Got diognosed with benign generalized lymphoadapthy. Doc said bc their soft and not growing their fine. But I'm scared. Is this true?

Can be. Sounds like you did the right thing by being evaluated. Many causes of lymphadenopathy exist, but generalized selling suggests a systemic problem. I am sure your physician explored viral illnesses like mono and CMV or lymphomas, tb, autoimmune processes, etc. Persistent generalized lymphadenopathy is a recognized condition in which the nodes have no apparent cause. Best to keep close follow-up tho.
