4-Changes in Stool Consistency:
Most people associate changes in bowel habits with colon cancer, but subtle changes in stool consistency, such as narrow or ribbon-like stools (pencil stools), can sometimes indicate a blockage in the colon caused by a tumor. This change may occur intermittently and should be monitored.

5-Anemia:
Iron deficiency anemia can develop if colon cancer causes chronic bleeding. This can lead to symptoms such as weakness, pale skin, and shortness of breath. Anemia may persist despite iron supplementation, indicating the need for further investigation.

6-Sudden Onset of Constipation or Diarrhea:
While occasional changes in bowel habits are common, a sudden and unexplained onset of persistent constipation or diarrhea may be a sign of colon cancer. These changes can occur as a result of a tumor obstructing the bowel or altering its normal function.

7-Rectal Bleeding or Blood in Stool:
Rectal bleeding or blood in the stool is a well-known symptom of colon cancer. However, bleeding may be intermittent and vary in severity. It is important not to dismiss any episode of rectal bleeding, even if it stops on its own.

8-Persistent Gas or Bloating:
Chronic gas, bloating, or feeling of fullness despite eating normally can sometimes indicate an underlying gastrointestinal issue, including colon cancer. These symptoms may occur due to a partial obstruction in the colon caused by a tumor.
