Pathologic report did not see cancer involvement at the margins, indicating that the surgical resection was effective, and this diagnostic method has a high degree of overall reliability. After surgical resection of malignant tumors, pathological examination is often needed to judge the effect of surgery. The absence of cancer involvement at the incision margin indicates that the cancer cells have not infiltrated into the neighboring tissues, which means that radical resection has been achieved and the prognosis is good. On the contrary, if there are cancer cells remaining, radical resection has not been achieved, and then postoperative adjuvant treatments, such as radiotherapy, chemotherapy, etc., or another surgical resection is needed to achieve a better therapeutic effect. Pathological examination has some errors, but generally speaking, it is basically accurate, and patients should actively cooperate with doctors for treatment.
