Scientists have discovered one of the reasons why bladder cancer is so much more prevalent in men than women: A molecular receptor or protein that is much more active in men than women plays a role in the development of the disease. The finding could open the door to new types of treatment with the disease.
Access to antiretroviral therapy for advanced HIV infection in low- and middle-income countries continued to grow throughout 2006, with more than 2 million people living with HIV/AIDS receiving treatment in December 2006, a 54% increase over the 1.3 million people on treatment one year earlier in these countries.
Investigators at St. Jude Children?s Research Hospital say they have found the best way for predicting when patients will need future surgery to repair hip joints that have deteriorated because of pediatric leukemia or lymphoma treatment.
College-age students who drink heavily may increase their risk for future heart disease, researchers reported at the American Heart Association’s 8th Annual Conference on Arteriosclerosis, Thrombosis and Vascular Biology.
A grief counseling program for families bereaved by suicide does not reduce grief or depression, but may help to prevent perceptions of blame among close relatives and spouses, finds a study published online today.
Researchers at the Massachusetts General Hospital (MGH) Cancer Center have identified a subgroup of hard-to-treat breast cancers that may be sensitive to the drug cisplatin, rarely used in the treatment of breast tumors.
A report of data from the National Cancer Institute?s Surveillance Epidemiology and End Results (SEER) database published in the New England Journal of Medicine, suggests that a decline in breast cancer incidence may be caused by a drop in hormone therapy use during the same time period.
Women who take hormone replacement therapy are more likely to be diagnosed with ovarian cancer and to die of the disease, according to a study published in the Lancet.
Colon cancer could join the growing list of stem cell-related cancers with the discovery of a population of highly tumorigenic primary human colon tumor cells, according to researchers from Biogen Idec.
Radiation therapy affects not only the cancer mass, but also the surrounding tissues, including the bone marrow. Signals from the cells in the bone marrow damaged by cancer radiotherapy could be involved in the development of secondary acute myeloma by drawing hematopoietic stem cells, the blood-producing cells of the bone marrow, from distant sites into the irradiated bone marrow, according to researchers from the Ontario Cancer Institute. Their findings suggest that local radiotherapy leads to leukemia, even though radiotherapy directly affects only a small fraction of the bone marrow.
