Colon cancer, a formidable adversary to health and well-being, has prompted the American Cancer Society (ACS) to craft guidelines for effective colon cancer screening meticulously. These guidelines are essential in fortifying public health against this insidious disease.

Colon cancer screening, emphasized by the ACS, plays a pivotal role in the early detection and prevention of colorectal malignancies. As we delve into the intricacies of these guidelines, it becomes evident that they are tailored to different risk profiles, offering a nuanced approach to safeguarding health.

Guidelines for Individuals at Average Risk

For those at average risk, initiating regular colon cancer screening at the age of 45 is the recommended starting point. Individuals in good health, with a life expectancy exceeding ten years, should continue regular screenings until the age of 75. Between 75 and 85, screening decisions become preference-based, while individuals above 85 are generally advised against further colon cancer screenings.

Determining average risk involves evaluating key factors. People are considered at average risk if they lack:

• A personal history of colorectal cancer or specific polyps.

• A family history of colorectal cancer, inflammatory bowel disease (ulcerative colitis or Crohn's disease.)

• Confirmed hereditary colorectal cancer syndrome.

• Those without a history of radiation to the abdominal or pelvic area for prior cancer treatment fall into the average-risk category.

Test Options for Colon Cancer Screening

Colon cancer screening offers various test options, providing flexibility to individuals based on their preferences and healthcare needs. Understanding these options is essential for informed decision-making.

Stool-Based Tests

• Highly Sensitive Fecal Immunochemical Test (FIT): Administered annually, FIT is a non-invasive test that detects hidden blood in the stool, potentially indicative of colorectal abnormalities.

• Highly Sensitive Guaiac-Based Fecal Occult Blood Test (gFOBT): Conducted annually, gFOBT identifies blood in the stool, aiding in the early detection of colorectal issues.

• Multi-Targeted Stool DNA Test (mt-sDNA): This test, recommended every three years, evaluates stool samples for genetic mutations associated with colorectal cancer, offering a comprehensive screening approach.

Visual (Structural) Checkups

• Colonoscopy: A thorough examination of the colon, recommended every ten years, provides a comprehensive view of the entire colon and enables the removal of precancerous polyps.

• CT Colonography (Virtual Colonoscopy): Conducted every five years, this non-invasive procedure employs advanced imaging to visualize the colon, making it a viable alternative for those opposed to traditional colonoscopies.

• Flexible Sigmoidoscopy (FSIG): Administered every five years, FSIG examines the lower part of the colon, aiding in the early detection of abnormalities.

Individuals at Increased Risk

Due to an elevated risk profile, specific individuals necessitate a more proactive stance, commencing colorectal cancer screenings before the age of 45. This group includes those exhibiting signs such as a personal history of colorectal cancer, specific polyps, family history of colorectal cancer, inflammatory bowel disease, and hereditary colorectal cancer syndromes. Recognizing the heightened vulnerability of this demographic, the ACS advocates for early intervention to curtail potential threats.

Crucial Signs for People at High Risk

• Hereditary Reasons: Individuals with a family history of colorectal cancer or hereditary syndromes like familial adenomatous polyposis (FAP) or Lynch syndrome require heightened vigilance. Early screenings have become imperative to address genetic predispositions preemptively.

• Previous Cases of Colon or Rectal Cancer: Those who have battled colon or rectal cancer in the past must remain vigilant. Regular screenings aid in monitoring and mitigating the risk of recurrence.

• Removal of Polyps During Last Checkup: A history of polyp removal during the last screening necessitates a closer watch. It is crucial to ensure that the colorectal landscape remains free from potentially precancerous growths.

• Radiation for Previous Cancer Treatment: Individuals who underwent radiation for a prior cancer case, especially in the abdominal or pelvic region, must adhere to rigorous screening protocols. Radiation exposure elevates the risk, warranting a proactive stance.

• Inflammatory Bowel Disease: Those grappling with inflammatory bowel diseases like Crohn's disease or ulcerative colitis face an increased risk. Regular screenings are instrumental in monitoring the colorectal health of this vulnerable demographic.

• Suspected Genetical Reasons: Individuals with suspected genetic predispositions to colorectal cancer require a meticulous screening regimen. Early detection becomes a linchpin in managing and mitigating inherited risks.
