Colon cancer is the third most common cancer diagnosed in both men and women in the United States. While regular screening is crucial for detecting colon cancer early, it's also important to understand the various risk factors that can increase your likelihood of developing this disease. In this blog post, we'll explore three key risk factors for colon cancer: age, diet, and family history.
Age as a Risk Factor for Colon Cancer
One of the most significant risk factors for colon cancer is age. The likelihood of developing colon cancer increases significantly after age 50, with the majority of cases occurring in people over the age of 60.
This is why the American Cancer Society recommends that people at average risk for colon cancer begin regular screening, such as colonoscopies, starting at age 45. By detecting and removing precancerous polyps early through regular screening, you can greatly reduce your risk of developing colon cancer.
However, it's important to note that colon cancer can occur in younger people as well. In recent years, there has been a concerning trend of increasing colon cancer rates among younger adults. If you have any symptoms of colon cancer, such as rectal bleeding or changes in bowel habits, it's important to consult with your doctor regardless of your age.
The Role of Diet in Colon Cancer Risk
Another important risk factor for colon cancer is diet. Studies have shown that certain dietary factors can increase your risk of developing colon cancer, while others may have a protective effect.
Diets high in red and processed meats, for example, have been linked to an increased risk of colon cancer. This may be due to the presence of certain chemicals that form during the cooking process, such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs).
On the other hand, diets rich in fruits, vegetables, and whole grains have been associated with a lower risk of colon cancer. These foods are high in fiber, which can help promote regular bowel movements and reduce the amount of time that potentially harmful substances remain in contact with the lining of your colon.
To reduce your risk of colon cancer, it's recommended to limit your intake of red and processed meats, and to focus on a diet rich in plant-based foods. Aim to include a variety of colorful fruits and vegetables in your meals, as well as whole grains like quinoa, brown rice, and whole wheat bread.
Family History and Genetic Risk Factors for Colon Cancer
Finally, family history and certain genetic factors can also play a role in your risk of developing colon cancer. If you have a first-degree relative (parent, sibling, or child) who has had colon cancer, your risk of developing the disease is increased.
Certain genetic syndromes, such as Lynch syndrome and familial adenomatous polyposis (FAP), can also greatly increase your risk of colon cancer. These syndromes are caused by inherited mutations in certain genes that normally help to prevent cancer from developing.
If you have a family history of colon cancer or a known genetic syndrome, your doctor may recommend earlier and more frequent screening, such as colonoscopies starting at a younger age. They may also recommend genetic counseling and testing to determine if you have inherited any cancer-causing gene mutations.
While you can't change your family history or genetic makeup, understanding your risk can help you and your doctor develop an appropriate screening and prevention plan.
DON'T WAIT TO DISCUSS YOUR COLON CANCER RISK WITH YOUR DOCTOR
