My son was 3 years old when I discovered a lump in his neck. They sent us to an Ear, nose, and throat specialist and she suggested a biopsy to rule out cancer. It was so scarey, but I knew that they needed to rule it out. She and I discussed the fact that if it was cancer and I didn't do anything, it could be worse down the line. I put EMLA cream over the site 30 minutes before the test (numbs the top of the skin) and held him down. That was 15 years ago..the test was negative; he tends to be a "stuffy nose kid" with some seasonal allergies. Best of luck!
