Why is the incidence of colorectal cancer high

Everyone should be familiar with the disease of colorectal cancer. Because this disease is very common in our lives, and once it occurs, it will cause great harm to the patient's body. The incidence of this disease is getting higher and higher, so why is the incidence of colorectal cancer so high? The following will introduce to you the causes of colorectal cancer.

Factors that cause colorectal cancer: 1. Dietary factors: Epidemiological studies have shown that diet is an extremely important factor in the development of tumors, because 70% to 90% of tumors are related to environmental factors and lifestyle, and 40% to 60% of environmental factors are related to diet and nutrition to a certain extent.

Factors causing colorectal cancer 2. Occupational factors: Although it is generally believed that colorectal cancer is not an occupational disease, the relationship between occupational factors and the incidence of colorectal cancer still needs to be taken seriously. Among colorectal cancer patients, workers who produce asbestos insulation materials are more common, and animal experiments have also confirmed that swallowed asbestos fibers can penetrate the intestinal mucosa. In addition, in industries such as the metal industry, cotton yarn or textile industry, and leather manufacturing industry, the standardized mortality rate and mortality rate of colorectal cancer are also high.

Factors causing colorectal cancer 3. Disease factors

(1) Colon adenoma: Colon adenoma is a precancerous lesion. Most studies believe that more than 80% of colon cancers occur on the basis of pre-existing adenomas. Therefore, all adenomas found during examination should be removed to prevent the occurrence of colon cancer in the future. However, more than 30% of patients who have colon adenomas removed will develop new adenomas, so close follow-up is required.

(2) Ulcerative colitis: This disease is more common in Europe and America, but the incidence in China has also increased in the past 20 years. Studies have found that the incidence of colorectal cancer in these patients is 5.7 times that of the general population (relative risk). This relative risk is related to the location of the lesion.

The above are some common causes of colorectal cancer in life. There are many reasons for this disease, so when preventing this disease in daily life, you must pay attention to the various causes of this disease. Only in this way can you achieve the goal of effectively preventing colorectal cancer. I hope the above introduction is helpful to you.
