Abstract Reactive oxygen species (ROS) are central mediators of cellular metabolism, oxidative stress, and mutagenesis. Their production increases under conditions of metabolic overload, mitochondrial dysfunction, inflammation, and chronic physiological stress. At the same time, oxidative reactions involving ROS generate electronically excited molecular states that emit ultraweak photon emission (UPE), a phenomenon detectable using high-sensitivity photonic imaging systems. Recent experimental studies have demonstrated that living organisms emit measurable levels of photons in the visible spectrum as a direct consequence of oxidative metabolic processes. This work develops a theoretical systems framework integrating four interconnected biological mechanisms: ROS-driven oxidative metabolism, ultraweak photon emission, Ca²⁺ signaling regulation, and systemic stress physiology. The model proposes that tumors may function as localized metabolic attractors characterized by persistent oxidative imbalance, altered calcium regulation, and elevated ROS production. These conditions may generate spatial oxidative fields within tissues that influence neighboring cells through redox-sensitive regulatory mechanisms. Within this framework, chronic psychological or physiological stress becomes a key upstream driver of systemic oxidative load. Activation of the hypothalamic–pituitary–adrenal (HPA) axis and sympathetic nervous system increases glucocorticoid and catecholamine production, which in turn alters mitochondrial activity, immune responses, and redox balance. Sustained stress may therefore raise the baseline ROS level throughout the organism, creating a physiological environment in which local pathological regulatory states can more easily stabilize and propagate. The proposed model integrates established biological mechanisms—mitochondrial ROS production, inflammation, calcium signaling via α2δ-regulated voltage-gated calcium channels, and oxidative mutagenesis—into a coherent theoretical framework describing tumor progression as a propagation of regulatory instability rather than solely genetic mutation. Ultraweak photon emission is interpreted as a physical byproduct and potential spatial indicator of these oxidative processes. The purpose of this work is not to claim that photon emission itself acts as a primary signaling mechanism but to demonstrate how oxidative metabolism, systemic stress, calcium regulation, and metabolic feedback loops may collectively produce tissue-level regulatory fields capable of influencing tumor progression.
