Bowel cancer (colon and rectal) occurs when “the abnormal cells continue to divide, producing more and more,” explains oncology consultant Catherine Aitken.
People in their 60s and over are at greater risk, but it can also affect young adults. The colon is part of the large intestine, while the rectum is the passage that connects the colon to the anus.
Symptoms of colon cancer include:
• The appearance of blood in the stool.
Bleeding from the back passage.
Unexplained diarrhea or constipation that lasts three weeks or more.
Unexplained weight loss.
Abdominal pain.

• Back ache.
Feeling that your bowels are not emptying properly after a bowel movement.
• Unexplained tiredness, dizziness or shortness of breath.
• Anemia.
And if a carcinoid tumor is blocking the intestine, you may experience:
Constipation.
Bloating
Abdominal pain.
Fatigue and may vomit.
The American Cancer Society added that “stool narrowing that lasts more than a few days” could be a warning sign of bowel cancer.
In the early stages of colon cancer, a surgeon can remove the cancer from the bowel along the boundaries of healthy tissue. This is called local excision.
Alternatively, the surgeon can remove all or part of the colon that contains the tumors. This is known as a colectomy.
Once the tumor is removed, the surgeon ties the ends of the intestine together.
