Lymphocytic infiltration is generally what is described in the pathology report. Many patients may mistakenly think that lymphocytic infiltration is cancer, but it is not necessarily so, for example, benign tumors may also have lymphocytic infiltration. Lymphocytic infiltration may occur in low-grade malignant tumors or other highly malignant tumors, which are often referred to as cancer, and should be analyzed more specifically in the context of the patient’s condition. It is possible for chronic inflammation, benign tumors or malignant tumors to have local infiltration due to the immune response of the body leading to an increase in lymphocytes. For example, if a benign tumor appears, surgery is not necessarily needed. You can review it regularly to see if there is any change, and if the lump grows larger, then consider surgery. If lymphocytic infiltration occurs in malignant tumors, it does not necessarily mean that the condition is deteriorating. If malignant tumors can be treated surgically, surgical radical treatment is also the main focus.
