Age is generally a major factor affecting colorectal cancer

Age is generally a factor that affects colorectal cancer the most, and it usually occurs in the elderly. However, there are many causes of colorectal cancer. Let the authoritative experts explain the causes of colorectal cancer to us. I hope that reading this article will be helpful to you.

The main causes of bowel cancer include:

1. Age: As age increases, the time that various pathogenic factors stimulate the large intestine mucosa also increases. Most patients develop the disease after the age of 50, which is the cause of 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 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 chance of developing colorectal cancer. Their risk of colon cancer is 30 times that of ordinary people. This is a risk factor for intestinal cancer.

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 malignancy of about 25%; the malignancy rate of tubular adenomatous polyps is 1-5%. These are the causes of colorectal cancer.

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. This is also the cause of colorectal cancer.

The above is the explanation given by experts on the cause of colorectal cancer. I hope it can help you answer your questions. Experts suggest that some diseases have no early symptoms or are not obvious. For your health, the best way is to have regular physical examinations to detect the disease early and prescribe the right medicine.
