Comprehensive Brain Tumor Center


The Brown University Comprehensive Brain Tumor Center at Rhode Island Hospital consists of expert neurosurgeons and oncologists collaborating to provide top quality multidisciplinary care of benign and malignant brain tumors. Our team specializes in the diagnosis and treatment of acoustic neuromas, pituitary tumors, meningiomas, metastatic tumors, gliomas and lymphomas.

Treatment plans range from open surgery, to chemotherapy and targeted radiation therapies such intensity-modulated radiation therapy (IMRT), Gamma Knife or CyberKnife. Support groups are available and our team of nurses and physician assistants are dedicated to the excellent care for our patients.
