Question
A tumor has grown on my shoulder and it has been gradually increasing in size. After a medical examination, it was diagnosed as a ganglioneuroma and has undergone surgical treatment. However, recently, a similar tumor has been growing on my head, and my family is worried. What are the causes of ganglioneuroma?
Answer
Ganglioneuroma is a benign tumor that occurs in the ganglion, typically located near the sympathetic trunk, and sometimes may also appear in internal organs. The cause is not yet determined. If the tumor is completely removed surgically, no further treatment is usually required. If the removal is not thorough, postoperative radiation therapy may be necessary. In cases of recurrence after surgery, it is usually related to the thoroughness of the surgical removal and whether there are other multifocal tumors. It is recommended to undergo further examination at a hospital.
