Liang Jintong said that a patient was admitted clinically, and after surgery to remove the tumor, CEA was used to follow-up, but the CEA value was always high, which made the patient and his family feel very worried, and they were afraid of falling into the war against cancer again. Fortunately, after using the DR-70 cancer risk assessment index, the test values were normal, indicating that the high CEA may be due to the false positives caused by the patient’s smoking. Later, the results of patient follow-up showed no signs of recurrence, which made the patient and his family relieved.
