Colon Cancer Symptoms: 5 Warning Signs You Shouldn't Ignore

Colon cancer, also known as colorectal cancer, begins in the large intestine (colon) or the rectum. It often starts as small, non-cancerous clumps of cells called polyps that can develop into cancer over time. Detecting colon cancer early significantly improves the chances of successful treatment. However, many people may not experience symptoms in the early stages, or they might mistake them for less serious conditions. Understanding the potential warning signs is crucial for timely diagnosis and intervention.

Understanding Colon Cancer: Why Awareness Matters

Colon cancer is a serious condition, but it is often treatable when caught early. Awareness of its potential symptoms empowers individuals to seek medical attention promptly. Risk factors for colon cancer include age, a family history of the disease, certain genetic syndromes, inflammatory bowel diseases, and lifestyle choices. While screening tests like colonoscopies are vital for early detection, recognizing symptoms can also prompt necessary investigations, especially for those who might not yet be due for routine screening.

Warning Sign 1: Persistent Changes in Bowel Habits

One of the most common and significant indicators of a potential issue in the colon is a noticeable and lasting change in bowel habits. This isn't just an occasional upset stomach;it refers to a persistent alteration in the way your bowels function. This can manifest as new-onset or persistent diarrhea, constipation, or a change in the consistency of your stool (e.g., stools that are narrower than usual, often described as pencil-thin). Any such change that lasts for more than a few days or weeks warrants attention, particularly if it's accompanied by a feeling of incomplete emptying after a bowel movement or an urgent need to go.

While it can be attributed to benign conditions like hemorrhoids or anal fissures, it is also a potential sign of colon cancer. Blood might appear bright red on toilet paper or in the toilet bowl, or it could be dark red or black, indicating blood from higher up in the colon. Sometimes, blood isn't visible but can be detected through a fecal occult blood test. Regardless of its appearance, any instance of blood in your stool or rectal bleeding requires immediate medical evaluation to determine the underlying cause.

These sensations can be vague but tend to be chronic, meaning they recur frequently or are constantly present. While many conditions can cause abdominal discomfort
