Explanation:

• Both the statements are correct.
• Silicosis is a long-term lung disease caused by inhaling large amounts of crystalline silica dust, usually over many years.
• Silica is a substance naturally found in certain types of stone, rock, sand and clay.
• Working with these materials can create a very fine dust that can be easily inhaled.
• Once inside the lungs, it causes swelling (inflammation) and gradually leads to areas of hardened and scarred lung tissue (fibrosis).
• Lung tissue that's scarred in this way doesn't function properly.
• There's no cure for silicosis because the lung damage can't be reversed.
• Treatment aims to relieve symptoms and improve quality of life.
• The condition may continue to get worse, leading to further lung damage and serious disability, although this may happen very slowly over many years.
