Tumores cerebrales Un tumor que comienza y crece en el cerebro se llama tumor cerebral primario. Estos reciben su nombre del tipo de célula o la parte del cerebro en donde comienzan a crecer. Un tumor cerebral secundario es un cáncer que se ha propagado (metastásico) al cerebro desde otra parte del cuerpo. Hay muchos tipos diferentes de tumores cerebrales. Los tumores se clasifican en grupos basándose en el lugar en el que crecen en el cerebro, el tipo de tejido cerebral que afecta y si el tumor es cáncer (maligno) o no lo es (benigno). Los tumores cerebrales pueden aparecer a cualquier edad y pueden causar diferentes síntomas dependiendo de su tamaño y ubicación. Tumores tipo glioma Un tipo común de tumor de cerebro en adultos es un glioma. Los tres tipos más comunes de gliomas son: • Astrocitoma • Oligodendroglioma • Oligoastrocitoma Sigue en la próxima página Aprenda más sobre los cuidados de su salud.
2 Glioma tumors develop roots that grow into the nearby normal brain tissue. The roots are unable to be seen with a MRI (Magnetic Resonance Imaging) or any other type of x-rays. Gliomas are unable to be cured with surgery because tumor cells that are not seen will remain after the tumor is removed. This type of tumor can spread to other areas of the brain. They rarely spread to other parts of the body. Treatment options for brain tumors may include: surgery, radiation or chemotherapy. Your doctor will talk with you about the type of treatment that is best for you. Grades of Gliomas Tumors are graded based on how the tumor cells look under a microscope. A piece of the tumor will be needed to determine the tumor grade. Grading is a system used to describe how abnormal or aggressive the tumor cells look. The lower the grade the more normal the tumor cells look. The higher the grade the more abnormal the cells look. With treatment, a brain tumor may grow back at some point in time. Types of Gliomas Astrocytoma Astrocytoma is the most common type of glioma. Astrocytomas are tumors that start in the “astrocytes” (star-shaped cells that make up the “glue-like” or supportive tissue of the brain). Grades of Astrocytoma tumors: • Grade I – Pilocytic Astrocytoma is an uncommon slow growing tumor that is found most often in children. • Grade II – Low Grade Astrocytoma is a low-grade glioma. This type of tumor usually affects younger adults. Although these tumors are low-grade and less aggressive, they can grow with or without treatment which may cause symptoms and harm to the brain. • Grade III – Anaplastic Astrocytoma is a high-grade tumor. This type of tumor grows faster and is more aggressive than grade II astrocytomas.
