Why can asbestos be harmful?
If you breathe in asbestos fibres, they can become stuck in your lungs. This can lead to lung diseases, especially cancer. But, asbestos is generally only a risk if you disturb or damage it. This can release fibres into the air. If materials have asbestos in them but they're in good condition or unlikely to be disturbed or damaged, it’s usually safer to leave them where they are.
