I'm currently having investigations for Lymphoma as I have a swollen lymph node near my right collarbone.

I have had a chest xray and blood test. The xray results are not back yet, but my blood test results are ''borderline''. I had to ring to check if they were back though, and the receptionist at the doctors said if they had detected anything really abnormal they would have rang me. 

I'm still having further tests at the hospital on the swollen lymph node, but not until next week.. should I be worried about the borderline blood test result?
