The exact cause of most GI cancers is unknown, but several risk factors have been identified:
- Genetic Mutations: Changes in DNA can lead to cancer. - Lifestyle Factors: Smoking, alcohol consumption, and a diet high in processed foods and red meat can increase risk. - Chronic Inflammation: Conditions like Crohn's disease and ulcerative colitis can contribute to colorectal cancer. - Infections: Hepatitis B and C increase the risk of liver cancer, while Helicobacter pylori infection is linked to stomach cancer. - Family History: A family history of certain GI cancers can increase risk.
