Schwannomas are tumors made up of nerve fibers. They are often found in the head and neck area, though they can be found anywhere. They are not usually cancerous but can cause weakness and pain. If they are cancerous, which is rare, they are usually called neurofibrosarcomas.
Causes of schwannomas
The causes of schwannomas are not clear, though some risk factors have been identified. Individuals between the ages of 30 and 60 years old seem to be at a higher risk for developing these tumors. There is also a genetic component. Individuals who have a family history of neurofibromatosis type 2 are at a higher risk.
Symptoms of schwannoma
Schwannomas on nerve cells closer to the body surface will probably be discovered sooner than the deeper ones. The deeper ones tend to be much larger when found. A symptom of this tumor is a mass that is growing. It can be painful, but often is not. Another indication that this mass may be a schwannoma is that there is usually an electric-like shock when the area of the schwannoma is touched.
Diagnosis
It is important to get an accurate diagnosis because other more serious diagnoses can have similar symptoms. Your physician will probably use X-rays, MRIs or ultrasound to explore the tumor site. The doctor might take a biopsy.
Treatment
The treatment of schwannomas usually involves surgical removal. If it comes back after surgery, it is most likely because of incomplete excision and not a fresh occurrence of the tumor.
Warning
The idea of a tumor can produce much anxiety. Remember that schwannomas are easily treated and curable. It is vital to see a physician immediately upon discovering any mass in order to rule out the more serious issues.
