What are the common causes of colon cancer

Colon cancer is very common. Colon cancer is mainly a tumor that occurs in the intestine. So, what are the most likely factors to induce colon cancer in life? Let's learn about it from the following article.

1. Age of onset: Most cases of colon cancer can only occur after the age of 50. People over the age of 50 must pay more attention to changes in their bodies, and annual physical examinations are particularly important. Therefore, this is a factor that induces the cause of colon cancer.

2. History of colon disease: Certain colon diseases such as Crohn's disease or ulcerative colitis may increase the chance of colon cancer. Their risk of colon cancer is 30 times that of ordinary people.

3. Polyps: Most colon 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 rate of about 25% for colon cancer, and a malignant rate of 1-5% for tubular adenomatous polyps. This is also the main factor that induces the occurrence of colon cancer.

4. Family history: If a person's first-degree relatives, such as parents, have had colon cancer, his risk of developing colon cancer in his lifetime is 8 times higher than that of the general population. About a quarter of new patients have a family history of colon cancer.

The above explanations are all about the causes of colon cancer. I hope everyone can have a more comprehensive understanding of how colon cancer is caused. If you have other questions about colon cancer, you can contact our online experts to answer your questions.
