Tumors of the External Ear
Tumors of the ear can be benign or malignant. They can occur on the external ear, or in the ear canal, the middle ear or inner ear. Tumors in different areas of the ear behave differently. Thus, it is necessary to describe tumors based on their site of occurrence, as well as their behavior and treatment.
Tumors of the External Ear Canal
The external ear canal begins at the opening of the cup-shaped portion (concha) of the ear and extends downward to the ear drum. Tumors that occur in the ear canal can be benign or malignant. Malignant tumors of the external ear canal are very serious. Immediate biopsy of any suspicious lesion in the external ear canal should be performed immediately.
Causes of Ear Cancer
The exact cause of ear cancer is not known. Individuals with history of chronic ear infections (>10 years) are at a higher risk for developing ear cancer.
