Fibroadenomas are often discovered incidentally during self-breast examinations or imaging methods such as ultrasound, as they typically do not cause pain.

The general characteristics and signs of fibroadenomas can be summarized as follows:
* Fibroadenoma masses are distinct, smooth, well-defined, and typically round or oval.
* They usually feel like a movable lump under the skin when touched.
* They have a firm or rubbery consistency.
* While generally painless, they can sometimes feel tender or even painful, especially just before menstrual periods.
* One or more fibroadenomas may be present in one or both breasts.
* Unlike cancerous lumps, fibroadenomas typically do not cause nipple discharge, swelling, redness, or skin irritation around the breast.
