Asbestos is a naturally occurring mineral fiber that was commonly used in building materials until the 1980s, when it was discovered that it poses a significant health risk. Asbestos can cause various respiratory diseases, including lung cancer and mesothelioma. Despite the dangers of asbestos, it can still be found in many homes and buildings today. In fact, it's estimated that up to 50% of all buildings in the UK may contain asbestos.
