A simple at-home test could cut colorectal cancer death risk by 43%

Summary

Long-term data from more than 376,000 people in Sweden found that those who participated in colorectal cancer screening had a 43% lower risk of dying from the disease. The results support the value of completing at-home stool-based screening when offered.
