Breast cancer is the most common cancer in women and the second most common cause of cancer death in women in 
the U.S. Symptoms include a lump in the breast or underarm area, nipple pain, change in breast size or shape, an inverted nipple, nipple discharge, and breast skin changes. Treatment may involve chemotherapy, radiation therapy, biological therapy, hormone therapy, or surgery.
One of Breast Cancer Research Journals provided below described about the vast majority of breast cancer effect due to metastasis. Accordingly, when breast cancer is detected after it is known, or suspected, to have metastasized, treatment decisions are more complex and prognosis is less favourable. Then a complementary approach comes from a growing understanding of the basic biology of the metastatic process of breast cancer.
The researchers have been using experimental in vivo videomicroscopy (IVVM) procedures in order to understand the biological and molecular mechanisms of metastasis. They also developed quantitative procedures to measure formally the efficiency of specific steps in the metastatic process.
Ann F Chambers from London Regional Cancer Centre, London, Ontario, Canada and colleagues performed a quantitative experimental studies on the basic biology of metastatic inefficiency that may help in understanding the significance of these cells of tumours. They conclude that some steps in metastasis appear to be quite inefficient, and the ability to accomplish these steps seems to vary markedly between cancer cells of high versus low metastatic ability, as well as between different organs.
