Thanks for using Healthcaremagic,
You have a Thyroid nodule
and your thyroid functions are normal, further treatment depends on the result of biopsy
as benign(Non cancerous) and Cancerous nodule have different treatment and surgical options.
Apart from T3,T4 and TSH,Thyroid scan to see hot spot, FNAC(Fine needle aspiration cytology) can be useful.
Treatment option include if benign watchful waiting,Surgery to remove nodule and biopsy.

Please get Biopsy and consult Endocrinologist
