Colon cancer is a malignant tumor of the gastrointestinal tract, and it is not a lucky thing to have cancer. The main reason why some people would say that colon cancer is a lucky cancer is because if cancer of the colon can be detected early, through reasonable diagnosis and treatment, most patients have a higher cure rate compared to other malignant cancers. First of all, to a certain extent, colon cancer can be prevented. Most of the colon cancers are caused by some diseases that are not treated in time, which aggravate and cause cancer of colon, such as colorectal adenoma, inflammatory bowel disease and so on. And it takes a long time for these diseases to develop into colon cancer. If active treatment is carried out when these diseases occur, it usually will not lead to cancer, thus playing an effective preventive role and reducing the risk of colon cancer. Secondly, colon cancer can be easily detected at an early stage. Patients with colon cancer are prone to early symptoms, such as change in bowel habits, diarrhea, constipation, or alternating diarrhea and constipation, and some patients may have mucus stool, pus and blood stool, or blood in stool. When patients have these symptoms, they are usually alert and can go to the hospital in time to find out the cause. At this time, early lesions of colon cancer can be easily detected and can be treated as early as possible. Moreover, some communities will conduct colon cancer screening every year, and some early colon cancer patients or people with precancerous diseases can be detected during the screening process, which also facilitates the cure of the disease. Finally, the cure rate of early stage colon cancer is high. With the continuous development of medical technology, most of the early stage colon cancer patients can be cured after active treatment, and the survival time of advanced colon cancer patients can also be extended to a certain extent through active treatment. Therefore, the so-called “lucky cancer” actually means that colon cancer is easy to be prevented, early symptoms can easily appear, and patients who are detected early can be cured after radical surgery.
