Bowel cancer is likely to be age-related

Bowel cancer is likely to be age-related, and is more likely to occur in the elderly. So what are the other causes of bowel cancer ? Regarding this question, let the authoritative experts explain it to us.

The main causes of bowel cancer include:

1) Sexual history: Certain colon 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.

2) 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.

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%, which is also the cause of colorectal cancer.

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.

The above is the explanation given by experts on the cause of colorectal cancer. I hope it can help you answer your questions. Experts remind everyone that if you suffer from any disease in your daily life, you must not delay treatment. This is very dangerous. Some diseases will worsen or cause other diseases.
