How breast tissue normally feels
During a breast self-exam, you'll feel tissues of varying consistency. Glandular tissue usually feels firm and slightly rope-like, bumpy or lumpy (nodular); it's primarily felt in the upper, outer region of your breast. Surrounding fat tissue is soft; it's often felt in the inner and lower portions of your breast. The contrast between these two types of tissue is often more pronounced just before your period due to hormonal influences on the breast.
Besides changes related to your menstrual cycle, breast tissue also changes as you age. In the majority of women, breast tissue becomes more fatty and less dense over time. You may find that your breast-related symptoms, such as tenderness or lumpiness, also differ over the course of your menstrual cycle and as you get older.

However, the cause of a breast lump or other change can't be determined based on a clinical breast exam alone - more testing will be needed.
