Factors like smoking, alcohol consumption, obesity, familial history, and inflammation significantly contribute to the risk of CRC development. Additionally, bacterial infections from organisms like Bacteroides fragilis, Fusobacterium nucleatum, and Helicobacter pylori also play a role in increasing this risk. Conventional treatment methods for CRC typically involve surgery/polypectomy, chemotherapy, and radiotherapy.
