Approach to a lump in the breast: a regional perspective.

The clinical presentation, investigation and treatment of women with breast lumps are greatly influenced by geographical factors. These impact disease patterns and their presentation (e.g. socioeconomic/educational status and cultural/religious beliefs) and the availability of specialist health care personnel and facilities. The differential diagnoses of a breast lump include breast cancer, benign solid and cystic lumps and inflammatory conditions. The likelihood of a diagnosis relates more to geographical area, age, ethnic origin, family history of breast cancer, presence of high-risk pathology, endemic infection, smoking, pregnancy and lactation history, puerperal care and health education. Investigations and treatments vary more according to the availability of expertise and facilities (e.g. combined diagnostic clinic staffed by breast surgeon and radiologist; breast radiologist to carry out image-guided diagnostic and therapeutic procedures). This article discusses the clinical assessment and investigation of breast lumps and possible treatments from an Asia Pacific perspective.
