Colorectal cancer trends, symptoms, and prevention

Overview

Colorectal cancer remains a major global health challenge, representing roughly 10% of all cancer cases. According to World Health Organization data, there are approximately 1.9 million new cases and 935,000 deaths annually.

Medical experts continue to monitor a rise in diagnoses among younger populations, attributing this trend to environmental factors such as smoking, pollution, and diets characterized by low fiber and high consumption of ultra-processed foods. To combat this, the American Cancer Society suggests screening begin between ages 45 and 50, noting that individuals with first-degree relatives diagnosed at a young age face higher genetic risks.

Clinical focus has expanded to include more specific warning signs that are often difficult to detect because they mimic less serious conditions. While visible blood in the stool and changes in bowel patterns—such as persistent constipation or diarrhea—are key indicators, experts highlight other critical symptoms. Dr. Ketan Thanki of the MemorialCare Todd Cancer Institute emphasizes that “unexplained weight loss” is a significant symptom requiring evaluation.

Additionally, Dr. Fola May of the David Geffen School of Medicine at UCLA notes that while not all polyps are cancerous, “all colorectal cancers begin as polyps.” Because early-stage polyps can be asymptomatic or extremely small, regular screening is essential for detection. Other potential indicators include abdominal pain, fatigue, anemia, and iron deficiency.
