7. Unmotivated weight loss.
At a more advanced stage of the disease, the tumor “steals” energy and the body can lose about 5 kg in six months without changing its diet.
8. General weakness
The combination of weight loss and high energy expenditure causes constant fatigue that is not explained by lifestyle.
9. Heaviness or pain in the anal region:
If the pain is located in the distal part of the rectum, it manifests itself as pain and a feeling of pressure during defecation. It is often accompanied by blood in the stool.
10. Nausea and vomiting.
Intestinal obstruction disrupts digestion and leads to persistent nausea, vomiting, and loss of appetite, which do not improve with diet.
Important: Colorectal cancer begins asymptomatically. Annual checkups with a gastroenterologist are essential for early detection.
