Some people have soft breasts and some have hard breasts. The following conditions are relevant: women’s breasts are made up of fat and breast tissue. Before the menstrual period, some women’s hormone secretion increases and their breasts become relatively hard, and then gradually soften after the period. Middle-aged women with a lack of collagen in their breasts or sagging breasts may also experience softer breasts. Harder breasts may be considered to have mastocytosis, a disease that causes hard lumps in the breasts accompanied by pain, especially before menstruation. The hardness or softness of the breasts may be related to other conditions. If the breasts appear too hard or painful, it is best to go to the hospital for further examination.
