Diarrhea or alternating diarrhea and constipation in the morning. The changes of defecation habits and stool traits are important indicators for the early detection of colorectal cancer. Because the mass and its secretions stimulate the intestine, people with regular urination and defecation can suddenly become frequent or significantly reduced, constipation and diarrhea occur alternately, diarrhea after getting up in the morning, especially when accompanied by mucus bloody stool, purulent bloody stool, bloody stool in bright red or jam color, or anemia, emaciation and weakness of unknown cause.
Diarrhea with nausea and acid reflux. The early manifestations of gastric cancer are often difficult to distinguish from general gastroenteritis and are easy to be ignored. If you suddenly have unexplained diarrhea, black stool, loss of appetite, weakness, nausea, heartburn, epigastric pain or swelling pain, you should consider the possibility of tumor. Middle aged people over the age of 40, or people with chronic peptic ulcer, should pay more attention and do gastroscopy and other screening in time.
Diarrhea with epigastric pain. Some data show that about 50% of primary liver cancer have diarrhea before diagnosis, ranging from 2 to 20 times a day, which is caused by the disorder of digestion, absorption or secretion caused by the tumor. Therefore, diarrhea is one of the symptoms of liver cancer that can not be ignored, but it has no specificity. The middle-aged and elderly, especially patients with chronic hepatitis or liver cirrhosis, who have discomfort in the upper right of the abdomen, swelling and dull pain in the liver area and gradually aggravate, or loss of appetite and gradually lose weight, should go to the hospital for color Doppler ultrasound, liver function, alpha fetoprotein and other examinations as soon as possible.
Long term chronic diarrhea. Because the pancreas is covered by the stomach and transverse colon, it is difficult to detect by general examination, and the early diagnosis rate of pancreatic cancer is very low. Diarrhoea occurs in some chronic pancreatitis and pancreatic cancer due to insufficient pancreatic secretion. Therefore, unexplained symptoms such as epigastric discomfort, repeated diarrhea, fat diarrhea, dyspepsia, low back pain, jaundice caused by non gallstones and unexplained weight loss should be paid attention to and checked in the hospital in time. In particular, there is a high risk population with chronic smoking history, chronic pancreatitis and family history of pancreatic cancer.
