Symptoms of late-stage recurrence of colon cancer

What are the symptoms of late-stage recurrence of colon cancer? According to relevant experts, for colon cancer, we should not only pay attention to its treatment effect, but also pay attention to relevant prevention work. With the increasing number of patients with colon cancer, many people are threatened with life because of colon cancer. Then, let the relevant experts give you a detailed introduction to the symptoms of late-stage recurrence of colon cancer patients.

Left-side colon cancer: Since the sigmoid colon is the narrowest and forms an acute angle with the rectum, and since the stool has already solidified in the left colon, strictures are prone to form. It often presents as chronic progressive intestinal obstruction, and most patients have persistent constipation, and may also have an increased frequency of bowel movements. Since the obstruction is mostly in the lower sigmoid colon, vomiting is mild or absent, while abdominal distension, abdominal pain, intestinal sounds, and intestinal patterns are obvious. When the cancer ruptures, the outside of the stool 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.

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.

The main symptoms of advanced colon cancer are increased bowel movements, thinner stools, blood and mucus, and 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.

Through the above experts' common sense introduction to the symptoms of late-stage recurrence of colon cancer patients, I hope that the common sense of colon cancer introduced by the above experts can help friends. In addition, I would like to remind all patients not to be discouraged even if the disease has reached the late stage. As long as patients insist on treatment and maintain confidence, I believe that the disease will be cured soon.
