Reducing Colorectal Cancer Risk: Early Screening and Lifestyle Modifications for Patients with Family History

Your patient has two or more first-degree relatives diagnosed with CRC at any age, what do you recommend?

Screen at age 40 or 10 years prior to youngest person’s diagnosis, whichever comes first, screen every 5 years

If a patient has two or more first-degree relatives diagnosed with colorectal cancer (CRC) at any age, then their risk of developing CRC is increased. In such cases, early colorectal cancer screening is recommended to detect any signs of cancer at an early stage, which in turn improves the chances of successful treatment. The following recommendations would be suggested to this patient:

1. Start screening at a younger age: Usually, the screening for CRC starts at 50 years of age, but in this case, the patient should opt for early screening – which usually starts at age 40 or ten years earlier than their youngest affected relative. A colonoscopy every five years is the preferred screening method.

2. Genetic counseling: The patient should consider genetic counseling to determine if there is a hereditary risk of colon cancer. Some hereditary conditions such as Lynch syndrome and familial adenomatous polyposis (FAP) can increase the risk of CRC. Genetic testing will help in identifying any such conditions.

3. Evaluation of lifestyle factors: The patient should evaluate their lifestyle factors, such as diet, physical activity, and alcohol intake. An unhealthy lifestyle could increase the risk of colon cancer. In such cases, the patient should make lifestyle modifications and incorporate a healthy diet and exercise.

4. Consult with a gastrointestinal (GI) specialist: Consulting a GI specialist should be the next step for patients with increased risk of CRC. A GI doctor specializes in the digestive tract, and they can evaluate any symptoms the patient may be experiencing and provide guidance for early screening.

Overall, early screening for CRC is essential for patients with an increased risk of the disease to prevent or detect cancer in its early stages. It is necessary to follow up with a doctor regularly, maintain a healthy lifestyle, and pay attention to any unusual symptoms to reduce the risk of CRC.
