Skin Type = American Academy of Dermatology Skin Types I–VI:

I. Pale white skin: Always burns easily; never tans (Celtic, Scandinavian, and infants)

II. White: Usually burns easily; tans minimally (Northern European)

III. White (average): Sometimes burns; tans gradually to light brown (Central European)

IV. Beige or lightly tanned: Burns minimally; always tans to moderately brown (Mediterranean, Asian)

V. Moderate brown or tanned: Rarely burns; tans well (South American, Indian, Native American)

VI. Dark brown or black: Never burns; deeply pigmented (African, African-American, Aborigine)

Location of Primary Tumor: Lt = Left; Rt = Right. C = Center; I = Inner; L = Lower; O = Outer; U = Upper.

Histological Types: IDC = Invasive ductal carcinoma; ILC = Intralobular carcinoma; IMPC = Invasive micro-papillary carcinoma.

Node Histology: − = No evidence of metastasis; m = Micrometastases < 1 mm; + = Metastases ≥ 1 mm.

Axillary Node Dissection: Pos = Number of positive lymph nodes identified; Tot = Total lymph nodes identified; n.d. = Not done.
