Colorectal Cancer remains one of the most common cancers in the United States, but it is also one of the most preventable and treatable when detected early. According to the American College of Gastroenterology, approximately 4.4% of men (1 in 23) and 4.1% of women (1 in 25) will be diagnosed with colorectal cancer during their lifetime. In 2025 alone, more than 154,000 Americans are expected to be diagnosed, and over 52,900 people may die from the disease. Yet screening could prevent or detect early more than half of these deaths.
One of the most important facts patients should understand is how dramatically outcomes improve with early detection. When colorectal cancer is found at an early, localized stage, the five-year survival rate is approximately 91%. This is because screening can identify and remove precancerous polyps before they ever develop into cancer, or detect cancer when it is still highly treatable.
An important message is simple but critical: never ignore new or concerning bowel symptoms. Everyone, regardless of age, should speak with their physician if they experience symptoms such as blood in the stool, changes in stool shape or size, persistent changes in bowel habits, or rectal pain. It can be embarrassing to discuss these things; however, a short conversation with a doctor can lead to earlier diagnosis and better outcomes.
Lifestyle choices also play a significant role in colorectal cancer risk. Research shows that over half (54%) of colorectal cancers in the United States are linked to modifiable risk factors, including excess body weight, physical inactivity, smoking, heavy alcohol use, diets high in red or processed meat, and diets low in fiber, calcium, and whole grains. Healthy lifestyle choices and regular screening together can significantly reduce risk.
In recent years, a concerning trend has begun to emerge. According to the Colorectal Cancer Alliance, despite improved outcomes with screening for older adults, colorectal cancer is the only major cancer increasing in people under age 50. Unfortunately, 75% of younger patients are diagnosed at an advanced stage, when treatment is more difficult, and survival rates are lower. For those with metastatic disease, the five-year survival rate drops to about 13%. Because of this trend, colorectal cancer has become the leading cause of cancer death in adults under 50 and the second deadliest cancer overall.
The key message is clear: screening saves lives. Regular screening beginning at age 45 for average-risk adults and earlier for those with certain risk factors can detect problems before symptoms even develop.
If you are due for screening or have noticed new or concerning bowel symptoms, speak with your doctor. Early detection remains one of the most powerful tools we have in preventing and successfully treating colorectal cancer.
