10) Nervous system problems

Some type of lung cancers can cause problems in the nervous system by attacking the body’s own immune system. This can lead to weakness of the muscle groups, numbness in the extremities, tingling sensations over the body, and in severe cases, paralysis.
A characteristic example of a nervous system attack on lung cancer is Lambert-Eaton syndrome, which typically involves the muscles of the hips and causes weakness and muscle wasting. In this syndrome, one of the first signs is the loss of balance and unsteadiness in the arm and legs that causes trouble getting up from the sitting position. Later, the group of muscles around the shoulder and back may become week followed by the weakness of facial muscles.
