Cure Rates for the Four Stages
There are several stages of colon cancer, known as stage I, II, III, and IV. In stage I the growths have spread from the inner lining, but not beyond the outer wall. In this early stage if the tumor is successfully removed the five-year rate of survival is 93%.
In the next stage the cancer growth is larger and has spread to the outer wall of the colon. The tumor can be removed surgically, and sometimes chemotherapy is used as well to try and prevent the cancer from reoccurring. The five-year survival rate in this case is 78%.
Once the cancer has reached the lymph nodes it is in stage III. Surgery is used if possible to remove all growths from the large intestine and nodes, then chemotherapy. It is possible that radiation therapy would be necessary if the tumor has invaded surrounding tissue as well. The five-year rate survival is 64%.
Once the cancer reaches the fourth stage the chance that the cancer will be cured drops dramatically. In stage IV it has spread to other organs such as the lungs or liver. The five-year survival rate is only 8%.
Knowing what the cure rates are is important for people who are diagnosed with colon cancer, but also for everyone who is at risk for this disease. It is obvious that when a growth is caught at the beginning the likeliness of being cured is very high. Doing what is in your control to prevent colorectal cancer, or at least the progression of a cancerous growth, is essential for ensuring successful treatment. Eat a high-fiber diet, exercise, and get regular screenings once you reach middle age.
