About the symptom

Breast asymmetry occurs when one breast has a different size, volume, position, or form from the other. Breast asymmetry is normal, and almost every woman's breasts are not exactly the same on both sides. Poland's syndrome is a very rare condition where the chest muscles are missing or underdeveloped on one side and the breast is also much smaller. This can happen in women or men. In general, this is all normal. If asymmetry occurs rapidly and one breast becomes much smaller or larger over a short period of time this should be evaluated by a physician.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Difference in nipple heights or breat appearance

Possible causes

  • Breast cancer

    Breast cancer is a malignancy that arises in the breasts of men or women. It can arise from ducts or lobules. Patients either find a lump or have an abnormal mammogram. Risk factors include being female, having breasts, have a genetic predisposition (eg a gene you inherit from a parent), family history of breast or ovarian cancer, getting older, personal history of breast biopsies, dense breasts on mammography, or ovarian cancer, alcohol, and obesity. Protective factors include pregnancy, especially at a younger age, weight maintenance especially after menopause, and exercise.

  • Mastopathy

    A condition where a painful lump forms in the breast due to imbalances in female hormone levels, causing symptoms to occur before and during menstruation.
