G63.1: Polyneuropathy in neoplastic disease

Your nerves are damaged.

Many nerves run from the spinal cord and brain to the organs, skin and muscles in the body.

Your nerves or the sheath around your nerves is damaged. As a result, the skin may feel numb or it may tingle, for example. Some organs such as the heart or intestine may no longer be working properly, either. Sometimes it may no longer be possible to walk or stand properly. It may also be that you are in pain or that you are no longer able to move certain muscles. The symptoms usually start in the legs. The symptoms may later spread to other areas of the body.

Your nerves have been damaged by a tumor disorder. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant.
