Dear sir My 1.5 years old daughter had developed enlarged lymph nodes in groin neck and arm pit area where both arm pit nodes are sizing 1.5 cm from last 2 months. Her mt test for tb was positive at 10 mm. Doctor prescribed akt and its 1.5 month some nodes size reduced but both arm pit nodes size is not reducing they are still 1.5cm. I recently went for biopsy but doctor told size is not big enough for biopsy. Are nodes with not reduction in size sign of limphoma??
