Dr. Xu Xixian, a colorectal surgeon at Mackay Memorial Hospital, said that regular and accurate follow-up is very important, and for patients, every follow-up visit is actually a hidden pressure, and they are afraid that if they do not pass the test value, they will be sentenced by doctors to return to the long road of fighting cancer again. Xu Xixian said that clinically it has been observed that about fifty percent of patients diagnosed with colorectal cancer have not increased the CEA index, indicating that the traditional CEA value detection can no longer be applied to the prevention of active treatment before the occurrence of lesions, at this time, patients can be advised to use DR-70 with high sensitivity for detection at their own expense, which can assist traditional CEA tumor markers, and can effectively detect more than 7 percent of patients with normal CEA colorectal cancer who may recur, and obtain more accurate values and judgments.
