What are the high-risk factors for colorectal cancer?

Colorectal cancer is a common tumor in my country, with an incidence rate second only to lung cancer and gastric cancer. The incidence rate of colorectal cancer in my country is increasing by 4.2% every year. Malignant tumors that usually occur in the colon, rectum, and anal canal are collectively referred to as colorectal cancer. Timely detection of early colorectal cancer is of great significance to the treatment and prognosis of patients. So what are the risk factors for colorectal cancer? The following experts will introduce the risk factors of colorectal cancer in detail for you:

1. Age: Older people are more likely to develop colorectal cancer, especially those over 50 years old. In fact, colorectal cancer can occur at any age. However, more than 90% of colorectal cancer patients are over 50 years old. Only a few patients develop colorectal cancer before the age of 20.

2. Diet: The occurrence of colorectal cancer seems to be related to a high-calorie, high-fat, and low-fiber diet. Many studies are exploring the role of diet in colorectal cancer.

3. Polyps: The mucosal cells of the large intestine may grow into a benign tumor that protrudes from the surface of the intestinal wall. We call it polyps. This is quite common in people over 50 years old. Some types of polyps will continue to evolve into cancer cells, which is the precursor of colorectal cancer.

4. Family history: Having a family member with colorectal cancer is an important risk factor. About 10% of colorectal cancer patients have relatives who have had colorectal cancer.

5. Personal medical history: Studies have shown that women with ovarian, uterine, or breast cancer have an increased chance of developing colorectal cancer in the future. Colorectal cancer patients should prevent themselves from getting colorectal cancer again.

6. People with low physical activity: People who exercise appropriately have a lower risk of colorectal cancer.

7. Drinking and smoking: Smoking may increase the risk of colorectal cancer, and regular drinking (especially beer) has been shown to increase the risk.

The early symptoms of colorectal cancer are not obvious, and the symptoms occur intermittently and incoherently, so they are easily ignored or misdiagnosed as other diseases, thus delaying the best treatment time. More than 90% of patients with early colorectal cancer can be cured, while the survival rate of patients in the late stage is less than 5%. Therefore, mastering some early symptoms of colorectal cancer is very important for early detection and early treatment.
