What are the symptoms of advanced colorectal cancer

Colorectal cancer is a disease that endangers our health. When many patients go to the hospital for examination, the doctor says it is the late-stage symptoms of colorectal cancer . Many patients wonder why they don’t know about the late-stage symptoms of colorectal cancer. Let’s take a detailed look at the late-stage symptoms of colorectal cancer.

1. The late stage symptoms of right-sided intestinal cancer mainly include indigestion, fatigue, loss of appetite, diarrhea, constipation, or alternating constipation and diarrhea, abdominal distension, abdominal pain, abdominal tenderness, abdominal mass, and progressive anemia. The location of the mass varies with the location of the lesion. The mass of cecal cancer is located in the right lower abdomen, the mass of the ascending colon is located in the right abdomen, the mass of the hepatic flexure of the colon is located in the right upper abdomen, and the mass of the transverse colon is located near the umbilicus. In addition, there may be fever, weight loss, and complications such as perforation and localized abscess. At this time, the lesion has entered the most advanced stage.

2. Left-sided colon cancer is prone to stenosis and progressive intestinal obstruction because the sigmoid colon has a narrow intestinal lumen and forms an acute angle with the rectum. It is often accompanied by stubborn constipation and an increase in the frequency of bowel movements. 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 tumor ruptures, the stool may be stained with blood or mucus. The proximal intestinal tract of the obstruction may form ulcers due to persistent expansion, ischemia and hypoxia, and may even cause perforation. Large amounts of blood and abdominal abscesses may also occur.

3. The late stage symptoms of colorectal cancer are increased bowel movements, thinner stools, blood or mucus, and tenesmus. Since the cancer can invade the sacral plexus nerves, severe pain may occur. If the bladder is involved, symptoms such as frequent urination, painful urination, urgent urination, and hematuria may occur. Cancer invasion of the bladder can form bladder-rectal fistulas. Rectal cancer can also cause intestinal obstruction.

4. Anal canal cancer is mainly manifested by blood in the stool and pain. The late stage of intestinal cancer is that the pain is aggravated during defecation. When the cancer invades the anal sphincter, there may be fecal incontinence. Anal canal cancer can metastasize to the inguinal lymph nodes, so enlarged and hard lymph nodes can be felt in the groin.
