11 Critical Mouth Cancer Symptoms to Recognize Early

4. A Lump in the Neck

A lump developing in an individual's neck could indicate an enlarged lymph node., which is a common warning sign in both mouth and oropharyngeal cancers. If the lump is red, hot, or painful, it could mean an infection has developed and it is probably not cancerous. The same is true for lumps that come and go. When a lump is cancerous, it generally forms and grows slowly. Some individuals also experience a lump on their lip, in their mouth, or throat.
