Moveable painless lump in front of neck between my r ear and chin. no other symptoms. been there 5 plus years. should i be worried that its cancer?

Lymph node: If it has been there and is unchanged for 5 years, cancer is unlikely. That area would be common for a benign reactive lymph node. Also possible to have a lipoma or other benign cyst. Neck region could also be a thyroglossal duct cyst. The best way to find a definitive answer is to see an ENT physician for a possible needle biopsy.

No: Everybody has at least one palpable lymph node in the neck. What you're describing is a normal neck exam. Stop worrying and be thankful for good health.

Unlikely: to be cancerous if it has remained unchanged for 5 years. See your doctor to get it checked. Could be a cyst, node............
