Each year nearly 150,000 people in the U.S. are diagnosed with colorectal cancer and around 50,000 die from the disease. Studies have shown that when performed every one to two years in people ages 50 to 80, fecal occult blood tests (FOBT) can help reduce the number of deaths from colorectal cancer by 15 to 33 percent. Because of its ease of use and cost effectiveness, FOBT may have an important role in improving colorectal cancer screening rates and saving lives.
