Neuroma

A noncancerous tumour of nerve tissue. In most cases, the cause is unknown; rarely, a neuroma develops as a result of damage to a nerve. A neuroma may affect any nerve in the body. Symptoms vary, but there is often intermittent pain and sometimes weakness and numbness in the areas that are supplied by the affected nerve. If symptoms are troublesome, the tumour may be surgically removed. (See also acoustic neuroma.)
