What are the causative factors that lead to colon cancer

Intestinal cancer is one of the more common cancers. Many people will be affected by the intestinal tract after suffering from intestinal cancer. So, what causes intestinal cancer? Let's explore the causes of intestinal cancer from the following article.

1. Age: With the increase of age, the time that various pathogenic factors stimulate the colon mucosa also increases. Most patients with colorectal cancer develop the disease after the age of 50. Therefore, this is also one of the causes of colorectal cancer.

2. Family history: This is also a cause of colorectal cancer. If a person's first-degree family member, such as a parent, has had colorectal cancer, his risk of developing colorectal cancer 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. Genetic background: Familial adenomatous polyposis and hereditary non-polyposis colorectal cancer are caused by mutations in the corresponding genes. Patients with this type of colorectal cancer not only have a significantly increased risk of developing the disease, but also develop it at a younger age. This is also a common cause of colorectal cancer.

The above is a detailed description of the causes of colorectal cancer. I hope it can help everyone understand the knowledge of colorectal cancer and cure it in time. If you have other questions about colorectal cancer, you can contact our online experts to answer your questions.
