NET Cancer Day
The diffuse endocrine system is made up of neuroendocrine cells found in the respiratory and digestive tracts. The respiratory tract includes the bronchial tubes and lungs. The digestive tract starts at the mouth and ends at the rectum.
Neuroendocrine cells are also located in endocrine glands, such as the adrenal glands, pancreas, thyroid and pituitary. These cells are also found in the ovaries and the testes.
NET cancers develop when these specialized cells undergo changes causing them to divide uncontrollably and grow into an abnormal tissue mass (tumor).
