The most obvious sign of colon cancer

There is generally no so-called most obvious sign of colon cancer. Depending on the clinical stage of colon cancer patients, a variety of symptoms may appear clinically.

Colon cancer refers to a malignant tumor of the digestive tract originating from the colon epithelium. Its etiology is still unclear, and most of them develop from adenomatous polyps. The clinical symptoms of early-stage colon cancer patients are not typical. A few patients will have abdominal pain and bloating. As the disease progresses, patients with mid-stage colon cancer will experience atypical symptoms such as abdominal pain and discomfort, blood in the stool, and alternating constipation and diarrhea. Eventually, colon cancer patients will have distant metastasis, and respiratory symptoms such as coughing, coughing up blood, and chest tightness may occur, as well as brain symptoms such as headache, vomiting, and limb paralysis. Some patients with advanced colon cancer may also experience systemic symptoms such as weight loss, fatigue, and fever.

When atypical intestinal symptoms such as abdominal distension, bloody stools, diarrhea, and constipation appear repeatedly clinically, it is generally recommended to go to the hospital as soon as possible and have a professional doctor perform relevant auxiliary examinations, such as routine blood tests, routine stool tests plus occult blood tests, or colonoscopy examinations to clarify the specific cause, so as to detect colon cancer lesions early and provide corresponding treatment in time.
