Symptoms and current status of colon cancer

Do you know what colon cancer is? Do you understand the current status of colon cancer? Do you know the symptoms of colon cancer? With these questions, let's listen to what the experts say:

The occurrence of colon cancer is related to chronic colon diseases. Patients with chronic colon inflammation such as ulcerative colitis have a higher chance of developing colon cancer than the general population. In the process of proliferative lesions, inflammation is often accompanied by chronic ulcers or the formation of inflammatory polyps, which then become cancerous. According to general statistics, the incidence of colon cancer in patients with colon polyps is 5 times that of patients without colon polyps. The incidence of cancer in familial multiple intestinal polyposis is even higher, indicating that genetic factors are involved in the occurrence of colon cancer.

According to the world epidemiological survey, the incidence of colon cancer is the highest in North America, Western Europe, Australia, New Zealand and other places, ranking first and second among visceral tumors, but the incidence is very low in Asia, Africa, Latin America and other places. In recent years, data from various places show that with the improvement of people's living standards and changes in dietary structure, the incidence of colon cancer in my country has been increasing year by year.

Colon cancer used to attract little attention in China, but now in some fast-growing cities, the incidence of colon cancer has increased significantly. According to the officially published data, it has risen from the sixth place to the third or fourth place (on par with liver cancer). For women in cities, the incidence of colon cancer is definitely ranked third. Shanghai started registering colon cancer patients relatively early, and the statistics are relatively accurate. From 1973 to 1993, the incidence of colon cancer in Shanghai increased by 87%, an average annual increase of 4.2%, which is close to the situation in Western countries and is considered to be above the medium level. The good side of economic improvement is that people's physical fitness has improved and their health level has improved, but the side effect also comes with it, that is, the increase in "rich diseases". For example, the increase in the incidence of colon cancer is related to changes in living habits and dietary structure. At present, in some developed cities across the country, people's dietary structure and living habits are very close to those in the West. For example, more people take the elevator, fewer people climb the stairs, more people take the car, and fewer people walk, and the fat content of meat in the dietary structure has increased.

Due to the lack of knowledge about colon cancer, most of the patients who visit hospitals for colon cancer are in the middle or late stages, and the five-year survival rate after surgery is less than 50%. Colon cancer has an insidious onset, and there may be no symptoms in the early stages. When patients present with bloody stools, intestinal obstruction, and progressive anemia, the lesions have mostly progressed to the middle or late stages. It is also quite common for patients to delay their condition by treating hemorrhoids, enteritis, and dysentery before colon cancer is diagnosed. In fact, colon cancer is not terrible if it can be detected and treated in time. Therefore, it is recommended that people strengthen their health awareness and have regular health checks, especially those with risk factors, such as intestinal polyps, family history of cancer, history of pelvic radiotherapy, and chronic diarrhea. They should have regular proctosigmoidoscopy and full colonoscopy. Domestic and foreign studies have shown that conducting a census of asymptomatic people is the only way to detect early colon cancer and improve the cure rate.

Through the above introduction, I believe you must have understood something.
