Cell death in cancer

# Cell death in cancer *Published: 2026 Apr 16* "Evasion of cell death" is a hallmark of cancer, enabling transformed cells to withstand oncogenic and therapeutic stress. Restoring cancer cell death is an appealing strategy but requires a deep understanding of cell death programs. Over the past two decades, the cell death field has expanded from apoptosis to include necroptosis, pyroptosis, ferroptosis, and other emerging programs, reshaping cancer biology and revealing therapeutic opportunities. While apoptosis remains the primary radiation- and chemotherapy-induced cell death program, non-apoptotic programs can drive inflammatory responses and orchestrate the interplay among tumor, stroma, and immune components, influencing immunotherapy outcomes. Ferroptosis, an iron-dependent, lipid peroxidation-driven cell death modality, lacks a canonical induction signal and arises from perturbations in lipid, iron, and redox metabolism. This review presents a unified framework for understanding the roles of major cell death programs in cancer development, progression, and treatment response, as well as addressing resistance to cancer cell death and immune suppression.
