Other medical conditions, such as impaired kidney or liver function, diabetes, alcoholism, or malnutrition, increase your chances of developing the symptoms, and people over the age of 60 are also at a greater risk. In addition to the symptoms listed above, neuropathy may bring partial or total loss of function or mobility, swelling, and in severe cases, progressive pain. When it occurs from a nerve in the brain, neuropathy may result in cognitive changes such as memory loss or dizziness. The degree and severity depends to some extent on the location of primary and metastatic sites. But close monitoring and preventive strategies can make a noticeable difference.
Every bodily function occurs as a result of the interaction between nerves and other organs.
As a tumor grows and circles around a nerve, or presses on the nerve, it decreases the blood flow to that nerve. This may cause functional changes in the body part controlled by this nerve. Vitamin B6, for instance, is being studied for its potential to decrease neuropathy associated with chemotherapy. Various compounds thought to protect tissues from radiation are being tested in clinical trials. If and when neuropathy is noted, the treatment can be adjusted or stopped, and further damage avoided.
