19 year old Hawa Mbegu with her mother at her home. Hawa has a violent form of skin cancer, now too advanced to be treated with radiation therapy, even though it is free for albinos. Hawa's brother, who was also an albino, died of skin cancer six years ago at the age of 22. Discrimination against albinos is a serious problem throughout sub-Saharan Africa, but recently in Tanzania albinos have been killed and mutilated, victims of a growing criminal trade in albino body parts fuelled by superstition and greed. Limbs, skin, hair, genitals and blood are believed by witch doctors to bring good luck, and are sold to clients for large sums of money, carrying with them the promise of instant wealth.
