Breast cancer is defined as out of control growth of cells in the breast which have the ability to form a tumor or lump. These lumps or tumors in the breast are easily detectable through an X-ray. Breast cancer can form in the duct, nipple, glands, or other tissues. The most common types of breast cancer are invasive lobular carcinoma, invasive ductal carcinoma, ductal carcinoma in situ, triple negative breast cancer, metastatic breast cancer, and less common being lymphomas or sarcomas and inflammatory breast cancer.

Breast cancer is one of the most common cancers among woman globally and a major cause of mortality. Therefore, early detection is needed for these diseases. Breast cancer is more prevalent in the industrialized countries due to modernized lifestyle; however, the rate of incidence is expected to rise in developing countries.
According to the WHO, in 2012, round 1.7 million new cases of breast cancer were diagnosed globally. According to the American Cancer Society, breast cancer accounts for 1 in 8 cancers diagnosed in women in the U.S. Symptoms of breast cancer may or may not appear in women. Hence, regular screening is necessary to prevent the malignancy. Breast cancer screening is a regular examination to detect breast cancer. Early detection could ensure timely treatment of patients, thereby reducing the mortality rate. Breast cancer screening generally involves mammography, MRI scan, or ultrasound. Mammography is considered to be the best screening test for the detection of breast cancer.
A rise in the standard of living and educational opportunities for women had resulted in late first pregnancy with limited lactation period indirectly leading to fluctuating hormone levels and high risk of breast cancer. Probability of breast cancer increases with age. Hence, rise in geriatric population is a major factor for increase in incidence of breast cancer.
Rise in incidence of breast cancer, growing awareness about breast cancer screening tests, government initiatives for breast cancer screening programs, technical advancements in breast imaging technologies, implementation of national level programs by the government for early diagnosis are the major factors driving the market.
Based on diagnostic test type, the global breast cancer screening tests market can be segmented into blood marker tests, imaging test, genetic test, and immunohistochemistry test. Imaging test is the most commonly used test for the screening of breast cancer. The segment can be further divided into mammography, MRI screening test, molecular breast imaging test, PET scan, and ultrasound. Mammography is the most common test used for the detection of breast cancer. Genetic test can be sub-segmented into fluorescence in situ hybridization and HER gene test. In most developed countries, mammography is included in the breast screening program making it the most popular breast cancer screening test.
In terms of end-user, the global breast screening tests market can be segmented into hospitals, diagnostic centers, cancer institutes, and research laboratories. National breast cancer screening awareness programs and awareness about genetic transfer of breast cancer boost the growth of the diagnostic centers segment.
