Hi welcome to heathcaremagic I have gone through your query and understand your concern Lymphadenitis is inflammation of the lymph nodes & is not a cancer. It arises as a result of the entry with the lymph into the lymph nodes of pathogenic microorganisms and their toxins, products of tissue decomposition, or tiny foreign bodies. The condition can arise from infected wound, furuncle, ulcer, dental caries and generalized infectious diseases and is manifested by enlargement and tenderness of the lymph nodes. Chronic lymphadenitis is characterized by enlargement, induration, and decreased mobility of the lymph nodes. Chronic nonspecific lymphadenitis develops under the influence of mild infection. Chronic lymphadenitis can also develop in connection with tuberculosis, syphilis, or other chronic infections. Lymphadenitis is treated by eliminating the condition’s primary inflammatory focus or cause and by physical therapy, antibiotics, and novocaine blockade. Some cases may require surgery. Hoping your query is solved Get well soon.
