Approved breast cancer drug offers hope for the treatment of blood disorders

A new study provides an explanation as to why blood cancers are more common in men than in women, revealing that estrogens regulate the survival of stem cells that give rise to blood cancers. Moreover, findings in mice with blood neoplasms suggest that a drug called tamoxifen, which targets estrogen receptors and is approved for treatment of breast cancer, may also be a valuable strategy for blocking the development of blood neoplasms in humans.
