Environmental Factors Environmental factors such as lifestyle choices, diet, and exposure to carcinogens
play a significant role in cancer development. Carcinogens such as tobacco smoke, ultraviolet (UV) radiation, and certain chemicals cause DNA damage that can lead to mutations in critical genes controlling cell growth and division. Unhealthy lifestyle choices, including poor diet, lack of physical activity, and excessive alcohol consumption, can further exacerbate these risks by weakening the body’s ability to repair DNA damage and maintain normal cellular processes.
Together, these factors increase the likelihood of genetic mutations that disrupt cell regulation, leading to the uncontrolled growth characteristic of cancer.
