Hello. The attached CBC report is suggestive of a mild infection or inflammatory condition. WBC count is normal so its nothing to get worried about. A little higher lymphocyte percentage does not indicate cancer. An underlying infection may result in both a high lymphocyte count and high ESR. If she has no other symptoms of infection like fever and no other chronic inflammatory conditions like arthritis, the counts and ESR should normalize soon. If she has fever or any other symptoms, I would suggest consulting your physician for further evaluation. Thanks
