Terry died in February 2022 from causes unrelated to cancer.
Six months later, despite having undergone preventative bowel surgery, Jeanette attended a routine screening appointment where doctors discovered an ulcer.
Further tests revealed terminal, inoperable, stomach cancer. She died four weeks later.
Hannah said: “It’s hard enough losing somebody, but then to have lost that person to something that was caused by the same mutation that you carry, it kind of hits you again. It’s a proper kick in the stomach.”
After losing her mum, Hannah said she went into “survival mode”, and transferred her care to specialists at St Mark’s Hospital in London.
Every year, medics monitor the growth of polyps – knowing at some point, a decision will have to be taken to undergo the same surgery that Jeanette had.
Hannah said: “They don’t like to pull the trigger too soon on operation, because they know how life-changing it can be for people.
“We try and make light of the situation. Every time I go I’m like, ‘are we all right for another year?’
“And the consultant will go, ‘yeah we haven’t got to have that conversation yet’.”
She added: “Ultimately, I’m waiting for him to turn around to me after one of my appointments and say we’ve got to have a conversation with a surgeon now.
“People will say to me all the time, ‘how do you continue to be positive, and how do you continue to live with something that is like a ticking time bomb?’
“I suppose if I let it take over, then it could consume your every waking thought.”
