For now, they live near-normal lives day to day, taking targeted therapy in the form of tablets for as long as it keeps their cancer at bay.

“I’m hopeful that if I can just get through the next two years, then there might be another drug,” Harriet says. “And if I can just get two more years after that, maybe there will be a jab, and two years after that maybe there will be a cure. I always live in hope because if you don’t have hope, you have nothing.”

Fewer options exist for Sophie’s specific type of cancer, but new and promising treatments may be on the horizon. A recent global trial showed that amivantamab used in combination with a different therapy stopped the progression of EGFR-positive lung cancer for more than 40% longer than standard treatment.

The combination was approved in the US in August and Dr Forster is optimistic that it will be made available in the UK next year. “The next best thing is to make primary care professionals, like GPs, more aware that developing lung cancer even if you’ve never smoked is sadly not that uncommon,” he says.

That knowledge might have got Jade diagnosed quicker, but she is reflective. “People talk about cancer being a gift, but the gift is the perspective it gives you,” she says. “My future looks different to how it might have done. All I can do is live for today.”
