UNDERSTANDING COLORECTAL CANCER

What to know

This page provides a starting point for learning about colorectal cancer. Cancer types and individual experiences vary, and information here is not a substitute for personalized medical guidance.

Possible signs

Possible signs include blood in or on stool, persistent bowel habit changes, abdominal discomfort, unexplained weight loss, or fatigue. Early disease may cause no symptoms.

  • Keep track of changes that are new, persistent, or unusual for you.
  • Symptoms can have many causes and do not necessarily mean cancer.

Risk factors

Risk increases with age, some inherited conditions, family history, inflammatory bowel disease, smoking, alcohol use, and certain lifestyle factors.

  • Having a risk factor does not mean a person will develop cancer.
  • Share relevant personal and family history with a healthcare professional.

When to seek guidance

Routine screening is recommended for many average-risk adults starting at age 45 in the United States; timing and test choice should be discussed with a clinician.

  • Ask about tests, screening, or follow-up appropriate to your age and personal risk.
  • Seek urgent care for severe or rapidly worsening symptoms.
