Bowel cancer, also known as colorectal cancer, is a type of cancer that begins in the large intestine (colon) or the rectum. Here's a breakdown of key information:
Understanding Bowel Cancer:
- What it is:
- It develops from the inner lining of the bowel.
- Often starts as growths called polyps, which can become cancerous over time.
- Colon cancer begins in the colon, and rectal cancer begins in the rectum.
- Risk Factors:
- Age: The risk increases significantly with age.
- Family history: A family history of bowel cancer or polyps.
- Diet: A diet high in red and processed meats and low in fiber.

Diagnosis:
- Screening tests:
- Fecal occult blood test (FOBT) or immunochemical fecal occult blood test (iFOBT).
- Colonoscopy.
- Sigmoidoscopy.
- Biopsy: A tissue sample is taken to confirm the diagnosis.
- Imaging tests: CT scans or MRIs to determine the extent of the cancer.
Treatment:
- Surgery: To remove the cancerous tissue.
- Chemotherapy: To kill cancer cells.
- Radiation therapy: To destroy cancer cells with high-energy beams.
- Targeted therapy: Medications that target specific cancer cells.
- Immunotherapy: treatments that help the bodies own immune system fight the cancer.
