Schwannoma is a type of tumor that originates from Schwann cells, the cells that produce the protective myelin sheath around peripheral nerves. Schwannomas are typically benign, meaning they are not cancerous and do not spread to other parts of the body. However, they can cause symptoms by pressing on nearby nerves or tissues.
Symptoms[edit]
The symptoms of a schwannoma can vary depending on the location of the tumor. Common symptoms can include:
Causes[edit]
The exact cause of schwannomas is not known. However, they are often associated with a genetic disorder called Neurofibromatosis type 2 (NF2).
Diagnosis[edit]
Schwannomas are typically diagnosed through a combination of physical examination, medical history, and imaging tests such as MRI or CT scan. In some cases, a biopsy may be performed to confirm the diagnosis.
Treatment[edit]
The treatment for a schwannoma depends on the size and location of the tumor, as well as the patient's overall health. Treatment options can include:
Prognosis[edit]
The prognosis for a person with a schwannoma is generally good, as these tumors are typically benign and do not spread to other parts of the body. However, they can cause symptoms that can affect quality of life, and treatment can sometimes lead to complications.
