After Hannah Fletcher’s cancer diagnosis, she investigates whether her make up contained asbestos. She was just 41 when she was diagnosed with mesothelioma – a rare cancer that’s very hard to treat. The average life expectancy from diagnosis is just 18 months. She says ‘One of the worst things that I've had to do was write letters to my children in case I died’. Following a 14 hour operation to remove as much of the cancer as possible, Hannah’s doctors advised her to call a lawyer because mesothelioma is almost exclusively caused by exposure to asbestos. This surprised Hannah as she had always had an office job. She didn’t work in construction or industries disturbing asbestos.

After investigating, Hannah’s lawyers realised her asbestos exposure could have been from a surprising source… her talcum powder and make up. Shockingly, it turns out, this issue of asbestos contamination in talc is not new. Talc and asbestos are both natural minerals formed in similar conditions in the ground. This fact is not contentious to any geologist, but the talc and cosmetics industries have sometimes taken a different approach. Thanks to recent court cases, once secret company memos now reveal how the talc industry sought to cast doubt over the science showing their product could be contaminated with the cancer causing substance.

After chronicling the tactics used by big tobacco to delay regulation on smoking and then by big oil to delay regulation on climate change in series 1, Phoebe Keane investigates whether similar tactics have been used again to create the idea that there was a controversy.

Hearing the evidence, Phoebe Keane sends off her own make up to best tested for asbestos. What will the lab find?
