my son is 4 years old. he has had enlarged tonsils for a while now and they are being monitored. He has allergies which are also being monitored. However, on his last visit to the doctor there seemed to be concern as to one of the tonsils looking larger then before. The doctor said that he needed to see an ENT as there maybe 05% - 1% chance of a Lymphoma. I am concerned and very stressed about this. Please advise and guide me.
