Colon Cancer Warnings: What to Watch For
Health Points
- Colon cancer can have subtle or awkward symptoms, but early detection saves lives.
- Key warning signs include rectal bleeding, iron-deficiency anemia, and unexplained weight loss.
- Doctors recommend starting screening at age 45, or earlier if you have risk factors.
Colon cancer is often accompanied by noticeable warning signs, though talking about them can be uncomfortable for many people.
Medical experts stress the importance of not overlooking potential symptoms, especially given the rise in colon cancer among younger adults.
“People are maybe sometimes uncomfortable about talking about that part of their body,” Dr. Jennifer Inra explains.
“People are sometimes nervous about the screening tests.”
Bleeding, especially rectal bleeding, is a major concern that should never be ignored, regardless of possible causes like hemorrhoids.
According to Dr. Daniel Chung, “Any kind of blood would be considered to be abnormal until proven otherwise.”
Other symptoms to be mindful of include iron-deficiency anemia, which can appear on routine blood tests, persistent abdominal pain or discomfort, and a noticeable change in stool shape.
Feeling the constant urge to have a bowel movement without result, known as tenesmus, and unexplained weight loss are also important signals to discuss with your doctor.
Current guidelines suggest beginning colorectal screening at age 45 for those at average risk, and screening rates have increased significantly in recent years.
Don’t put off discussing these issues with your healthcare provider—being proactive can make all the difference for your long-term health.
