Answer :

Final answer:

Colon cancer screening should begin at age 50 for the general population, age 45 for African Americans, age 40 for those with a personal or family history of cancer, age 50 for those with IBD, and age 25 for individuals with FAP or HNPCC. So, the correct answer is option (a).

Explanation:

The appropriate age for starting colon cancer screening varies between different populations and is tailored according to the risk factors each population faces. The general population should begin screening for colorectal cancer at age 50. However, African Americans are recommended to start earlier at age 45 due to a higher risk. Individuals with a personal history of cancer or with a family history of cancer in a first-degree relative should begin even earlier at age 40. Those with Inflammatory Bowel Disease (IBD) are generally advised to start screening at age 50. For hereditary conditions such as Familial Adenomatous Polyposis (FAP) and Hereditary nonpolyposis colorectal cancer (HNPCC), screening is recommended to begin at age 25 due to the high risk of early onset of the disease.

While different screening methods such as fecal occult blood tests and colonoscopy exist, the decision on when and how to screen should be based on a detailed discussion with a healthcare provider, factoring in individual risk profiles and the pros and cons of each testing method. Lifestyle modifications and regular screenings can be potent tools in not just detecting the disease early but also in reducing the overall risk, especially for those with a family health history of chronic diseases.
