When polyps are found in the colon, it's a serious matter that few can laugh about. These growths, much like tenacious chives, may reappear even after surgical removal, leading to the need for vigilant monitoring. Despite regular check-ups and surgical interventions, why do doctors still emphasize the risk of cancer? The underlying reasons might surprise you.
The Distant Kinship Between Polyps and Cancer
1. Varying Risk Levels Among Different Types
Adenomatous polyps, often likened to toxic weeds among the harmless chives, carry a significant risk. Approximately 70% of colorectal cancers originate from these adenomas. In contrast, inflammatory or hyperplastic polyps are generally benign and pose little threat.
2. Location Determines Risk
The location of a polyp within the colon can significantly influence its potential for malignancy. Polyps located in the rectum or sigmoid colon, which are more accessible and exposed, have a 2-3 times higher chance of becoming cancerous compared to those in the ascending colon. This is akin to chives growing better in a sunny spot than in a shaded corner.
Surgical Removal: A Beginning, Not an End
1. The Critical Information in Pathology Reports
The post-surgery pathology report, which may indicate "low-grade" or "high-grade" intraepithelial neoplasia, is crucial. This information determines the frequency of follow-up colonoscopies, whether it be every three months or every three years.
2. Residual Tissue and Recurrence
If the base of the polyp is not completely removed, there is a high likelihood of recurrence. This is why it is essential to have the procedure performed by an experienced endoscopist, ensuring thorough removal and reducing the chances of new growths appearing at the same site.
Three Daily Practices to Prevent Cancer
1. Protecting Your Gut Microbiome
A diet rich in colorful vegetables (about 300 grams daily) and probiotic-rich, unsweetened fermented dairy products can help maintain a healthy gut microbiome, which is key in preventing malignant transformations. Avoid processed meats, as they can disrupt this balance.
2. A Balanced Exercise Regimen
Combining 150 minutes of moderate-intensity aerobic activity with 10 minutes of high-intensity interval training each week can reduce the recurrence rate of polyps by up to 40% compared to sedentary individuals. Simple activities like brisk walking until slightly out of breath can be highly effective.
3. Timely and Regular Screening
For the general population, the first colonoscopy should be conducted at age 50. However, if high-risk polyps are detected, screening should begin earlier, possibly around age 35. Don't wait for symptoms like rectal bleeding; by then, the situation may be more complex and require more extensive treatment.
