Isla Sneddon, a 17-year-old, died of breast cancer after an urgent referral was downgraded due to her age, despite initial concerns and painful lumps. In 2022, at age 14, Isla was told her breast lumps were likely hormonal; when she returned in 2024 at age 16, an urgent referral was downgraded in line with national guidelines that treat patients under 30 with suspected cancer as routine.
