Q: Is asbestos cancerous?

• <div><p>Asbestos is absolutely cancerous. In fact, around 4% of all lung cancer cases are the result of asbestos exposure.

Q: How long does testing take?

• <div><p>Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.</p></div>

Q: Is asbestos still used in siding?
