Its execution is governed by interconnected processes, including redox homeostasis, the intracellular labile iron pool, and amino acid metabolism. In cancer, ferroptosis can operate in opposite directions, supporting tumor progression or tumor suppression.

Ferroptosis is a type of cell death that occurs when there is an overload of iron within the cell, leading toa disruption in vital components of the cellular membrane. In cancer, ferroptosis can play a“double-edged sword” role, where it can be either beneficial or detrimental. There are several factors of ferroptosis that can either promote or prevent cancer from occurring. These factors contribute to pathways that allow it to be studied and manipulated therapeutically for the benefit of treating cancer.  \nAbstract  \nFerroptosis is a non-apoptotic, iron-dependent form of cell death. The characteristic accumulation of membrane lipid peroxides that occurs is controlled by several different mechanisms including redox homeostasis, the intracellular labile iron pool, and amino acid metabolism. In cancer, ferroptosis can contribute to either tumor progression or tumor suppression. When promoted in cancer cells, ferroptosis plays an innately tumor-suppressiverole; however, it can negatively affect anticancer immunity, allowing for tumor growth and progression. Cells that are traditionally known to be resistant to apoptosis and other forms of cell death have demonstrated susceptibility to ferroptosis, making this form of cell death particularly useful in terms of cancer therapeutics. This narrative review will focus on the role of ferroptosis in cancer promotion or prevention and how it can be manipulated therapeutically—whether it be induced or inhibited.  \nKeywords: ferroptosis; cancer; iron homeostasis  \n1. Introduction  \nFerroptosis is an iron-dependent form of programmed cell death that is driven by the accumulation of reactive oxygen species (ROS), leading to the formation of membranedamaging lipid peroxides [1] . This form of cell death is considered to be distinct from other forms, such as apoptosis, pyroptosis, and necroptosis, in both morphological and mechanistic ways [2] . Morphologically, cells undergoing ferroptosis exhibit several changes in their mitochondria, including smaller size, decreased cristae, and much more condensed  \nmembranes [3] . Mechanistically, ferroptosis has yet to be identified as being initiated by executioner proteins, as is seen in many other forms of cell death [4] . Overall, cells undergoing ferroptosis appear to have a reduced cell volume, with a characteristic loss of membrane integrity [5] . The overall process of ferroptosis includes the accumulation of ferrous iron, free radical production, dysfunction of the antioxidant system, and membranebound lipid peroxide formation [6] . The execution of ferroptosis is classified as the oxidation of phospholipids containing polyunsaturated fatty acids (PUFAs) [7] .
