Physical examination of the breasts is important both in the evaluation of a breast complaint and screening for asymptomatic breast pathology such as a breast mass. The examination involves inspection of the breasts to look for asymmetry or skin/nipple changes, as well as palpation of the breasts, nipples, and axilla. Coupled with medical history, the outcome of a breast examination can be normal, lead to a clinical diagnosis (e.g., infection), or require additional diagnostic evaluation (e.g., the evaluation of a palpable breast mass or skin/nipple changes).

The anatomy of the breast and axilla Axilla The axilla is a pyramid-shaped space located between the upper thorax and the arm. The axilla has a base, an apex, and 4 walls (anterior, medial, lateral, posterior). The base of the pyramid is made up of the axillary skin. The apex is the axillary inlet, located between the 1st rib, superior border of the scapula, and clavicle. Axilla and Brachial Plexus: Anatomy as well as the relationship Relationship A connection, association, or involvement between 2 or more parties. Clinician–Patient Relationship to the thorax should be reviewed before starting. Knowledge of the underlying tissue anatomy makes interpreting and describing the findings easier.
To preserve modesty, cover the individual with an extra gown/sheet and expose only the breast to be examined.
Describe findings accurately to allow the practitioner to monitor for changes and, when imaging is required, communicate findings to the radiologist.

The tumors are well-circumscribed, mobile, and unencapsulated, with a rubbery or firm consistency.

Menopause can only be diagnosed retrospectively, after 12 months without menstrual bleeding.

The epidermis is primarily composed of keratinocytes that undergo rapid turnover, while the dermis contains dense layers of connective tissue. Skin: Structure and Functions or underlying tissues|
