Many people think that "ten men and nine hemorrhoids", a little blood in the stool is not worth fussing about, delay in going to the hospital, waiting until the bleeding is getting more and more, and getting thinner, often lose the opportunity for treatment. So remember! Blood in the stool is often an early "sign" of colorectal cancer, so we must not be careless!
In China, colorectal cancer is a common malignant tumor of the digestive tract. It includes various types of colon and rectal cancer, and the incidence is second only to gastric cancer and esophageal cancer; in some large cities, due to the "westernization" of eating habits, colorectal cancer exceeds gastric cancer And the trend of esophageal cancer, another trend is that the age of onset is getting younger and younger, and it is not uncommon for colon cancer patients around 20 years old! Rectal cancer is more common in colorectal cancer, accounting for about 50% to 60%.
Since there is no specific manifestation in the early stage of the disease, only the stool is bloody, so many people mistake it for hemorrhoids, colitis or colonic dysfunction. Early diagnosis of colorectal cancer is the key to treatment. Early colorectal cancer undergoes radical surgical resection, and its 5-year survival rate can reach 90%.
In the diagnosis of colorectal cancer, the digital rectal examination is the easiest method, which can be known by just wearing gloves for digital anus examination; barium enema or colonoscopy can also be used. In particular, the colonoscope can directly see whether there is cancer in the large intestine and the location and size of the cancer, and it can also take a biopsy specimen for pathological biopsy to determine whether the lesion is malignant or benign, and the degree of malignancy, which is the most accurate Method of diagnosis.
