Imaging Characteristics of Breast Cancer in Women Under 40 Years of Age

Summary

To evaluate if there is any imaging characteristic of breast cancers in women younger than 40 years of age.

Description

In Western countries, breast cancer is the most commonly diagnosed cancer in women and breast cancer screening using mammography has reduced breast cancer mortality by 18-29%. In Taiwan, breast cancer is the second most common cancer in women and the Bureau of Health Promotion, Department of Health has started breast cancer screening using mammography in women between 50 and 69 years old since 2002, between 40 and 49 years old since early 2004. However, young women at 20 to 39 years of age have never been enrolled in the mass screening mammography program because of their relatively young age and mammographic findings of breast cancer in young women were seldom reported.Some authors found out that breast cancer in young women is more advanced and more often presents with a mass, has higher grade, more extensively proliferating and vessel invading disease when compared with those in older age groups. Most intraductal carcinomas (>80%) present as clustered microcalcifications on mammograms, and the sensitivity of mammography can be reduced in younger, denser breasts. Given these, mammography seems not to be a proper diagnostic tool for breast cancer women at a younger age. However, this presumption needs to be clarified since there are neither definite documented facts regarding breast cancer manifestation of young women on mammograms, nor documented sensitivity and false-negative rate of mammography in detecting of breast cancer among young women, at whom mammography is seldom used to be a diagnostic imaging tool. Our study is conducted to analyze the mammographic findings of breast cancers in young women between 20 and 39 years of age, regarding tumor size, location, major finding type, pathology type and grade. We will compare all of the above issues between younger age group and older age groups (40 to 49 and 50 to 69 years old).The breast ultrasound findings of the breast cancer among young women will be also compared with their corresponding mammographic findings, regarding the sensitivity, specificity, false-negative rate and accuracy.

Medical and Biotech [MESH] Definitions

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.
