^{^a}

Includes nine cases of invasive ductal carcinoma (IDC), one of invasive mucinous carcinoma (IMuC), and one of metastatic breast cancer of unspecified type.

^{^b}

Includes one case where a recurrence of prior cancer was diagnosed six months after NIRS study; analysis of the NIRS data, placed her in the right-breast active cancer category.

^{^c}

Includes 15 cases of IDC, 1 of invasive mammary carcinoma (IMaC), and 1 of occult breast carcinoma presenting as an axillary lymph-node adenocarcinoma and right-breast hyperplasia.

^{^d}

Includes 10 cases of IDC, 1 of invasive lobular carcinoma (ILC), and one of IMaC.

^{^e}

Includes one equivocal case: subject had a right-breast lumpectomy two years prior to NIRS study, and subsequent radiological scans indicate a recurrence.

^{^f}

Includes four cases of IDC, one of IMaC and one of IMuC.
