Treatment for Brain Tumor
Surgery
Most of the brain tumors will need surgery and most of the surgeries related to brain and skull base will be done by microscope or endoscope. So microscopic surgical resection of brain tumors will maximize the safety and lead to as much as possible safe resection of brain tumors leading to minimal to no neurological deficit.
Similarly brain tumors like pituitary and other skull base tumors will be removed with the help of endoscope through nasal route with no to minimal scar if needed.
Tumor Embolization
Some tumors of brain like meningioma and other vascular tumors like juvenile neuro-angiofibroma may need pre-operative tumor embolization to reduce blood loss during surgery leading to safe total removal.
Radiotherapy
Radiation therapy (also called x-ray therapy, or irradiation) is the use of one type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated by damaging their genetic material, making it impossible to grow and divide. Although radiation damages normal and cancer cells, most normal cells can recover from the effects of radiation and function properly.
Chemotherapy
Chemotherapy is to administer drugs that destroy tumor cells. It is sometimes the only treatment option, especially when the tumor is inoperable. It can be used alone or in combination with radiation therapy, before or after the operation. Before the operation, it reduces tumor volume to facilitate the surgical procedure. After the operation, It helps to destroy the remaining cancer cells.
