Colorectal cancer ranks among the most common cancers worldwide, with a significant number of diagnoses annually. While many cases stem from environmental factors and personal lifestyles, approximately 5-10% of patients inherit the disease genetically.
 
Genetic testing unveils inherited abnormalities or mutations, identifying around 10 diseases predisposing individuals to colorectal cancer, including Lynch syndrome, familial adenomatous polyposis, and Peutz-Jeghers syndrome.
 

Who should undergo colorectal cancer genetic testing?

• Individuals under 50 with colon or rectal cancer
• Those under 50 with endometrial cancer
• Individuals with cancer in multiple organs or bilateral cancer
• Those with a family history of early-onset colorectal cancer or multiple affected relatives
• Those with a family history of Lynch syndrome-associated cancers
• Those diagnosed with over 10 intestinal polyps or with a family history of such
• Individuals over 18 seeking to assess their genetic risk

 

Why undergo colorectal cancer genetic testing? 

Genetic testing aids prevention and treatment precision, enhancing survival chances:

• Identifying inherited abnormalities allows proactive disease prevention planning and enables relatives to assess their own risks.
• Detection of abnormal genes informs tailored treatment strategies, such as precision medicine, minimizing side effects.

 

How to reduce colorectal cancer risk:

• Consult a medical geneticist for risk assessment and prevention planning if there's a family history of colon cancer or numerous intestinal polyps.
• Seek a gastroenterologist specializing in hereditary colorectal cancer if inherited abnormalities are identified.
• Begin colonoscopies at 45, following medical advice. Those with family history or genetic predisposition may need earlier screenings.
• Maintain a healthy lifestyle by eating well, exercising regularly, and avoiding smoking and excessive alcohol.
