What can cause enlarged occipital lymph nodes
The medical classification of lymph node conditions is divided according to the cause. They can be inflammatory or cancerous (neoplastic). The inflammatory type is then subdivided into that of a specific infection like tuberculosis or leprosy or the non-specific type -the most common cause of lymph node enlargement-, which results from a bacterial or viral infection that drained into the neighboring lymph nodes. The cancerous or neoplastic type is further subdivided into primary as leukemia or lymphoma or secondary when cancer affecting the area drained in this group of lymph nodes. The former scheme is studied in detail by doctors, but is less relevant for normal people because we can´t stress enough how common unspecific infections are and how uncommon diseases like leprosy are. Therefore, we will arrange the causes according to their likelihood.
