Eventhough we often consider the environment on a global scale, cells in our body also have to contend with environmental factors. New studies from a team of scientists from the Research Institute of the MUHC and McGill University show that the environment surrounding breast cancer cells plays a crucial role in determining whether tumor cells grow and migrate or whether they fade away. Their study is the first to identify the genes...http://medicineworld.org/cancer/lead/4-2008/predicting-breast-cancer-patient-outcome.html Raloxifene reduces risk of invasive estrogen-receptor positive breast cancer- July 23, 2008 Women who took raloxifene were less likely to develop invasive estrogen-receptor (ER) positive breast cancer compared with women who did not, as per data from a randomized controlled trial published online June 10 in the Journal of the National Cancer Institute The drug did not reduce the risk of non-invasive cancer or invasive ER-negative cancers........http://medicineworld.org/cancer/lead/6-2008/raloxifene-breast-cancer.html Benign Lesions Needs 6-month Mammogram Follow Up- July 23, 2008 Radiologists can, with confidence, recommend a six-month follow-up diagnostic mammogram rather than an immediate biopsy for patients with probably non-malignant breast lesions, a new study emphasizes. The study observed that six-month short-interval follow-up examinations had an 83% sensitivity, which is similar to the sensitivity of other diagnostic mammograms, said Erin J. Aiello Bowles, MPH, lead author of the study from the Group Health Center for Health Studies. High sensitivity means...http://medicineworld.org/cancer/lead/5-2008/6-month-mammogram-follow-up.html Understanding Of Cell Behaviour In Breast Cancer- July 23, 2008 The invasion and spread of cancer cells to other parts of the body, known as metastasis, is a principal cause of death in patients diagnosed with breast cancer. Eventhough patients with early stage, small, breast tumours have an excellent short term prognosis, more than 15 to 20 per cent of them will eventually develop distant metastases, and die from the disease. Vascular invasion - through lymphatic and blood vessels - is the major route for cancer spreading to regional lymph nodes and to the.http://medicineworld.org/cancer/lead/6-2008/understanding-of-cell-behaviour-in-breast-canc... Adding ultrasound screening to mammography- July 23, 2008 Adding a screening ultrasound examination to routine mammography reveals more breast cancers than mammography alone, as per results of a major new clinical trial. The trial, however, also observed that adding an ultrasound exam also increases the rate of false positive findings and unnecessary biopsies........http://medicineworld.org/cancer/lead/5-2008/adding-ultrasound-screening-to-mammography.htm... Young women's breast cancers have more aggressive genes- July 23, 2008 Young women's breast cancers tend to be more aggressive and less responsive to therapy than the cancers that arise in older women, and scientists at the Duke Comprehensive Cancer Center and the Duke Institute for Genome Sciences and Policy may have discovered part of the reason why: young women's breast cancers share unique genomic traits that the cancers in older women do not exhibit........http://medicineworld.org/cancer/lead/7-2008/young-womens-breast-cancers.html Link between vitamin D status, breast cancer- July 23, 2008 Using newly available data on worldwide cancer incidence, scientists at the Moores Cancer Center at University of California, San Diego (UCSD) and the Department of Family and Preventive Medicine have shown a clear association between deficiency in exposure to sunlight, specifically ultraviolet B (UVB), and breast cancer........http://medicineworld.org/cancer/lead/5-2008/link-between-vitamin-d-status-breast-cancer.ht... Herceptin targets breast cancer stem cells- July 23, 2008 A gene that is overexpressed in 20 percent of breast cancers increases the number of cancer stem cells, the cells that fuel a tumor's growth and spread, as per a new study from the University of Michigan Comprehensive Cancer Center. The gene, HER2, causes cancer stem cells to multiply and spread, explaining why HER2 has been associated with a more aggressive type of breast cancer and to metastatic disease, in which the cancer has spread beyond the breast, the scientists say........http://medicineworld.org/cancer/lead/7-2008/herceptin-targets-breast-cancer-stem-cells.htm... Vitamin A pushes breast cancer to form blood vessel cells- July 23, 2008 Scientists at Georgetown University Medical Center have discovered that vitamin A, when applied to breast cancer cells, turns on genes that can push stem cells embedded in a tumor to morph into endothelial cells. These cells can then build blood vessels to link up to the body's blood supply, promoting further tumor growth........http://medicineworld.org/cancer/lead/7-2008/vitamin-a-pushes-breast-cancer.html Physical activity prevent breast cancer- July 23, 2008 Physically active women are 25 per cent less likely to get breast cancer, but certain groups are more likely to see these benefits than others, finds a review of research published online ahead of print in the British Journal of Sports Medicine. The type of activity undertaken, at what time in life and the womans body mass index (BMI) will determine how protective the activity is against the disease........http://medicineworld.org/cancer/lead/5-2008/physical-activity-prevent-breast-cancer.html |
