What are the symptoms of advanced colon cancer

Colon cancer is one of the common malignant tumors. In the late stage, colon cancer is prone to the spread and metastasis of tumor cells. The late stage symptoms of colon cancer are often accompanied by signs of liver metastasis such as jaundice, ascites, edema, as well as cachexia, rectal fossa masses, supraclavicular lymph node enlargement and other manifestations of distant spread and metastasis of tumors. The clinical manifestations of late stage symptoms of colon cancer may vary depending on the location of the cancer.

1. The main symptoms of advanced colon cancer are increased bowel movements, thinner stools, blood and mucus, accompanied by a feeling of tenesmus or incomplete defecation. When the cancer spreads to the rectum and invades the sacral plexus, severe pain may occur. If the cancer involves the prostate or bladder, symptoms such as frequent urination, urgency, pain, difficulty urinating, and hematuria may occur, and fistulas leading to the bladder or female internal reproductive organs may form. Rectal cancer can also cause intestinal obstruction.

2. Right colon cancer: Main symptoms include indigestion, 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, such as cecal cancer in the right lower abdomen, ascending colon cancer in the right abdomen, hepatic flexure cancer in the right upper abdomen, and transverse colon cancer near the umbilicus. In addition, there may be fever, weight loss, etc. In the late stage, there may be complications such as intestinal perforation and localized abscess.

3. Left-sided colon cancer: Since the sigmoid colon is the narrowest and forms an acute angle with the rectum, and the feces have already formed solids in the left colon, it is easy to form stenosis. It often manifests as chronic progressive intestinal obstruction. Most patients have intractable constipation, and the frequency of bowel movements may also increase. Since the obstruction is mostly in the lower part of the sigmoid colon, vomiting is mild or absent, while abdominal distension, abdominal pain, bowel sounds and intestinal patterns are obvious. When the cancer ruptures, the outside of the feces may be stained with blood or mucus, and even pus may be discharged. The intestinal tract proximal to the obstruction may form ulcers or even perforations due to persistent and significant swelling, ischemia and hypoxia. In addition, massive intestinal bleeding and intra-abdominal abscess formation may occur.
