Reactive oxygen species (ROS) are increasingly recognized for their multifaceted roles in cancer development. These molecules influence tumor initiation, promotion, and progression by affecting critical cell signaling pathways.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Reactive oxygen species (ROS) are biologically significant molecules involved in cellular signaling.
  • Emerging evidence highlights the complex involvement of ROS in various stages of cancer.

Purpose of the Study:

  • To elucidate the diverse roles of reactive oxygen species (ROS) in carcinogenesis.
  • To understand how ROS impact tumor initiation, promotion, and progression.

Main Methods:

  • Literature review and synthesis of existing research on ROS and cancer.
  • Analysis of signaling pathways affected by ROS in oncogenesis.

Main Results:

  • ROS contribute to tumor initiation through mutagenic effects.
