C70.9: Malignant neoplasm: Meninges, unspecified

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

On the outside of the brain and spinal cord there are three thin meninges (linings). A tough meninx, the dura mater, is on the outside. Below that are two soft meninges.

You have cancer in the linings around the brain and the spinal cord.

Not every cancer is the same. There are cancers that develop quickly. You may then quickly feel seriously ill. But there are also cancers that progress slowly. You may then feel generally unwell or weak, or even have no symptoms at all to start with. This cancer can make you behave differently than usual, for example. It may also no longer be possible to move or feel certain areas of the body properly. You may also have seizures. A seizure makes the muscles twitch uncontrollably.

Please note: This ICD code may also derive from the ICD-O system. If this is the case, there are usually additional letters and numbers in addition to the code. It starts with the letter M, followed by 4 digits and then a slash. There is another digit after the slash.

If it is an ICD-O code, then this does not describe a malignant cancer in all cases. The last digit after the slash gives you more detailed information about this:
