Fenbendazole, an anti-parasitic medication, has shown potential as a cancer treatment due to its ability to induce programmed cell death (apoptosis) in cancer cells. Research has demonstrated that fenbendazole can interfere with multiple cellular signaling pathways involved in cancer development and progression, leading to the death of cancer cells. Fenbendazole has been shown to be effective in treating a variety of cancers, including melanoma, lung, and breast cancer, by inhibiting cancer cell growth and spread.
