What does a movable, painless lump in the breast typically indicate?

A movable, painless lump in the breast is most commonly a fibroadenoma, a benign (non-cancerous) breast growth made of glandular and connective tissue. Fibroadenomas typically feel smooth, rubbery, and shift easily under the skin when touched. They are especially common in women between the ages of 15 and 35, though they can occur at any age.

Key characteristics of a fibroadenoma:

• Painless and firm
• Well-defined, round or oval shape
• Moves freely under the skin
• Usually 1–3 cm in size
• Often found during self-exams

While fibroadenomas are not cancerous, any new breast lump should be evaluated to rule out other conditions, including cysts, infections, or, less commonly, breast cancer. Symptoms like rapid growth, skin changes, nipple discharge, or pain warrant prompt medical attention.
