Fibrocystic breast changes happen when women develop fluid-filled cysts along with areas of fibrosis in one or both breasts. Fibrosis is a thickening of the breast tissue that you and your doctor can feel through the skin. It can be somewhat firm, ropy, or rubbery. Fibrosis also can happen by itself without any cysts forming.
Fibrocystic breast changes are common. Women with this noncancerous benign condition often have lumpy, nodular breasts and experience breast pain that varies throughout the menstrual cycle. Doctors don't know exactly what causes fibrocystic breast changes, but the condition is likely due to hormone changes during your menstrual cycle that affect breast tissue.
These changes are sometimes called fibrocystic changes , and used to be called fibrocystic disease. Areas of fibrosis feel rubbery, firm, or hard to the touch. They are often felt as a round, movable lump, which might also be tender to the touch. Cysts begin when fluid starts to build up inside the breast glands. These can be felt easily and can be as large as 1 or 2 inches across.
