Dear friend your cervical lymph node biopsy is typically tubercular picture. Once a node is in this state due to TB the reduction in size does not take place it has to be surgically removed and biopsied. If your other parameters namely ESR and CBC are within normal limits, and you have completed the full course of ATT you need not worry. Better still check with your treating physician if he/she has any other suggestion, chances of malignancy in this case are negligible
