I was told a few times by Drs that if a small mass that size moves it usually isn't cancer. They might biopsy it to be sure. I have had 4 of those removed from my neck and shoulders. Biopsied confirmed what the Dr had said. Negative but he did remove them.

Since posting this. UPMC, Pittsburgh, Oct 2011 until Jan. I averaged about 2 to 3 surgeries a week there. w Can't have jaw made as bone is deteroriating steaily that is left in jaw. Mersa is to blame. Feeding tube . Had trach for 4mos. Got it out April.
