Tanner Staging of Breast and Pubic Hair development

This is a 5-stage system proposed by Marshall and Tanner in 1969 for grading female breast and pubic hair development.

Tanner staging of Breast Development

  1. Elevation of papilla only (pre-pubertal breast)
  2. Breast budding
  3. Enlargement of breast without areola separation/elevation
  4. Formation of secondary mound by areola
  5. Mature breast: areola regresses to form single contour of breast, only papilla remains projected.
