Does breast cancer cause a breast lump?

Breast Lump is a very common presentation of Breast Cancer, but a lump can also come from a benign breast condition. Feeling a lump does not identify its cause by itself; an examination and, when needed, imaging are used to clarify it.

A cancer-related lump may feel firm, persist over time, or be located in the breast or armpit. Benign causes can include cysts, fibroadenomas, hormonal breast changes, or inflammation. Texture and tenderness can offer clues, yet they cannot reliably diagnose the lump at home.

A clinician may ask when you first noticed it, whether it changes during your menstrual cycle, and whether there are skin or nipple changes. Assessment may include a breast examination, ultrasound, mammogram, or tissue sampling depending on your age, findings, and history.

Arrange an appointment for any new breast lump, especially one that remains after your next menstrual period or feels different from surrounding tissue. Note its location, how long it has been present, and any related changes. Avoid repeatedly pressing it, which can make the area sore and harder to assess.

Bring information about prior breast problems, operations, pregnancies, medicines, and family history. The clinician can explain which test is appropriate and whether monitoring, drainage, biopsy, or another step is needed.

Seek prompt medical assessment for a new or enlarging lump, a lump in the armpit, skin dimpling, nipple inversion, bloody discharge, or a breast that becomes red, swollen, and persistently painful. Seek urgent help if redness is rapidly spreading or you feel very unwell with fever.

What features of this lump are you assessing? Which examination or imaging test should come first? If the lump needs sampling, how is that done and when will I receive the result? What changes should make me return sooner?
