But let me tell you how it is from someone who knows their life is going to be cut short — someone who, every time they notice a new mole on their chest, is reminded that they'll have to say goodbye to their friends and family long before they're ready," Abi continued. After struggling with headaches and vision problems, the London native was diagnosed with a brain tumor in April 2024. But after undergoing surgery, chemo and radiation, she was told a month later that she had a stage 3 brain tumor, specifically a rare type called anoligodendroglioma, which starts in the central nervous system. https://people-app.onelink.me/HNIa/kz7l4cuf Continuing her social media post about embracing aging, Abi — who serves as an ambassador for the organizationBrain Tumor Research— said, "Please don't wish yourself younger. Don't chastise yourself for showing signs of how much you've lived and loved and smiled over the years." "Your wrinkles, your skin that sags, are souvenirs of some of the best times of your life, and the worst times you thought you'd never survive. But, hey, you did," she continued. Abi Feltham/Instagram Added Abi: "Aging isn't a disaster ... it's not something to fight. It's something your body is meant to do and knows how to do, like breathing or healing a cut or giving birth or, in fact, dying. It means you're still here with a life to live and enjoy, so use it."
