Experts answer common causes of colorectal cancer

As a common and extremely harmful tumor disease, colorectal cancer brings great pain to patients. What are the causes of colorectal cancer ? Let's ask experts to tell you about the common causes of colorectal cancer.

In general, the common causes of colorectal cancer are:

1. Genetic factors are a common cause of colorectal cancer. There are reports of "family-based colorectal cancer" both at home and abroad. The number of blood relatives of colorectal cancer patients who died of the disease is significantly higher than that of the general population. Some colorectal adenomas, such as multiple familial adenomatosis, are autosomal dominant genetic diseases with a family prevalence rate of up to 50%. If not treated, people are likely to develop colorectal cancer after the age of 10. Recently, some scholars have studied the relationship between tumor suppressor genes and colorectal cancer and found that the susceptibility and pathogenesis of colorectal cancer are both related to genetic factors.

2. Colon adenoma. According to the research on autopsy materials from various places, the incidence of colon adenoma is quite consistent with that of colon cancer. According to statistics, the incidence of colon cancer in patients with one adenoma is 5 times higher than that in patients without adenoma, and the incidence of patients with multiple adenomas is 1 times higher than that in patients with a single adenoma. This is also a common cause of colon cancer.

3. Chronic colon inflammation. It is reported that the prevalence of intestinal cancer is positively correlated with the prevalence of schistosomiasis. It is generally believed that due to schistosomiasis, inflammatory changes in the intestines may lead to cancer in some cases. Other chronic inflammations of the intestines may also lead to cancer, such as ulcerative colitis, which has a 3% to 5% chance of cancer. This may also be the cause of colon cancer.

4. Environmental factors. Studies have shown that among various environmental factors, diet is the most important and is the most important cause of colorectal cancer. The incidence of colorectal cancer is positively correlated with the high fat consumption in food. In addition, it may also be related to the lack of trace elements and changes in lifestyle habits.

The above is an introduction to the common causes of colorectal cancer. I hope it will be helpful to everyone. Understanding and recognizing the causes of colorectal cancer can help patients accept treatment more actively.
