What is Colorectal Cancer?
Colorectal cancer is the commonest cancer diagnosed in Singapore. Treatments of colorectal cancer include surgery, chemotherapy and radiotherapy.
Surgery is the main treatment for colorectal cancer because it has been shown in scientific study to be usually the most effective with the highest cure rates. Sometimes a combination of chemotherapy and/or radiotherapy is used together with surgery to achieve cure in more advanced cases.
Most colorectal cancer surgery can be performed by minimal invasive (keyhole) surgery. There is a big difference in colon cancer surgery compared to rectal cancer surgery. In general, colon cancer surgery is simpler, faster and more straightforward compared to rectal cancer surgery which can be much more difficult.
Most colon cancer surgery can be performed by removing a section of colon and joining the remaining ends. Rectal cancer surgery also aims to do that but the proximity to the anus increases the difficultly level to achieve both cancer clearance as well as being able to join back the colon to the anus. Rectal cancer surgery is also made more difficult because the rectum lies in a small and confined space within the bony pelvis that is crowded with other (genitourinary) organs making surgery more challenging.
