What are the risk factors for colorectal cancer?

With the progress of the times, people's living standards are getting higher and higher. While you are enjoying life with your family, have you ever thought about paying attention to some cancers? Although modern technology is advanced, due to the hidden nature of colorectal cancer, the symptoms of early cancer patients are extremely subtle. Clinically, most colorectal cancer patients have obvious symptoms in the middle and late stages. Here, we remind our friends that even if you are not sick, you should pay attention to it. Even if you don't consider yourself, you should consider your family. The health of your family is your own health.

Although the exact cause of colorectal cancer is still unclear, clinical findings show that the following factors can greatly increase the risk of colorectal cancer:

1) Age: As age increases, the time that various pathogenic factors stimulate the colon mucosa also increases. Most patients develop the disease after the age of 50.

2) Family history: If a person's first-degree family member, such as a parent, has had colorectal cancer, his risk of developing the disease in his lifetime is 8 times higher than that of the general population [If one of your direct family members (parents, siblings or children) develops colorectal cancer before the age of 50, or if two or more people in your paternal or maternal family have colorectal cancer, then you have a family history of colorectal cancer]. About 1/4 of new patients have a family history of colorectal cancer;

3) History of inflammatory bowel diseases: Certain bowel diseases such as Crohn's disease or ulcerative colitis may increase the risk of colorectal cancer. Their risk of colon cancer is 30 times that of ordinary people;

4) History of colorectal polyps: Most colorectal cancers develop from small precancerous lesions, which are called polyps. Among them, villous adenomatous polyps are more likely to develop into cancer, with a chance of malignant transformation of about 25%; tubular adenomatous polyps have a malignant transformation rate of 1-5%;

5) Genetic background: Familial adenomatous polyposis and hereditary non-polyposis colorectal cancer are caused by mutations in the corresponding genes. These patients not only have a significantly increased risk of developing the disease, but also develop it at a younger age.

The above is an introduction to "What are the risk factors for colorectal cancer?" When the above symptoms appear, patients should go to a regular hospital for treatment. Early detection and early treatment can effectively cure colorectal cancer. People who are related to the pathogenic factors of colorectal cancer are advised to take preventive measures for colorectal cancer.
