Research has kept the survival rate of small bowel cancer at five years, and the percentage of a victim surviving in 5 years is dependent on how early the cancer is diagnosed and treated. If detected and treated early, the survival rate stands at 87%. If the cancer is discovered when it has spread to surrounding cells or organs, the rate stands at 76%. If discovered when it has spread too far areas of the body, then the 5-year chance is at 42%
