women are suffering from more and more pressure
With the development of society, women are suffering from more and more pressure from work and life. While some of them ignore the possible sickness, especially mammary cancer. We Perlong Medical are always caring for people’s health, also including the women. Our portfolio adds new mammography system. There are totally four models and the main difference is the tube head. Our customers can make the choice according to their request and financial status.
Mammography is the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast and is used as a diagnostic and a screening tool. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses and/or microcalcifications.
Like all X-rays, mammograms use doses of ionizing radiation to create images. Radiologists then analyze the images for any abnormal findings. It is normal to use lower-energy X-rays (typically Mo-K) than those used for radiography of bones. Ultrasound, ductography, positron emission mammography (PEM), and magnetic resonance imaging (MRI) are adjuncts to mammography. Ultrasound is typically used for further evaluation of masses found on mammography or palpable masses not seen on mammograms. Ductograms are still used in some institutions for evaluation of bloody nipple discharge when the mammogram is non-diagnostic. MRI can be useful for further evaluation of questionable findings as well as for screening pre-surgical evaluation in patients with known breast cancer to detect any additional lesions that might change the surgical approach, for instance from breast-conserving lumpectomy to mastectomy. New procedures, including breast tomosynthesis, may offer benefits in years to come.
For the average woman, the U.S. Preventive Services Task Force recommended (2009) mammography every two years in women between the ages of 50 and 74.[1] The Canadian Task Force on Preventive Health Care (2012) and the European Cancer Observatory (2011) recommends mammography every 2–3 years between 50 and 69.[2][3] These task force reports point out that in addition to unnecessary surgery and anxiety, the risks of more frequent mammograms include a small but significant increase in breast cancer induced by radiation.[4][5] The Cochrane Collaboration (2011) concluded that mammograms reduce mortality from breast cancer by an absolute amount of 0.05% or a relative amount of 15%, but also result in unnecessary surgery and anxiety, resulting in their view that it is not clear whether mammography screening does more good or harm.[6] They thus state that universal screening may not be reasonable.[7]
Mammography has a false-negative (missed cancer) rate of at least 10 percent. This is partly due to dense tissues obscuring the cancer and the fact that the appearance of cancer on mammograms has a large overlap with the appearance of normal tissues. A meta-analysis review of programs in countries with organized screening found 52% over-diagnosis.[7]
We have sold a few units to abroad including Asia, Africa and South America and the feedback is good. It is very easy to install and maintenance. We will also attach the user’s manual and CD. Hope we could be reliable supplier very soon.
