Cancer of the brain
Brain cancers fall into two broad categories:
- Primary brain tumours: where the cancer forms from brain cells
- Secondary brain tumours: where the cancer has spread to the brain from an existing tumour in another part of the body such as the lung, breast, prostate, colon or kidney.
Secondary brain tumours are the most common kind of brain cancer.
Brain cancers are given different names, depending on the part of the brain in which they develop:
- Cancers that develop in the brain coverings (the meninges) are called meningioma.
- Those that develop in the neurological supportive tissue (the glial cells) are called glioma.
- Those that develop in blood vessels are called haemangioma.
- Those that develop in bone are called osteoma.
- Those that develop in the pituitary gland are known as pituitary adenoma.
- Some brain cancers are present at birth (craniopharyngioma, teratoma) and are due to abnormal development.
