This is a disease which mostly goes undetected & underdiagnosed. The patient may come to know about enlarged lymph nodes only during physical examination for some other complaints. In this condition the abnormal overgrowth of cells of the lymph system that is similar to lymphomas is seen, this is why the disease is also called as lymphoproliferative disorders. It is not a cancer but is mostly confused with cancer because of overgrowth of lymph tissues. The treatment mainly deals with surgical removal of lymph node or immunotherapy.
