For decades, lung cancer has been viewed as a disease of older men who smoked. Now, cases among young women are on the rise and doctors are baffled. Could air pollution be behind it?

Towards the end of 2019, Becca Smith’s life was full and hectic. At 28, she had taken on a unit in Chester to convert into a yoga studio, poured in all her savings and hired teachers, while at the same time working as a personal trainer. Her days started at 5am; she was driven, stressed, excited, and had no time for the back pain that just would not subside.

“It kept moving around,” she says. “Every day it would be in a different part of my back. I was strapping on heat packs and ice packs just to get to work.” Smith saw her GP, her physiotherapist and a chiropractor, all of whom suspected a torn muscle. “What really worried me,” she says, “the worst-case scenario, was a slipped disc.” One day in March 2020, the pain was so intense that Smith took to her bed, fell asleep and woke with a crashing migraine and blurred vision. Her mum took her to the optician who shone a light behind Smith’s eyes, saw haemorrhaging and sent her straight to the hospital. Once there, Smith was admitted, and over the course of a week, had an MRI, a CT scan, and a biopsy taken from the cells in her back.
