A 19-year-old woman, who died from breast cancer, has been buried in her home town of Haworth, West Yorkshire.
Sarah Louise McKie, is thought to be the youngest victim of the disease in the UK, and had been fighting the disease for 10 months.
She had both breasts removed but the cancer spread to her spine and brain. Medical experts have called it a million-to-one tragedy.
Pamela Goldberg, chief executive of the charity Breast Cancer Campaign, said: "Girls probably stand more chance of getting struck by lightning than of dying from breast cancer at the age of 19."
Sarah found a lump in her breast last August. She had six courses of chemotherapy and a double mastectomy which failed to halt the spread of the disease.
Her father Malcolm said: "Knowing that it is so rare does not help us."
She had been studying maths at Sheffield Hallam University but planned to change to a teacher training course at Huddersfield in September to be closer to home.
