Understand
Breast asymmetry is a difference in breast size, shape or nipple position; a small difference is very common.
Possible symptoms
The difference may show through clothing, make bra fitting difficult or cause distress, usually without pain.
Causes and associated factors
Different development, weight change, pregnancy, breastfeeding, ageing, trauma or previous treatment may explain it.
Diagnosis
Assessment reviews onset, symptoms, impact and expectations, examines the area and checks for a medical cause that should be treated first.
Tests
Tests are not routine; imaging, blood tests or specialist review are selected when a change is new, painful, asymmetrical or unusual.
Course of the condition
Asymmetry may change until development is complete and vary with weight, hormones and age.
Care options
Information, a fitted bra or external prosthesis may be enough; individual surgery is considered after development is stable and disease has been excluded.
When to consult
Seek assessment if the concern persists, affects function or strongly affects wellbeing, to discuss benefits, limits, alternatives and risks.
Urgent help
New or rapidly increasing asymmetry, especially with a lump, discharge, nipple retraction or skin change, needs prompt medical assessment.
Questions for your doctor
- Should a medical cause be investigated before any procedure?
- Which non-surgical options are suitable?
- What result is realistic and durable?
- Which risks, scars and follow-up should I expect?
- Which signs after a procedure require urgent care?
