called silica dust). SILICA DUST AND CANCER Silica dust is harmful when it's breathed in; it is 100 times smaller than a grain of sand, so you can be breathing it without knowing. This can lead to silicosis, chronic obstructive pulmonary disease, kidney disease, and lung cancer. It is estimated that each year 230 people develop lung cancer due to
