A schwannoma is a type of tumor that arises from Schwann cells found in the nerve roots or peripheral nervous system. They typically grow slowly and are benign. Vestibular schwannomas, which develop in an inner ear nerve, are the most prevalent kind.
In addition to minimizing potential complications by treating the tumor while it is still small and before it causes significant damage or symptoms, early treatment of a schwannoma is essential because it allows for better preservation of function in the affected area, especially when the tumor is near vital nerves like those responsible for hearing and balance.
Causes
Most of the time, the cause of schwannomas is unknown. About 90% of cases happen infrequently, or at random.
Schwannomatosis, neurofibromatosis 2 (NF2), and Carney complex are examples of genetic illnesses that can result in schwannomas. According to genetic research, the NF2 gene on chromosome 22 is crucial for the formation of schwannoma.
Risk Factors
This procedure carries the risks of bleeding, infection, and anesthesia-related side effects. Additionally, there is a chance of nerve injury, which could result in paralysis, numbness, or weakening in the afflicted area. Under the supervision of a skilled neurosurgeon, these side effects are uncommon. You will have a detailed discussion with your neurosurgeon about these risks and the steps being taken to reduce them.
Unfortunately, there is no way to avoid schwannomas. Most of the time, they occur at random for unclear causes. Certain genetic factors that increase your risk of developing specific tumor types are linked to about 10% of instances.
Stereotactic Radio Therapy: To eradicate tumors, stereotactic radiosurgery (SRS) employs many laser beams that are carefully focused. To avoid potential difficulties, your doctor could suggest SRS rather than surgery if the tumor is close to important blood vessels or nerves.

Gamma Knife Radiosurgery: Brain stereotactic radiosurgery is another name for gamma knife radiosurgery. Since there is no incision made into the brain tissue, it is not surgery in the conventional sense. About 200 beams of focused radiation are directed straight at the vestibular schwannoma using specialized equipment. Because the radiation is precisely directed to the place where the rays converge, it has little influence on the other parts of the brain. The first-line treatment for tiny or medium-sized vestibular schwannomas is now Gamma Knife radiosurgery. According to one study, it is a safe and efficient therapeutic method that effectively cures vestibular schwannoma by stopping or shrinking the tumor in 97.1% of instances. Gamma knife radiosurgery is an outpatient procedure that can be done the same day, and most patients have either no side effects or very minor ones. Gamma Knife radiosurgery has two key advantages: it is almost painless, and the patient can resume their pre-treatment activities shortly after the procedure.

Here are some of the reasons for choosing India:
It is treatable, yes. Schwannoma are usually not malignant, but if left untreated, they can develop and become more problematic. Some schwannomas can be removed without causing any damage to the surrounding nerve tissue, but if your tumor is large or deeply implanted, more surgery might be necessary.
The nation's healthcare institutions offer top-notch treatment alternatives, guaranteeing successful outcomes for many patients. Depending on the location and size of the tumor, treatment for Schwannomas in India is thought to be effective, with surgical options like microsurgery and minimally invasive Gamma Knife radiosurgery, especially for smaller tumors, allowing for good tumor control and preservation of important functions like hearing. To get the best results, it's imperative to seek treatment at a medical center with experienced neurosurgeons.
Yes, many Indian hospitals offer the following for Schwannoma treatment:
Always consider the following factors when selecting Indian hospitals:
The evidence that is currently available indicates that the success rate for treating Schwannoma in India is high, especially for vestibular schwannomas treated with stereotactic radiosurgery (SRS). Studies have reported success rates ranging from 78.2% to 86.9%..
Depending on where the tumor is located, a doctor will probably perform a physical examination, order imaging tests like an MRI scan, and possibly perform a biopsy to confirm the diagnosis. If your child has a schwannoma, you should look for symptoms such as a painless or painful lump that grows slowly, numbness or tingling in a specific area, one-sided hearing loss, dizziness, facial weakness, or pain.
Depending on the tumor's location, size, and treatment, a patient may experience long-term effects from a schwannoma such as tinnitus (ear ringing), balance issues, facial weakness or numbness, persistent hearing loss, and occasionally even trouble swallowing or moving their eye. However, most schwannomas are benign and slow-growing, so if they are properly diagnosed and treated, they rarely have a significant impact on life expectancy.
Providing a supportive environment, managing symptoms with medication and therapies as directed by the doctor, closely monitoring the child's seizures, seeking specialized care such as physical, occupational, and speech therapy, and being ready for any necessary surgical procedures, such as a hemispherectomy, are all part of caring for a child with Rasmussen's Encephalitis. Always check with your child's medical team for the best course of action.
