7 early signs of colon cancer

Colon cancer is a grave medical condition that affects many people annually. It starts as polyps or growths in the inner lining of the colon. Early detection is crucial for successful treatment. This is possible when one is aware of the early warning symptoms. Here are some early signs of colon cancer that should not be ignored. Being vigilant about these indicators can lead to timely medical intervention and increase the chances of a positive outcome.

Changes in bowel habits
One of the earliest and most common signs of colon cancer is a noticeable change in bowel habits. This may manifest as persistent diarrhea, constipation, or a combination of both. Individuals may also experience a feeling of incomplete evacuation after a bowel movement. Any significant and unexplained alterations in regular bowel patterns should be brought to a healthcare professional’s attention.

Blood in stool or rectal bleeding
Rectal bleeding or blood in stool is a significant red flag for colon cancer. While this symptom may be attributed to various benign conditions, it should never be dismissed lightly. In this case, the blood may appear bright red or darker in color and could be visible in the stool or on toilet tissue.

Abdominal discomfort or pain
Persistent abdominal discomfort, cramps, or pain can be early signs of colon cancer. This discomfort may be characterized by a constant ache, sharp pains, or a feeling of fullness or bloating. While there are many possible causes for abdominal discomfort, it can be indicative of colon cancer if it occurs along with other symptoms.

Iron-deficiency anemia
Colon cancer can cause internal bleeding, which, over time, may result in iron-deficiency anemia. Anemia can cause weakness, persistent fatigue, and paleness of the skin. In such cases, blood tests generally reveal lower-than-normal levels of red blood cells and hemoglobin.

Fatigue and weakness
Individuals with colon cancer often experience persistent fatigue and weakness. This can result from the body diverting energy to fight the disease, as well as from potential anemia due to internal bleeding. While fatigue is a common symptom in many conditions, a healthcare evaluation is warranted if it is persistent, severe, or accompanied by other concerning signs.

Narrow stools
Changes in stool shape and consistency can be a subtle sign of colon cancer. Narrow, pencil-thin stools may be an indication of a narrowing or obstruction in the colon. While this symptom can be caused by other factors, such as benign colon conditions, it should not be ignored if it occurs along with other prominent symptoms of colon cancer.

Frequent gas and bloating
While occasional gas and bloating are normal, persistent and unexplained gas or bloating can be one of the early signs of colon cancer. This occurs when the tumor disrupts the natural flow of gas through the colon. As a result, the gas accumulates in the abdomen, leading to frequent bloating and discomfort.
