The statement of “6 signs of peritoneal cancer in early stage” is unscientific. Early stage of peritoneal cancer usually lacks typical clinical symptoms, which makes it difficult to distinguish peritoneal cancer from other digestive system diseases. Early stage of peritoneal cancer usually does not show typical clinical symptoms, and the most common symptoms such as abdominal distension, increased abdominal circumference, abdominal pain and other non-specific symptoms will only be noticed by patients when the disease has developed to a certain degree. In peritoneal cancer, abdominal pain is also manifested as self-conscious abdominal distension or discomfort, which is not enough to play the role of differential diagnosis. In addition, some digestive system diseases such as hepatitis and cirrhosis of liver can also cause clinical symptoms of ascites, abdominal distension and abdominal discomfort, so the so-called early signs cannot be used to diagnose peritoneal cancer. For early detection of peritoneal cancer, it is recommended to undergo regular medical checkups and cancer screening, and go to the hospital as soon as possible for consultation and treatment if there is any discomfort, so as to improve the prognosis.
