Overview of Colorectal Cancer
Most colorectal cancers start as a growth on the inner lining of the colon or rectum called a polyp. Over time, some polyps can turn into cancer. Regular screening tests are vital for prevention.
Warning Signs
- Persistent change in bowel habits (diarrhea or constipation).
- Rectal bleeding or blood in your stool.
- Persistent abdominal discomfort (cramps, gas, or pain).
- A feeling that your bowel doesn't empty completely.
- Unexplained weakness or fatigue.
- Unintended weight loss.
Therapeutic Approach
Treatment depends largely on the stage of cancer, though surgery is common for localized tumors.
Surgery (Colectomy)
Removal of the affected part of the colon and nearby lymph nodes.
Adjuvant Chemotherapy
Often used after surgery to kill any remaining cancer cells.
