Reasons for the surge in colorectal cancer incidence

In recent years, the incidence of colorectal cancer has increased significantly, and most patients are diagnosed at an advanced stage. The main reason for the high incidence of colorectal cancer is mainly related to people's lifestyle habits.

First of all, the occurrence of colorectal cancer is related to the changes in people’s eating habits in recent years, especially the impact of westernized diet.

With the improvement of people's living standards and changes in eating habits, the incidence of colorectal cancer has been increasing year by year, especially in cities. Influenced by the West, people have gradually accepted a Western diet that is high in fat, high in protein, and low in dietary fiber. This type of food contains a lot of saturated fatty acids, which can easily lead to excessive burden on the intestines, disordered flora composition, and promote the generation and development of carcinogens, and the incidence of colorectal cancer has also increased. In addition, during the frying and grilling process of meat, carcinogenic heterocyclic amine compounds and toxic substances can be produced. These substances can stimulate proliferative changes in the intestinal mucosa, leading to cancer.

Secondly, long-term constipation is also a cause of colon cancer.

Due to the high work pressure in modern society, many urban people sit at work every day and lack the necessary exercise. Long-term sitting will lead to reduced intestinal motility, prolonged retention of feces in the large intestine, causing constipation, and increasing the stimulation of fecal carcinogens on the large intestine mucosa. Feces are the garbage of the human body. If they are not removed every day and accumulate in the intestine for a long time, the harmful substances in the feces can easily damage the intestinal mucosa, thereby inducing cancer.

Therefore, here is a suggestion for everyone. People over 40 years old, especially those at high risk with colorectal polyps, ulcerative colitis, and a family history of colorectal cancer should be screened every year. For patients with positive fecal occult blood, colonoscopy can be used for further colorectal cancer screening.
