Could lymphoma cause constipation, one swollen lymph node, low grade fever, severe fatigue and excessive sweating?

Diagnosis, symptoms: Symptoms alone can not be helpful to make a diagnosis of lymphoma, Physical examination to assess the size of the lymph node, tests to check the rest of the body and a biopsy of an enlarged lymph node, all put together, help us to make a diagnosis. You need to go to a doctor for examination if you are concerned about your symptoms(if these are progressively getting worse)
