What are Brain and Central Nervous System (CNS) Cancers?
They are a group of diseases where abnormal cells grow in the brain or spinal cord. When cancer from other parts of the body spreads to the brain, it's called metastatic brain cancer. Brain and CNS cancers happen when cells in these areas start growing out of control. There are many types of brain tumors, and they can be either cancerous (malignant) or non-cancerous (benign). Even benign tumors can cause problems if they grow and press on important parts of the brain. These tumors can affect how the brain works, causing symptoms like headaches, seizures, vision problems, or changes in behavior. The most common types of brain tumors in adults include gliomas (like astrocytomas and oligodendrogliomas), meningiomas, and pituitary tumors. In children, common types are medulloblastomas and ependymomas. Each type of tumor grows differently and may need different treatments.
Treatment
Treatment for brain and CNS cancers usually involves a team of doctors working together. Options can include:
Surgery to remove the tumor
Radiation therapy to kill cancer cells
Chemotherapy drugs.
The exact treatment plan depends on the type of tumor, its location, and how fast it's growing. Living with a brain or CNS tumor can be challenging. Patients often need ongoing care and may have to deal with side effects from the tumor or its treatment. However, new research constantly improves our understanding and treatment of these cancers.
Statistics and Trends
In the United States, it's estimated that about 25,400 new cases of brain and other CNS cancers will be diagnosed in 2024.
Over the past five years (2019-2023), approximately 120,000 to 125,000 people in the US have been diagnosed with brain and other CNS cancers.
Looking ahead five years, if current trends continue, we might expect to see around 26,000 to 27,000 new cases per year by 2029. However, this is just an estimate and could change based on new research or treatments.
History
Brain tumors have been known since ancient times, but our understanding of them has greatly improved in the last century. In the early 1900s, surgery was the main treatment, but it was very risky. The invention of the CT scan in the 1970s and the MRI in the 1980s made it much easier to see brain tumors clearly. This helped doctors plan better treatments. New therapies like targeted drugs and immunotherapy have been developed in recent decades. These treatments try to attack cancer cells while causing less harm to healthy brain tissue. Today, researchers are working on even more advanced ways to diagnose and treat brain cancers.
