It is important to recognize the symptoms of early colon cancer

Colon cancer is a common tumor disease, and its incidence rate is second only to stomach and esophageal cancer. Only by knowing the early symptoms of colon cancer can we detect and treat colon cancer early. So, what are the symptoms of colon cancer? Let's learn about it together.

Colon tumors are easily misdiagnosed. In the early stages, when the frequency of bowel movements increases and the stool contains mucus, pus and blood, it is easy to misdiagnose it as dysentery, enteritis or hemorrhoids, thus losing the opportunity for early radical treatment and resection.

The clinical features of early colorectal cancer are mainly blood in the stool and changes in bowel habits. When the cancer is confined to the rectal mucosa, blood in the stool is the only early symptom in 85% of cases, but unfortunately it is often not taken seriously by patients. At that time, a rectal finger examination can often touch a mass. In addition to the common systemic symptoms such as loss of appetite, weight loss, and anemia, patients with mid- and late-stage colorectal cancer also have local irritation symptoms of the cancer such as increased bowel movements, incomplete bowel movements, frequent bowel movements, and tenesmus. The enlargement of the tumor can cause narrowing of the intestinal cavity and signs of intestinal obstruction. What are the early symptoms of colon tumors? In the earliest stage, there may be symptoms of abdominal distension, discomfort, and indigestion-like colon tumors, followed by changes in bowel habits, such as increased bowel movements, diarrhea or constipation, and abdominal pain before defecation. Later, there may be mucus stools or mucopurulent bloody stools. Appendicitis and ileocecal tumors are both common clinical diseases.

Colon tumors present with obvious right lower abdominal pain. According to foreign clinical data, the incidence of appendicitis and ileocecal tumors coexisting is 11% to 15%; while domestic scholars have proposed that 6.6% of colon tumors present with symptoms of acute appendicitis as the earliest manifestation, especially in patients over 50 years old. If there is a history of acute appendicitis and a right lower abdominal mass, the presence of colon tumors should be considered.

The disease usually occurs at an older age, with a slow onset. The patient's general condition is poor, the fecal occult blood test is positive, anti-inflammatory treatment is ineffective or only temporarily improves, and relapses occur from time to time. Barium enema can show irregular destruction and filling defects of the intestinal mucosa. In addition, B-ultrasound or CT can be used for differential diagnosis.

After reading the above introduction to the early symptoms of colon cancer, I believe everyone has already known the early symptoms of this disease. We remind everyone that if you find the above symptoms, you should choose a regular medical institution for treatment as soon as possible.
