My father had parotid gland surgery (removal of tumor ) in 2008. They removed gland and a lymph node that also had cancer cells. He followed with radiation treatment. Recently , he has noticed an enlarged lymnp node below his ear on this same side. What tests should be performed? does this mean that his cancer has reoccurred?
Hi, welcome to Chat Doctor I am Chat Doctor.  You first have to do a FNAC from lymph node which will indicate what is the problem.
