Hi welcome to health care magic forum,
Gland in neck or inside of your throat ?? Inside of your throat may be tonsillar enlargement .
over neck are called lympahdenopathy.
Signs of tumour is growing in size or in number due course of time.
I would suggest to see an ENT specialist
and go for thorough exsmination.
You can request for a FNAC if it is on neck or may be excisional biopsy
You may undergo for a tonsillectomy
if it is asymmetrical tonsillar enlargement.
