H2O2 is a reactive oxygen species (ROS) that can induce oxidative stress in cells. While low levels of ROS can promote cell signaling and proliferation, high levels can lead to DNA damage, apoptosis (programmed cell death), and other cellular dysfunctions. This dual role means that H2O2 can contribute to cancer development and progression, as oxidative stress can lead to mutations and genomic instability.
H2O2 can enhance the effectiveness of certain chemotherapeutic agents by increasing oxidative stress in cancer cells. Additionally, localized delivery of H2O2 has been explored as a means to selectively target and kill cancer cells while sparing normal cells.
Cancer cells often exhibit altered metabolism, leading to increased production of reactive oxygen species, including H2O2. This can result from enhanced mitochondrial activity, increased glycolysis, or other metabolic adaptations that are characteristic of cancer.

Note: many products at lower concentrations act as antioxidants, instead of Prooxidants.

Generally, increased hydrogen peroxide and oxidative stress are associated with poor outcomes, while the specific context and cellular environment can modulate its effects.
