What symptom does colon cancer have 3 times?

(1) Right colon cancer: mainly manifested as dyspepsia, fatigue, loss of appetite, diarrhea, constipation, alternating diarrhea and constipation, abdominal distension, abdominal pain, abdominal tenderness, abdominal mass and progressive anemia. The location of the abdominal mass depends on the location of the cancer. For example, the cecal cancer is located in the right lower abdomen, the ascending colon cancer in the right abdomen, the hepatic flexure cancer in the right upper abdomen, and the transverse colon cancer near the umbilicus. In addition, there may be fever, emaciation, etc. In the late stage, there may be complications such as intestinal perforation and localized abscess.

(2) Left colon cancer: because the sigmoid colon cavity is the narrowest and forms an acute angle with the rectum, and feces have formed solid in the left colon, it is easy to form stenosis. It is often manifested as chronic progressive intestinal obstruction. Most of the patients have intractable intestinal obstruction, and the frequency of defecation can be increased. Because obstruction is mostly in the lower part of sigmoid colon, vomiting is mild or absent, while abdominal distension, abdominal pain, bowel sounds and intestinal type are obvious. When the cancer breaks, blood or mucus can be stained on the outside of the fecal mass, and even pus can be discharged. In addition, massive intestinal bleeding and intra-abdominal abscess may occur.

(3) The main symptoms of advanced colon cancer are increased frequency of defecation, thinner stool, blood and mucus, accompanied by a feeling of urgency or unclean defecation. When the cancer spreads around the rectum and invades the sacral plexus, great pain may appear. If the cancer involves the prostate or bladder, symptoms such as frequent urination, urgency, pain, poor urination and hematuria may appear, and fistulas leading to the bladder or female internal genitalia may be formed. Rectal cancer can also cause intestinal obstruction.
