5 factors contribute to the cause of colorectal cancer

Colorectal cancer can cause great harm to people's physical health, especially colorectal cancer can lead to death. Understanding the causes of colorectal cancer is very helpful in preventing it. So, what are the causes of colorectal cancer ? Let's ask an expert to introduce the causes of colorectal cancer to you, I hope it will be helpful to you.

1) Causes of colorectal cancer and history of disease : Certain colon diseases such as Crohn's disease or ulcerative colitis may increase the chance of developing colorectal cancer. Their risk of colon cancer is 30 times that of ordinary people.

2) Age : As age increases, the time that various pathogenic factors stimulate the colon mucosa also increases, and most patients develop the disease after the age of 50. This is one of the causes of colon cancer.

3) 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 malignancy of about 25%; the malignancy rate of tubular adenomatous polyps is 1-5%.

4) Genetic background : Familial adenomatous polyposis and hereditary non-polyposis colorectal cancer are both 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.

5) 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.
