Lymph nodes can remain swollen even after symptoms have subsided for sometime, and are little cause for concern unless other symptoms are present ie: Night sweats
, rapid weight gain/loss, extreme fatigue
. These could be signs of lymphoma
. Some studies have shown that the Epstein Barr virus is linked to a higher risk of developing lymphoma, but not enough to be worried. If you were anxious about cancer, a CT scan can be used to determine the extent of lymphadenopathy
or it is also possible to have a biopsy done.
I hope this helped.
