environmental carcinogenesis

Environmental carcinogenesis refers to the process by which exposure to certain environmental factors can lead to cancer. These factors include chemicals (like those found in tobacco smoke or pollution), radiation (such as UV rays from the sun), and biological agents (like certain viruses). Over time, these exposures can damage our DNA, leading to mutations that disrupt normal cell growth and division. Not everyone exposed to these factors will develop cancer, as genetic susceptibility and lifestyle choices also play a significant role. Understanding these connections helps in disease prevention and public health efforts.
