The opposite is true: Triple-negative breast cancer is defined by absent expression of the estrogen receptor [er], Progesterone receptor [pr], and human epidermal growth factor receptor 2 (her2). These cancers tend to behave more aggressively (grow faster) than other types of breast cancer.

No: Most triple negative breast cancers tend to be fast growing and more agressive than those which have hormone receptor positive cancer cells. But it is difficult to predict exactly.
