1. Disruption of Microtubule System: It affects the structure of cancer cells and their ability to rapidly divide.
2. Inhibition of Glucose Metabolism: Cancer cells require glucose to survive, and fenbendazole interferes with this process.
3. Promotion of p53 Gene Expression: p53 is an important tumor suppressor gene that is often deficient in cancer patients.

Additionally, fenbendazole may also eliminate parasites that cause tissue inflammation and fibrosis.
