During pregnancy my breasts have become lumpy and big. How do I even know if a lump is new? Should I still check?

An AskHer answer: what is known, what depends on you, and what only a clinician can decide.

Nobody asked this one. AskHer’s editorial team wrote the question to open the topic. It is not anyone’s submission, and nobody’s own words are in it.

The short explanation

Yes, it is still worth being aware of your breasts in pregnancy, but it is normal for them to feel fuller, heavier and lumpier as the milk glands grow. Many women find this makes it hard to tell what is new. Rather than a strict monthly routine, notice how your breasts usually feel and look, and mention anything that stands out from the rest of the breast or the other side. A lump that is clearly different, stays the same or grows over a couple of weeks, or comes with skin or nipple changes should be checked, even during pregnancy.

What depends on your situation

The parts of this that change from woman to woman. Uncertainty is stated, not hidden.

  • Breast changes in pregnancy include darker, larger areolas, visible veins, small bumps around the areola, and sometimes a yellowish fluid called colostrum leaking from both nipples later in pregnancy. These are expected.
  • Breast cancer in pregnancy is uncommon, but it can be missed because lumps are assumed to be part of pregnancy. If you are worried, your antenatal doctor can examine you, and an ultrasound is safe during pregnancy.
  • Bring up any breast concern at an antenatal visit. You do not need to wait for a separate appointment.

What this answer cannot determine

The boundary of online education. These need a clinician who can see you.

  • This cannot tell you whether a lump you feel is normal pregnancy change. An examination, and sometimes an ultrasound, can.

Questions for your clinician

Take these with you. You can add any of them to an appointment card.

  1. Are the changes in my breasts normal for pregnancy?
  2. Can you examine this area that feels different?
  3. Is an ultrasound safe now if it is needed?
  4. Which changes should I tell you about straight away?

When to seek help

Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.

Book an appointment soon

  • See a clinician within a week or two for a lump that feels different from the rest, or sooner if there is bloody discharge or skin change.

Raise it at a routine appointment

  • Mention any breast concern at your next antenatal visit. You can ask for a woman doctor for the examination, and you can bring someone you trust into the room with you.
