A brief analysis of the high-risk population for common colorectal cancer

As the incidence of colorectal cancer continues to increase, more and more people are beginning to pay attention to the relevant knowledge of colorectal cancer, especially the high-risk populations for colorectal cancer . So who are the high-risk populations for colorectal cancer? The following will tell you about the common high-risk populations for colorectal cancer.

Generally speaking, the high-risk groups for common colorectal cancer are:

1) Age: As age increases, the time that various pathogenic factors stimulate the large intestine mucosa also increases. Middle-aged and elderly people over 50 years old are a common high-risk group for colorectal cancer.

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 developed colorectal cancer, then you have a family history of colorectal cancer]. People with a family history of colorectal cancer are also at high risk of colorectal cancer.

3) History of intestinal inflammatory diseases: Certain intestinal diseases such as Crohn's disease or ulcerative colitis may increase the chance of developing intestinal cancer. They are also a common high-risk group for intestinal cancer. Their risk of intestinal 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 malignant chance of about 25%; tubular adenomatous polyps have a malignant rate of 1-5%. Therefore, people with a history of colorectal polyps are also a common high-risk group for colorectal cancer.
