Experts help everyone understand the late symptoms of colorectal cancer

If colorectal cancer develops to the late stage, it is quite serious. Most people will feel terrified when they hear about the late stage of the disease. So how much do you know about the late stage symptoms of colorectal cancer? Next, let the experts analyze what the late stage symptoms of colorectal cancer are so that everyone will no longer be unfamiliar with it.

The advanced symptoms of colorectal 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.

Since the sigmoid colon has a narrow intestinal cavity and forms an acute angle with the rectum, it is prone to stenosis and progressive intestinal obstruction, often with stubborn constipation and occasional increased 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. These are the late symptoms of colorectal cancer.

The late stage symptoms of colorectal cancer are mainly manifested as increased frequency of 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.

The main symptoms are blood in the stool and pain. The pain worsens 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, which is also a late-stage symptom of colorectal cancer.

The above content is a detailed description of the advanced symptoms of colorectal cancer. I hope everyone can understand them one by one. After knowing these advanced symptoms of colorectal cancer, patients can detect the disease more promptly, and of course it can also be of great help in the later treatment. So please be more vigilant about the advanced symptoms of colorectal cancer mentioned above. I wish all patients can fight the disease to the end.
