Colorectal cancer affects both colon as well as rectum. Origin source of cancerous tumor can either be in colon or in rectum. But, eventually the tumor spreads to both colon and rectum leading to colorectal cancer. Surgical procedures employed to treat colorectal cancer involve removal of cancerous or malignant tumor. If the tumor has spread to the entire colon or rectum, then the affected organ has to be removed entirely to avoid metastasis (spread of cancer).
Sometimes, healthy portions of colon or rectum surrounding the tumor can be removed in order to eliminate possibility of recurrence of cancer. Surrounding lymph nodes may also be removed and the ends of the colon or rectum will be re-attached to intestines. Surgery is the primary treatment for colorectal cancer. Type of surgery that is to be performed will depend on the stage of colorectal cancer.
Early diagnosis plays an important role in treatment of colorectal cancer. Earlier it is detected, less complex is the surgery type chosen. Also, in early stages, it is possible to cure cancer. But, as it advances, difficulty level of treating cancer rises and chances of getting cured completely reduce.
