If you or someone you know has been diagnosed with secondary brain cancer, we can provide the information you need, from understanding the cancer itself, to choosing the right treatment, to finding support.

The brain and spinal cord are known as the central nervous system. The brain controls all the functions in your body. Different areas of your brain control different areas of your body.
Like other organs, your brain is made up of cells. These are called neurons and are a type of nerve cell. These cells communicate within your brain and with parts of your body by sending nerve impulses or messages through your nervous system. In this way, your brain is connected to your entire body.
Your brain and spinal cord are covered and protected by three layers called the membranes. These separate your brain from your skull. Between two of the membranes is an area called the subarachnoid space. This space contains fluid called cerebrospinal fluid (CSF).
Cancer that starts in the brain is called primary brain cancer. But cancer that spreads to your brain from somewhere else in your body is called secondary brain cancer. The primary cancer is where the cancer started, for example, breast, lung or bowel. Cancerous tumours are made up of millions of cancer cells. Sometimes these cells break up and travel through your bloodstream or lymphatic system to other parts of your body. When these cells build up to form another tumour somewhere else in your body, this is called a secondary cancer or metastases.
It is hard to say how common secondary brain cancer is. But listed below are some of the main types of cancer that often spread to the brain:
