Signs of colorectal cancer. The development of any cancer is a process, and colorectal cancer also has some signs.
Many malignant tumors that occur in the colon or rectum, if they can be diagnosed and treated early, the effect is very satisfactory. Therefore, patients with blood in the stool, whether they have hemorrhoids or not, should go to the hospital regularly for rectal or colonoscopy. When you find symptoms such as bloody stools that are common with hemorrhoids, you must consider eliminating other diseases of the intestine. In the treatment of hemorrhoids, attention should also be paid to symptoms such as long-term no significant improvement in symptoms or recurring blood in the stool.
The majority of colorectal cancers occur after middle age, and those located in the left colon often grow circularly, accompanied by changes in bowel habits. When the tumor has erosions, ulcers, and necrosis, it can be manifested as diarrhea, bloody stools, and tenesmus, especially if the tumor is located in the rectum, the main manifestations are bloody stools, increased bowel movements, poor bowel movements, and tenesmus.
Diarrhea and constipation alternately appear to be alert to colorectal cancer: Specifically, there are five major manifestations that can indicate the possibility of colorectal cancer. The first is the sudden change of bowel habits. "People who have normal bowel movements suddenly become frequent defecation, diarrhea or constipation, and sometimes constipation and diarrhea alternately, or often feel anal swelling and abdominal pain. These are abnormal signs and definitely indicate disease. Existence cannot be solved by taking medicine.” Experts pointed out that middle-aged people have the above conditions or are still a little vigilant. Many elderly patients are slow to respond and are not sensitive to pain. Sometimes cancer has perforated and peritonitis has occurred. I felt the abdominal pain was unbearable, so I was willing to seek medical treatment.
The most prominent similar symptom of hemorrhoids and rectal cancer is bloody stools, and the stools are often fresh blood. Especially in the early stage of rectal polyps and rectal cancer (late tumor hemorrhage and necrosis may have pus and blood in the stool), there is no other discomfort except blood in the stool, and it is easy to be mistaken for hemorrhoids. In addition, rectal polyps or rectal cancers can easily compress the rectal veins, which can hinder the return of blood from the rectal veins and cause hemorrhoids.
In addition, symptoms of systemic poisoning such as anemia, weight loss, fever, and weakness are also a major manifestation of colorectal cancer. Because tumor growth consumes nutrients in the body, long-term chronic bleeding can cause anemia in patients; secondary tumor infections can cause fever and poisoning symptoms.
Pay attention to the changes in your usual physical condition. If you find the above symptoms, you must not ignore them, lest these "clues" are ignored by most people. The signs of colorectal cancer are mainly those mentioned above, and I hope everyone can pay attention. (03)
