Yes, environmental toxins can indeed cause cancer. Carcinogens such as benzene, asbestos, and certain pesticides can lead to mutations in DNA, promoting the development of cancer. Histologically, tissues exposed to carcinogens may exhibit dysplasia, which is a precursor to cancer. Over time, these dysplastic cells can progress to malignancy, characterized by uncontrolled cell proliferation and the ability to invade surrounding tissues. Identifying these changes through histological examination is crucial for early diagnosis and treatment.
