Enlarged mediastinal lymph nodes may not necessarily be metastasis of rectal cancer, but may also be inflammation, lymphoma or other malignant tumors.
Mediastinal lymph node enlargement is a common clinical phenomenon, if the patient has a history of rectal cancer and has mediastinal lymph node enlargement, metastasis cannot be excluded.
PET-CT examination and tumor index examination can be performed to evaluate whether this lymph node enlargement is related to rectal cancer.
If the patient does not have a clear history of rectal cancer, other tests should be further performed to evaluate whether there are other causes.
If necessary, tissue can be taken for pathological biopsy through puncture surgery or other means to clarify the cause of the disease.
It is recommended to actively cooperate with the doctor to improve the relevant examination, identify the cause of the disease and treat it at an early stage.
