Haptoglobin genotypes and malaria comorbidity in breast cancer and healthy Nigerian women.

The results of the study show low Hp 2-2 genotype relative to other genotypes in breast cancer patients; we conclude that low Hp 2-2 genotype is associated with lower malaria risk in breast cancer Nigerian women. It is important to further understand the roles malaria, Hp, and other genotypes play in the pathogenesis of aggressive breast cancer commonly seen in Nigerian women.
