What usually causes a breast lump?

Most breast lumps are benign (non-cancerous). Common causes include:

  • Fibroadenomas (common, especially in younger women)
  • Cysts (fluid-filled sacs)
  • Normal changes in breast tissue linked to the menstrual cycle

A smaller number of lumps need further evaluation to rule out something more serious — this is exactly why testing matters rather than trying to guess based on how a lump feels.

Get any new lump checked See Dr. Chandak promptly for any new lump, especially one that feels hard, irregular in shape, doesn't move under the skin, or comes with skin dimpling, nipple retraction, or rapid growth. Even without these features, any new lump deserves a proper check.

What to expect at the clinic

Dr. Chandak will typically start with a clinical exam, followed by mammography and/or sono-mammography depending on your age and the nature of the lump. If needed, FNAC or a biopsy can confirm exactly what the lump is. If you've also noticed a lump in the armpit, see our Axillary Lump & Pain page for more on that specifically.

Frequently asked questions

No. Most breast lumps are benign. But only proper testing can confirm this with certainty, which is why every new lump should be checked.

Promptly — don't wait to see if it goes away on its own. Early evaluation gives the most options either way.

Usually a clinical exam followed by an ultrasound and/or mammogram. If something needs a closer look, FNAC or biopsy may follow.
