Brain Tumors can be diagnosed by several imaging tests such as CT scan, PET scan and MRI scan to get clear images of the brain. A Biopsy is essential to confirm the type of tumor and to identify whether it is cancerous or not. A small hole is made in the skull from which tissue is removed and examined under the microscope. A neurological exam which assesses vision, hearing, balance, coordination, touch and reflexes helps to diagnose tumors in the brain and to detect which part is affected.
Brain Tumor Surgery primarily depends on the size, type and location of the tumor. This is an effective method for the complete removal of primary tumors, however, may not be as effective in case of secondary tumors which have metastasized to several parts of the body. Brain Tumor Surgery has to be performed along with other treatments such as Chemotherapy and Radiation therapy in order to kill all cancerous cells in specific locations.
In case of the tumor being deep inside the brain, only debulking is possible rather than complete removal. Debulking reduces the size of the tumor. The success of the treatment depends of the grade, size and stage of the tumor as well as the lifestyle of the patient.
There are several risks involved in Brain Tumor Surgery. There might be bleeding in the brain post-surgery or blood clots may form. Swelling in the brain may occur which can further lead to more complications. There are possibilities that the patient might be in coma due to unsuccessful treatment. There are also chances of undergoing seizures, convulsions, stroke during surgery or having an impaired speech, vision, poor coordination after the surgery.
