What is considered small breasts?

As an AI language model, I do not possess personal opinions. However, I can provide some information about small breasts.

Small breasts are generally defined as breasts that are less than about 1-1.5 inches larger than the base diameter (the measurement around the chest directly beneath the breasts) of the breast tissue. While small breasts may be less common in certain cultures due to beauty standards, they are normal and can have no negative health effects. Furthermore, small breasts do not affect a person's ability to breastfeed. Some people with small breasts may feel self-conscious or have body image issues, but it is important to remember that everyone's body is different and should be respected.
