Key Indicators and Early Warning Signs of Colorectal Cancer
Early detection of colorectal cancer is essential for effective treatment. Watch for signs like rectal bleeding, dark stools, and bowel changes. Regular screening from age 45 can save lives by catching the disease early, when treatment options are more effective. Consult your doctor if symptoms persist.

Colorectal cancer impacts the large intestine, which plays a vital role in digestion. It typically begins with benign growths known as polyps that may evolve into malignant tumors over time. Recognizing early warning signs is crucial for timely diagnosis.
Important symptoms to monitor include rectal bleeding, dark or tarry stools, and noticeable changes in bowel patterns. Often, symptoms are subtle at first, appearing only in advanced stages when cancerous cells develop and spread.
Symptoms to watch for include:
Significant shifts in bowel habits, such as severe constipation or diarrhea
The presence of dark or blood-stained stools, or elongated, thin stools
Rectal bleeding and abdominal cramping
Sensation of incomplete bowel emptying or urgency
Persistent abdominal discomfort or pain
As tumors grow, symptoms may worsen, leading to:
Pelvic pain in advanced stages
Bloating or abdominal discomfort
Unexpected weight loss and reduced appetite
If symptoms persist for a long time, seek immediate medical attention. Regular screening is vital since early-stage symptoms are often absent. The American Cancer Society recommends screening starting at age 45. Early detection significantly improves survival rates, with 90% of early-detected cases leading to a five-year survival.
