Breasts are made up of milk-producing lobes and ducts that carry milk from lobes to the nipple. Lobes and ducts are surrounded by supportive tissue, fat and skin.
Women’s breasts do not look exactly the same. It is common to see some variation between the two breasts. It is also common for breasts to change their shape slightly and the way they feel according to the time of the menstrual cycles and age of the woman. Therefore, it is very important for every woman to know her breasts and the way they feel by doing regular breast self-examination. Any changes (whatever trivial) should be reported immediately to the GP. Most breast changes are not cancer.
