2. Blood in the Stool
Seeing blood when you use the bathroom should not automatically be attributed to hemorrhoids.
Colon cancer can cause bright-red blood or darker blood mixed with the stool. However, many other conditions can also cause rectal bleeding, so proper evaluation is important.
If you notice unexplained bleeding, contact a healthcare professional rather than trying to determine the cause yourself.
3. Unexplained Abdominal Pain or Cramping
Persistent abdominal discomfort, cramping, bloating, or pain can sometimes accompany colon cancer.
These symptoms are common and usually have causes other than cancer, but they become more concerning when they are persistent, worsening, or accompanied by changes in bowel habits or blood in the stool.
4. Unexplained Weight Loss
Losing weight without intentionally changing your diet or exercise routine should always be investigated.
Unexplained weight loss can occur with many illnesses, including several types of cancer. It is especially important when it occurs together with other digestive symptoms.
5. Persistent Fatigue or Weakness
Feeling unusually tired for weeks without an obvious explanation can sometimes be related to colon cancer.
One reason is that slow bleeding from the digestive tract can contribute to iron-deficiency anemia, reducing the blood’s ability to carry oxygen efficiently.
