By Colorectal cancer, also known as colon cancer or bowel cancer, is the fourth most common cancer diagnosed in Australia, with over 15,300 new cases in 2023. While lifestyle factors play a significant role in colorectal cancer risk, family history is another crucial factor to consider. As a colorectal surgeon, I understand the importance of understanding your risk profile and taking proactive steps for early detection. This looks into the role of family history in colorectal cancer risk and provides valuable information for men and women seeking guidance on this issue and wanting to know why your annual colonoscopy in Melbourne is critical, from a leading female surgeon specialising in colorectal and pelvic floor procedures.
Family History: A Strong Indicator
Having a close relative diagnosed with colorectal cancer can increase your own risk. Here’s how it works:
- Genetics: Colorectal cancer can be caused by inherited gene mutations. These mutations can be passed down from parents to their children.
- Shared Environment: Familial tendencies towards diet, lifestyle choices, and even gut bacteria composition can also contribute to an increased risk if they are not conducive to good health.
Understanding Your Risk Profile
The following factors associated with family history influence your risk of developing colorectal cancer:
- Degree of Relationship: Your risk is higher if a first-degree relative (parent, sibling, or child) has been diagnosed.
- Age of Diagnosis: If your relative received a diagnosis before the age of 50, the risk is even greater.
- Number of Affected Relatives: Having multiple affected relatives significantly increases your risk.
- Specific Syndromes: Inherited syndromes like Lynch Syndrome (HNPCC) and Familial Adenomatous Polyposis (FAP) are linked to a much higher risk of colorectal cancer.
Importance of Early Detection
Colorectal cancer is highly treatable when detected early. Regular screening through colonoscopies plays a vital role in early detection. Here’s how family history affects your recommended screening schedule:
- Average Risk: The standard screening recommendation for individuals with no significant family history is a colonoscopy at age 50.
- Increased Risk: If you have a first-degree relative diagnosed with colorectal cancer after age 50, you may need to begin screening at age 40.
- High Risk: For those with a strong family history (multiple affected relatives, young age of diagnosis), or a suspected inherited syndrome, a colonoscopy might be recommended even earlier, potentially starting at age 25-35.
Taking Control of Your Health
While family history can influence your risk, it doesn’t dictate your destiny. Here’s what you can do to manage your risk:
- Know Your Family History: Talk to your family members about any history of colorectal cancer.
- Schedule a Consultation: If you have a concerning family history, consult a Melbourne colorectal surgeon to discuss your risk profile and appropriate screening strategies.
- Maintain a Healthy Lifestyle: Diet, exercise, and maintaining a healthy weight can all contribute to a lower risk of colorectal cancer.
- Consider Genetic Testing: In some cases, genetic testing can help identify inherited mutations and refine your risk assessment.
