11 Critical Mouth Cancer Symptoms to Recognize Early

6. Nerve Changes

Nerves that provide feeling to an individual's tongue and lower lip can be affected when it comes to mouth cancer, and these effects can result in changes in feeling. Some patients experience numbness, while others notice a tingling that almost feels like pins and needles. For individuals who suffer from diabetic nerve damage, it is similar to those sensations, but instead, this change in feeling is felt within the mouth. When nerve damage occurs, earaches may also develop due to the fibers that connect the individual's tongue to the ear.
