What causes changes in breasts?
Changes in your breasts can be due to many factors. The most common are normal hormonal changes related to the monthly period, pregnancy or menopause and changes due to ageing. Other common causes of changes to the breast which are not of concern, include fluid filled sacs called cysts and solid tissue growths called fibroadenomas. Many women will experience some of these changes at some point in their lives. Only a small proportion of breast changes will be due to cancer.
