Colon cancer risk explained, and how to minimise it
Colon cancer, also known as colorectal cancer, is a common type of cancer that starts in the large intestine (colon). The risk of developing colon cancer is influenced by several factors. Here are some of them:
1. **Age**: The risk of colon cancer increases with age. Most people diagnosed with colon cancer are older than 50.
2. **Family History**: If you have a close relative, like a parent, sibling, or child who has had colon cancer, you might be at a higher risk.
3. **Genetic Syndromes**: Certain inherited genetic disorders like Lynch syndrome and familial adenomatous polyposis (FAP) can increase your risk.
4. **Personal History**: If you've had colon cancer before, you're more likely to get it again. Also, having a history of inflammatory bowel disease, such as ulcerative colitis or Crohn's disease, can increase your risk.
5. **Diet**: A diet high in fat, especially from animal sources, and low in fiber may be linked to an increased risk of colon cancer.
6. **Lifestyle Factors**: Lack of regular physical activity, a low fruit and vegetable intake, a low-fiber and high-fat diet, obesity, alcohol consumption, and tobacco use may increase the risk.
​
Understanding these risk factors is the first step towards reducing the risk of colon cancer. Here are some ways you can minimise the risk:
1. **Dietary Changes**: Adopt a diet rich in fruits, vegetables, and whole grains. These provide dietary fiber, which is linked to a lower colon cancer risk.
2. **Regular Exercise**: Engage in regular physical activity. Exercise may reduce your risk of colon cancer.
3. **Maintaining a Healthy Weight**: If you're overweight, losing weight may help reduce the risk of colon cancer.
4. **Limit Alcohol and Avoid Smoking**: These habits are associated with a variety of cancers, including colon cancer.
5. **Regular Screening**: Regular colon cancer screenings can help detect precancerous polyps, which can be removed before they turn into cancer.
​
Remember, while these strategies can help reduce the risk of colon cancer, they can't eliminate the risk entirely. It's important to discuss your risk factors and screening options with your healthcare provider.
