My husband had a cancer in his salvia gland. You could see the knots right under his jaw line.The bio. showed infection. he went to ENT. DR. that had to be taken out with surgury,well it turned out cancer. HE went through 7 Wks. of radiation.And went right back to work, BUT has gone down hill since.WE have now retired.They say he does not have cancer now. BUT I think he thinks so.I hope you will go to ENT Dr.AND good luck.
