Hi, this is my first time on this site but find that your neck lump is similar to what I had 5 yrs ago. I found a lump under my left ear lymph node as well as one in the lymph node gap between my left shoulder clavicle. I waited 1 month to see if the lymph node would decrease in size but it didn't. I then realized it was time for a medical exam/opinion. I went to a UW Madison, WI physician and was given 2 options wait and see if it goes away OR go with a needle biopsy. I figured to have it tested sooner than later would be in my best interest. Results were suspicious and removal, if necessary, would be determined when I was on the table. Bottomline, I was squamous cell HPV p16 Pos. The surgeon determined the cancer stayed within the nodes but still removed an additonal 31 lymph nodes. Further, they could not identify the primary site but believed it was under the lower base of my tongue. That being said, my point is do whatever you have to do get a confirmed diagnosis for the enlarged lumps. Second, go to a Mayo Clinic or UWMC Madison, WI where they have the expert doctors that ONLY deal with these type of issues. Please believe me when I say, time can be your best friend OR worst enemy. I hope you the very best and God Bless!
