Pancreatic cancer often present outside the nerve membrane invasion. 34 cases of pancreatic cancer, 34 cases had nerve plexus invasion film, the T and tumor grade. Increased sensitivity to the spinal cord can cause a large number of neurotransmitter release, anger increased the sensitivity of neurons in the spinal cord.
