Common early signs of colorectal cancer: Colorectal cancer is the general term of colon cancer and rectal cancer, and people with unhealthy lifestyle, family genetic history and chronic intestinal diseases are the high-risk group of colorectal cancer. What are the common signals of colorectal cancer? 1. Blood in stool. Because the tumor in the intestinal cavity will rupture and bleed when stimulated by feces, so blood in stool or positive fecal occult blood is often an early signal of colorectal cancer. During physical examination, the stool test indicates “OB positive”, after excluding hemorrhoids, we should pay high attention to the possibility of intestinal tumor. Reminder: many rectal cancer patients are mistakenly treated as hemorrhoids in early stage! 2. Change in bowel habits. Diarrhea and constipation without any regularity, sudden appearance and change of stool habit excluding gastroenteritis should be considered for colonoscopy. Reminder: Early colorectal cancer can be cured! 3. Abdominal pain. Abdominal pain caused by colorectal tumor is mostly in the middle and late stage, and abdominal pain of colorectal cancer is mostly found in the right side of the abdomen, when there is unexplained persistent abdominal pain on the right side, the possibility of colorectal cancer should be highly suspected! 4. Abdominal mass. Under normal stool condition, if you feel an abdominal mass, especially on the right side of the abdomen, ultrasound should be performed in time for primary screening and further colonoscopy if necessary. CEA (carcinoembryonic antigen) is a common test item in health checkups, and most of the normal reference values are 0–5. If CEA is higher than normal, you should seek consultation from oncologists!
