Inguinal lymph node metastasis of anal canal cancer usually does not belong to advanced stage, and anal canal cancer metastasis to inguinal lymph node belongs to proximal lymph node metastasis, which is early stage tumor. If metastasis of anal canal cancer occurs, there are generally two aspects of metastasis, proximal localized metastasis and systemic metastasis, proximal localized lymph node metastasis does not belong to the advanced stage of cancer, and inguinal lymph node metastasis of anal canal cancer belongs to proximal lymph node metastasis, which does not belong to the advanced stage of cancer, and patients do not need to be overly worried about it, and there are many ways to diagnose the advanced stage of the cancer, which should not be based on the metastasis of lymph nodes only. If metastasis of anal canal cancer occurs, patients should go to the hospital in time for further diagnosis and treatment, keep a good attitude and actively cooperate with doctors for treatment, and do appropriate exercise to divert attention.
