Breasts with more supportive tissue (dense breast tissue) are firmer and harder to the touch than are breasts with more fatty tissue (nondense breast tissue). A good balance results in soft, supple, yet firm and perky breasts.
Cancer is harder to detect and more likely to occur in
dense breasts.
Sounds weird when used to
compliment nice breasts unless referring to perkiness because that would
otherwise indicate a hard breast, similar to some augmented breasts.
