Feeling a lump can be scary, but not all lumps are harmful. Fibroadenomas are smooth, rubbery, and move easily under the skin. They’re very common in women between 15–35 and are usually harmless. Cysts, on the other hand, are fluid-filled sacs that may feel tender or fluctuate with your menstrual cycle.

Concerning lumps tend to feel harder, irregular in shape, and fixed in one place. The only way to know for sure is through proper evaluation, usually a clinical exam followed by an ultrasound. Understanding these differences helps you approach changes with clarity instead of fear. Most lumps are benign, but every lump deserves attention.
