Unexcluded right hilar lymph node metastasis means that lymph node metastasis may have occurred in the right hilar side of the patient’s lungs in the examination report, but the diagnosis has not been confirmed directly. The term “not excluded” is commonly used in medicine, which can be simply interpreted as “not excluded” or “possible”. Right hilar lymph node metastasis generally refers to malignant tumor metastasis through the lymphatic channel to the right hilar lymph node, which can lead to hilar lymph node metastasis. Right hilar lymph node metastasis is a malignant tumor that has metastasized to the right hilar lymph node through the lymphatic channel, resulting in the growth of the same tumor in the hilar lymph node. The diagnosis of hilar lymph node metastasis is usually not confirmed without the exception of right hilar lymph node metastasis, in which case a biopsy of the localized tissue may be performed to determine whether malignant lesions have developed. If right hilar lymph node metastasis is diagnosed, the patient needs to actively cooperate with the doctor to remove the primary tumor, and can also cooperate with lymph node dissection, and give chemotherapy, radiotherapy and other comprehensive treatment to alleviate the disease and prolong the life.
