People are afraid of cancer because they do not know and understand cancer, so they feel fearful when they hear about it. There are three reasons why cancer is scary in general: firstly, the cause is unclear; secondly, the unrestricted growth of cancer cells; thirdly, the metastasis and spread of cancer cells. Specifically for colorectal cancer, modern medicine has a more in-depth understanding of it and has more mastery of some basic characteristics of colorectal cancer. Therefore, we believe that cancer is not always a terminal disease, especially colorectal cancer, which is not only preventable but also curable. Regular colonoscopy is necessary Although the cause of colorectal cancer is still unclear, we have grasped its developmental rules, colorectal cancer does not come directly from the normal intestinal mucosa, but from normal intestinal mucosa to intestinal cancer, there is a precancerous stage, that is, intestinal polyp stage, which takes about 2-7 years. As long as intestinal polyps can be detected and removed at this stage, the cancer process can be stopped and cancer can be avoided. Fecal occult blood swabs, rectal examinations and e-colonoscopy are reliable means to detect intestinal polyps, and e-colonoscopy can also be used to remove intestinal polyps at the same time. Therefore, regular colonoscopy can effectively prevent the occurrence of colorectal cancer. Colonoscopy has been listed as a routine medical examination item in developed countries in the West and in some specific populations in China. For cancer family members, people with previous intestinal polyp disease, people with frequent gastrointestinal discomfort, and normal adults over 45 years old, they are required to have a fecal occult blood swab and rectal examination once a year, and an electronic colonoscopy once every 2-3 years, so that most of the precancerous lesions of colon cancer can be detected, and intestinal polyps can be removed to save us from the trouble of colorectal cancer. Therefore, we say that colorectal cancer can be prevented. A simple fecal occult blood test and anorectal finger examination can detect most colorectal problems. If you have frequent gastrointestinal symptoms, such as bloating, abdominal pain, blood in stool, diarrhea or constipation, and abdominal masses, they may indicate colorectal tumors. Especially the elderly, people with family history of tumor and those who have suffered from bowel cancer or intestinal polyps should be alert. Colorectal cancer is curable Colorectal cancer is no longer a terminal disease, and most patients with middle and early stage colorectal cancer can be cured through a multidisciplinary comprehensive treatment based on surgical radical treatment. We have hundreds of cases that have survived for more than ten years after surgery, and there are even cases that have survived for more than twenty years. Even for advanced colorectal cancer patients, there is still a possibility of cure. Multidisciplinary comprehensive treatment can enable some advanced patients who were considered inoperable in the past to undergo radical surgery after tumor shrinkage; modern laparoscopic minimally invasive surgical techniques for colorectal cancer have greatly reduced trauma and enabled patients of advanced age and poor physical condition who could not tolerate radical surgery for colorectal cancer to undergo radical surgery. Minimally invasive laparoscopic technology can also enable most patients with low rectal cancer who had to have their anus removed in the past to have their cancer removed radically while preserving their anal function. The significance of postoperative adjuvant chemotherapy plus regular review Adjuvant chemotherapy after radical surgery for colorectal cancer can remove a very small amount of cancer cells remaining in the body after surgery, and early postoperative cancer cells are few, grow actively and have high sensitivity to chemotherapy, so timely chemotherapy can prolong postoperative survival time, and regular review is another safeguard measure to detect early signs of recurrence and early treatment, and can also detect multi-originated polyps and multi-originated carcinoma, and then surgical treatment. In conclusion, colorectal cancer is not a scary disease. As long as we work together to raise awareness of it, detect and remove intestinal polyps as precancerous tissues of colorectal cancer as early as possible through regular checkups, we can prevent the occurrence of colorectal cancer; pay attention to the change of bowel habits and gastrointestinal symptoms, and seek regular medical checkups at an early stage, we can detect colorectal tumors at an early stage; once suffering from colorectal cancer, we should not be too nervous, as long as we adopt multidisciplinary treatment based on surgical radical treatment and supplemented with chemotherapy after surgery according to the guidance of specialists. As long as multidisciplinary treatment based on radical surgery, postoperative chemotherapy, regular review, timely detection of recurrence and multi-source lesions, and timely treatment are taken, rectal cancer can definitely be overcome.
