Josie: My Cancer Curse (2011)

This poignant documentary follows 18-year-old Josie Bellerby, a gorgeous, fun-loving, typical teenager except for one thing: her mum carries a hereditary gene that has cursed their family for generations, killing her great-grandmother and her mother. Josie's Mum Julia was one of the first in the UK to test positive for the gene and decided to have drastic surgery - to remove both her breasts.
