A brain tumor is a collection, or mass, of abnormal cells in your brain your skull, which encloses your brain, is very rigid any growth inside such a restricted space can cause problems brain tumors can be cancerous (malignant) or noncancerous (benign) when benign or malignant tumors grow, they can cause the pressure inside your skull to increase. Brain and spinal cord (also known as central nervous system, or cns) tumors can be benign or malignant explore the links on this page to learn more about the many different cns tumor types and how they are treated we also have information about brain cancer statistics, research, and clinical. A primary brain tumor is a tumor which begins in the brain tissue if a cancerous tumor starts elsewhere in the body, it can spread cancer cells, which grow in the brain these type of tumors are called secondary or metastatic brain tumors. In adults, secondary brain tumors are far more common than are primary brain tumors any cancer can spread to the brain, but common types include: breast cancer colon cancer kidney cancer lung cancer melanoma risk factors in most people with primary brain tumors, the cause of the tumor is not clear.
Benign brain tumors are noncancerous malignant primary brain tumors are cancers that originate in the brain, typically grow faster than benign tumors, and aggressively invade surrounding tissue although brain cancer rarely spreads to other organs, it can spread to other parts of the brain and central nervous system. Brain tumors are categorized as primary or secondary a primary brain tumor originates in your brain many primary brain tumors are benign a secondary brain tumor, also known as a metastatic brain tumor, occurs when cancer cells spread to your brain from another organ, such as your lung or breast.
Brain and spinal cord (also known as central nervous system, or cns) tumors can be benign or malignant explore the links on this page to learn more about the many different cns tumor types and how they are treated we also have information about brain cancer statistics, research, and clinical trials.
A brain tumor is a mass or growth of abnormal cells in your brain many different types of brain tumors exist some brain tumors are noncancerous (benign), and some brain tumors are cancerous (malignant.
People with a brain tumor may experience the following symptoms or signs sometimes, people with a brain tumor do not have any of these changes or, the cause of a symptom may be a different medical condition that is not a brain tumor.
