This study aims to evaluate if a light based technique, called Transillumination Breast Spectroscopy (TIBS), can be used to construct a non-invasive breast cancer risk predictor which provides a better odds ratio than mammographic parenchymal density.
In a previous cross sectional study in a group of women without breast cancer and with varying degrees of parenchymal density patterns, a strong association was demonstrated between Transillumination Breast Spectroscopy (TIBS) and x-ray derived mammographic density. From this, we expect that TIBS should also provide a comparable odds ratio (4-6) as mammographic density for breast cancer risk shown in other independent epidemiological studies. It is possible that TIBS may provide complementary information and a higher odds ratio if compared to the incidence of breast cancer. In contrast to mammography derived parenchymal density pattern, no historical TIBS data is available for a retrospective analysis and hence a cross sectional study within a group of screened women is proposed. We hypothesize that TIBS provides physical information about the breast tissue which can be used to construct a breast cancer risk predictor with an odd ratio > 6.

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
