breast fibrosis
(brest fy-BROH-sis)
A benign (not cancer) condition in which thickened or fibrous (scar-like) tissue is found in the breast. The areas of fibrosis usually feel firm, rubbery, or hard under the skin. Breast fibrosis may occur along with other changes in the breast, including cysts, breast swelling or discomfort, and nipple discharge. These changes may come and go throughout the menstrual cycle and usually stop after menopause. Breast fibrosis can occur at any age but is most common in younger women. Having breast fibrosis does not increase the risk of breast cancer.
