Are black women in South Africa at especially high risk of developing breast cancer from Depo–Proveral?
Yes, it would appear so. A study performed on South African women in 1997 found that 72% of black women had used an injectable progestin contraceptive and that 30% of women had used one for 5 years or more 18. The progestin used most often was either DMPA or norethisterone and these injectable hormones have been used there since the mid 1960s. The study noted that white South African women had a far lower use of these progestin hormones.
