Follow-up of about 11 years of participants in the Women's Health Initiative finds that among postmenopausal women, use of estrogen plus progestin is associated with an increased incidence of breast cancers that are more advanced, and with a higher risk of deaths attributable to breast cancer, according to a study in the October 20 issue of JAMA. In the Women's Health Initiative (WHI) randomized, placebo-controlled trial of estrogen plus progestin, after an average intervention time of 5.6...

Researchers at the University of Illinois at Chicago College of Medicine have found how gene expression that may contribute to drug resistance is ramped up in unusual types of breast tumors. Their findings may offer new therapy targets. The study is published in the Oct. 8 issue of the Journal of Biological Chemistry, where it is designated a paper of the week. Approximately 70 percent of breast cancers express the estrogen receptor. These "ER-positive" tumors usually respond to...

New study in the Journal of the American College of Surgeons finds US Preventative Services Task Force mammography recommendations could hinder early detection CHICAGO -- New research findings published in the March issue of the Journal of the American College of Surgeons indicate that some breast cancers continue to be detected as a palpable lump rather than being found through mammographic screening. Patients who presented with palpable tumors "“ those detected as a result of breast...

A newly identified cancer biomarker could define a new subtype of breast cancer as well as offer a potential way to treat it, say researchers at Washington University School of Medicine in St. Louis. Their findings will be published in the March 1 online early edition issue of the Proceedings of the National Academy of Sciences. The research could further refine what recent breast cancer research has concluded: that breast cancer is not one disease, but many. So far, research has firmly...

Researchers at Dana-Farber Cancer Institute have discovered a gene activity signature that predicts a high risk of cancer recurrence in certain breast tumors that have been treated with commonly used chemotherapy drugs. Despite their resistance to drugs of the anthracycline class, the breast cancers bearing this gene signature will probably still be vulnerable to other types of chemotherapy agents, say scientists in a letter to be published in Nature Medicine on its Web site and later in a...

Genome rearrangements in 24 breast cancers The first detailed search of breast cancer genomes to uncover genomic rearrangements is published today. The team characterized the ways in which the human genome is broken and put back together in 24 cases of breast cancer. Rearrangements involve reshuffling and reorganization of the genome and include deletions, duplications and novel juxtaposition of DNA sequences. The study shows that breast cancer samples can differ greatly in the extent to...

Gene overexpressed in up to 20 percent of breast cancers responds to blood pressure drug in lab, U-M researchers report Researchers have identified a gene that is overexpressed in up to 20 percent of breast cancers and that could be blocked in the lab by a currently available blood pressure drug, according to a new study from the University of Michigan Comprehensive Cancer Center.The gene, called AGTR1, caused normal breast cells to behave like cancer cells. This behavior was reversed by...

WASHINGTON, March 12 /PRNewswire-USNewswire/ -- The U.S. Agency for International Development (USAID) is launching a unique partnership to reduce illnesses and deaths caused by cervical and breast cancers in the country of Georgia. The program, called "Survive" includes numerous USAID partners, including the U.S. Embassy in Georgia, the JSI Research and Training Institute, the Susan G. Komen Foundation, the Georgian Pharmaceutical Company, International Women's Association, the Georgian...

Research suggests that lifestyle changes and screening have shifted the type of breast cancers women are diagnosed with over the past couple of decades.It is now considered that women will more likely have hormone-dependent, slow-growing tumors, a comparison of tissue samples from the 1980s and 1990s shows.The British Journal of Cancer reported, that Scottish researchers also found improved survival over time. Over 40,000 women are diagnosed with breast cancer in the U.K. annually, and almost...

U.S. and Norwegian researchers say they hope their findings prompt a debate on whether breast cancer tumors ever go away on their own without treatment. In their article published Tuesday in the Archives of Internal Medicine, researchers said one type of cancer -- a rare childhood tumor -- found through screening sometimes spontaneously disappears and they want to learn whether the same phenomenon could happen with breast cancers found in mammograms, USA Today reported. The authors admit...
