Fibroadenomas are benign (non-cancerous) tumors made up of glandular and fibrous tissue, commonly found in the breast. They are one of the most common types of breast lumps in women, especially in those under 30. Fibroadenomas typically feel smooth, firm, and rubbery, and can vary in size from very small to several centimeters in diameter. While they are generally painless, they can sometimes cause discomfort, particularly during hormonal fluctuations, such as around the menstrual cycle. The exact cause of fibroadenomas is not fully understood, but they are often linked to hormonal changes, which is why they are more common in younger women and tend to shrink after menopause.

In most cases, fibroadenomas do not require treatment unless they cause pain or grow significantly. Diagnosis is usually made through imaging tests such as mammograms or ultrasounds, and sometimes a biopsy is performed to confirm that the lump is benign. In cases where the fibroadenoma is large, growing, or causing discomfort, surgical removal may be considered. However, if the lump is stable and asymptomatic, regular monitoring with follow-up exams is typically recommended. While fibroadenomas are not linked to breast cancer, it is essential to monitor them for any changes over time, as a small percentage of women with fibroadenomas may develop other types of breast abnormalities.
