Early detection is critical in reducing death from colon cancer; researchers have discovered four essential symptoms that people under 50 are most likely to suffer, including stomach pain, rectal bleeding, diarrhea, and iron shortage. 

Colon cancer rates are increasing among young people, and researchers have identified four symptoms that people under 50 are most likely to experience prior to being diagnosed with the disease. These symptoms include abdominal pain, rectal bleeding, diarrhea, and iron deficiency. The risk of colon cancer nearly doubles with the presence of a single one of these symptoms, and having two or more symptoms greatly increases the risk. Early detection is crucial in preventing death from the disease, as young people are often diagnosed at advanced stages. The Centers for Disease Control and Prevention recommend screening for colon cancer starting at age 45, and individuals with a family history of the disease should talk to their doctor sooner. Lifestyle factors such as diets low in fiber and high in processed meat, and obesity may contribute to the rise in colon cancer rates among young people.
