The hallmarks of cancer describe the fundamental biological capabilities that cancer cells acquire during the multistep development of human tumors. This influential framework was first introduced by Douglas Hanahan and Robert Weinberg in their landmark 2000 paper. It was significantly expanded in 2011 (“The Next Generation”), refined with new dimensions in 2022, and further updated in 2026 with Hanahan’s review “Hallmarks of Cancer—Then and Now, and Beyond”  ( Cell 2026 ,  Cell 2000 ,  Cell 2011 ,  AACR 2022 ). A thorough understanding of the problem is half the solution. In cancer biology, this principle highlights why the hallmarks framework remains so powerful: by clearly defining the core traits that allow cancer to develop, sustain itself, evade defenses, and spread, it offers a structured roadmap for decoding disease progression and uncovering targeted therapeutic strategies. Note: Cancer cells exhibit a distinct set of biological characteristics that set t...

Abstract Background: Cancer has historically been defined by genetic alterations driving uncontrolled proliferation. However, metabolic reprogramming is now recognized as a fundamental characteristic of malignant cells that supports survival, proliferation, and interaction with the tumor microenvironment. Recent reviews have conceptualized metabolic alterations as emerging hallmarks of cancer physiology. Objective: We propose a comprehensive set of metabolic hallmarks of cancer , synthesizing recent literature on glucose metabolism, mitochondrial function, metabolite signaling, and metabolic‑immune interactions. Methods: We integrated insights from high‑impact reviews in cancer metabolism (e.g., Cell Metabolism, Molecular Cancer, Frontiers in Oncology) to define ten metabolic hallmarks with mechanistic and clinical relevance. Results: The ten hallmarks include: (1) Aerobic glycolysis; (2) Mitochondrial reprogramming; (3) Lactate accumulation; (4) Metabolic immune suppression; ...
