, including those in the low left area of the colon and the rectum, can generally end up being detected by flexible sigmoidoscopy, while proximal tumors in the right aspect of the colon can be missed by strategies apart from colonoscopy.
