Breast fibroadenomas (BFA) are benign (non-cancerous) breast tumors that are comprised of glandular and fibrous breast tissue. These lumps can occur alone, in groups, or as a complex of lumps together. Sometimes women feel these in the breast when doing regular self-breast exams, or they may be found during a routine mammogram. Some are small (less than an inch in size), and others are quite large (the size of a lemon or larger).
