Colorectal cancer is preventable. On the one hand, it means that most colorectal cancers develop from polyps, and on the other hand, because most early cancers can be completely cured. Therefore, the main way to prevent colorectal cancer is to discover colorectal polyp lesions, or discover early colorectal cancer lesions. There are many types of colorectal polyps, and only some polyps will develop into colorectal cancer. Even so, this is a long process, so it gives us plenty of time for intervention. However, clinically, colorectal polyps are asymptomatic. Many patients have become colorectal cancer when they develop symptoms. Therefore, we are required to perform physical examination to find these colorectal polyps when asymptomatic. Encourage people over 35, especially those with gastrointestinal cancer in the family, to have a colonoscopy. If a polyp is found, it can be easily removed endoscopically, and it can be completely cured without surgery or chemotherapy. And find an experienced doctor to evaluate polyps to determine the probability of this polyp becoming cancerous or to determine the time for follow-up review. There is no need to panic when there is early-stage cancer, because most early-stage cancers can be cured, but they need experienced doctors for treatment or post-operative guidance. As for what diet or drugs can prevent colorectal cancer, there is no clear conclusion.
Since many colorectal cancers develop slowly from colorectal polyps, colonoscopy can prevent colorectal cancer from occurring if colorectal cancer polyps are found and removed under endoscopy.
It is found under endoscopy that simple endoscopic resection of colorectal polyps before they have become cancerous can prevent colorectal cancer from occurring
Comment: Because there are polyp lesions in the intestines before colorectal cancer, they may not be clinically symptomatic, so people over 40 should have a colonoscopy to find possible precancerous lesions. People who have a family history of cancer, especially those who have gastrointestinal cancer among family members, should have a colonoscopy. Chronic abdominal pain, mucus in the stool, blood in the stool, positive fecal occult blood, or who have always thought of hemorrhoids should also undergo a colonoscopy. It is very simple to find that the doctor can remove the polyp in more than 20 minutes. After the resection, stay in the hospital for a few days and wait for the wound to develop before being discharged.
