Early symptoms of colorectal cancer

The stomach is also an area that everyone needs to pay attention to, because in recent years, there are also many people with gastrointestinal diseases, and for different patients, the types of gastrointestinal diseases are also different, so the harm caused to the patient's body will also be different. Among them, colorectal cancer has become a more common malignant tumor problem, so what are the early symptoms after colorectal cancer occurs?

In recent years, the incidence of colorectal cancer has shown a clear upward trend. The early symptoms of colorectal cancer are very similar to those of hemorrhoids. Therefore, many patients ignore these signs, thinking that they are just minor problems. They treat them hastily without seeking medical treatment in time. In fact, colorectal cancer and hemorrhoids are completely different.

The blood in the stool is different. The characteristic of hemorrhoids with blood in the stool is that the blood bleeds during defecation, and the blood is bright red, and the bleeding stops on its own after defecation; rectal cancer is bloody in the stool, and in many cases it is mixed with mucus or pus. The color of this blood is darker than that of hemorrhoid bleeding. Rectal cancer will cause changes in bowel habits, such as thinner stools, more frequent stools, or alternating constipation and diarrhea. Rectal cancer is often accompanied by other symptoms. For example, abdominal discomfort, bloating, or persistent pain. Due to tumor consumption, patients may also experience systemic symptoms such as anemia, weakness, weight loss, and low-grade fever. If it is hemorrhoids, it rarely causes these discomforts.

Once suspicious symptoms such as blood in the stool and bowel dysfunction appear, do not easily conclude that you have hemorrhoids. Instead, you should see a specialist in time and do necessary examinations such as digital rectal examination, proctoscopy, and colonoscopy.

Anyone over 40 years old with any of the following symptoms should be classified as a high-risk group: 1. Those with a first-degree relative with a history of colorectal cancer; 2. Those with a history of cancer or intestinal adenoma or polyps; 3. Those with a positive fecal occult blood test; 4. Those with two of the following five symptoms: mucus and blood in the stool, chronic diarrhea, chronic constipation, a history of chronic appendicitis, and a history of mental trauma.
