The white color of stool in pancreatic cancer is usually due to the fact that the tumor of pancreatic cancer presses the common bile duct and bile can not be excreted to the intestines, thus obstructive jaundice occurs, and the color of stool appears white, terra cotta and so on. In the early stage of pancreatic cancer, the tumor has not invaded the pancreatic duct and bile duct, so the color of stool is normal and light yellow. As the disease gets worse, the patient’s digestive ability also decreases, and the patient may have loose stools and unshaped stools. When pancreatic cancer develops to the point that the malignant tumor compresses the common bile duct, the bile cannot be excreted to the intestines, thus obstructive jaundice occurs, and the color of the stool appears pale, potter’s earth, white and so on. Other conditions can also lead to pancreatic cancer stool white color, and it is recommended that patients seek medical examination in time and deal with them accordingly under the guidance of doctors.
