If i have a lump on my neck, should i be worried about head and neck cancer?

Not always: A lump in the neck can be due to infection, fatty tumor, enlarged salivary gland, and sometimes due to cancer too. A lump which continues to grow in a high-risk person (male, smoker, alcohol user, tobacco chewing, poor oral hygiene/dentition) without any signs of infection should raise concerns.

It needs to be evalu: The lump could be carcinogenic or a lipoma-insignificant growth. Have your private M.D. Assess this.
