Went To ENT Today. He Put The Tube Down Nose

Went to ENT today. He put the tube down nose into throat. The right side that I complained that something was there was fine. He said there is lymph tissue on left side though. He said he wanted me to return in 3 months to repeat the test but said he wouldnt be concerned about it if I wasnt a non-Hodgkins lymphoma patient in 2002. But he said he was just being over cautious because of my history. So is there just some tissue hanging there?
