Suggest Treatment For A Small Lump On The Jaw

Back in late October I noticed a small, lump under my left jaw. I saw an ENT doctor about this who initially thought it was a swollen lymph node and tried antibiotics. After that did not help, he ordered a MRI of the neck. The results showed a well-circumscribed mass on the left submandibular salivary gland, about 1.4 cm. It does not hurt, no other symptoms and has not grown in size. t1 signal was diminished, while T2 was moderately increased. There was considerable contrast enhancement. No bulky lymphadenopathy, bony lesion or vascular lesion was seen. Radiologist recommended surgical incision or biopsy. After the MRi results my doctor also suggested the surgical removable of the entire gland after a FNA was done. I just had a FNA biopsy but the pathologist was unable to get a sample due to the small size of the tumor and the fact that it is movable. Should I talk to the doctor about surgical removable for biopsy? Does this seem more like a benign mass to you? Should I get a second opinion from another ENT?
