The investigators found that reproductive risk factors varied considerably by breast cancer subtype. Their analysis included 1,023 women with breast cancer whose cells express the estrogen and progesterone receptors (called luminal cancers), 39 women with HER2-overexpressing breast cancer, and 78 triple-negative cases (no expression of estrogen, progesterone, or HER2 receptors). The study also included 1,476 women without breast cancer. � They added that additional studies on the causes of breast cancer subtypes are needed to better understand the biology of the disease.

The study�s results suggest that there are distinct and separate hormonal risk factors associated with different subtypes of breast cancer. Women with what is referred to as "triple-negative" breast cancer are more likely than other women with breast cancer to experience a relapse, a new study by Canadian researchers shows. Despite having a high risk of early recurrence, the study indicates that triple-negative breast cancer patients who remain disease-free for eight years are unlikely to die of breast cancer and may be "cured" of their disease.
