Radiation Therapy Gives an Effective Treatment to Brain Tumor

A brain tumor shows the abnormal growth of cells and within the brain. This condition can be cancerous (malignant) or non-cancerous (benign). These tumors have the capacity to destroy healthy brain cells by covering other parts of the brain. Generally, they cause inflammation, brain swelling and pressure within the skull. There are mainly two categories of the brain tumors such as primary and metastatic. Though, a patient can go through several therapies but the brain radiation therapy is proving to be the most effective treatment for this disease.

 Some other treatment options include surgery, chemotherapy and targeted biological agents. One can also go for a combination of these methods. Since the several therapies are available, the appropriate treatment depends on the size and type of the brain tumor. Surgical resection is probably the first treatment that can reduce the pressure in the brain. The brain radiation therapy targets the brain tumor while protecting nearby healthy tissues. Conventional radiation therapy applies external beams of x-ray, gamma rays, or protons that aim at the tumor to kill cancer cells and try to shrink brain tumor. These treatments involve brachytherapy, intensity-modulated radiation therapy and radiosurgery-IMRT.      

IMRT is an advanced and high-precision radiotherapy that uses computed-controlled x-ray accelerators to provide precise radiation to malignant areas within tumor. The radiation dose is designed to conform to the 3-D shape of the tumor by modulating the intensity of the radiation beam. Several meningiomas can be removed successfully by surgery. And in the complex cases, stereotactic radiosurgery, gamma knife and cyberknife are the viable options
