There are 4 symptoms in the body, and the intestines are seriously "sick"

Rectal cancer: What are the early symptoms?

1. Change in stool color: Abnormal stool color, such as red, can indicate the presence of rectal cancer. This requires prompt medical examination.

2. Change in stool consistency: Rectal tumors can cause compression, making bowel movements challenging. 3. Painful bowel movements: Rectal cancer often presents with pain during bowel movements, particularly in the abdominal area. The pain is continuous and can persist even after defecation. Medical examination is advised if unexplained bowel pain occurs.

4. Abdominal discomfort: Rectal cancer can disrupt intestinal function, leading to abdominal discomfort.
