Powerful biomarker panel for the early detection of breast cancerIn the war on cancer, perhaps there is nothing more powerful in a physician's arsenal than early detection. Despite recent advances in early detection and therapy, breast cancer remains a common and significant health problem in the United States and worldwide. Approximately one in ten women will get breast cancer in their lifetime and more than half of women with late stage cancer (II and III) have no cure or effective therapeutic available.

Does it hurt?It is well known that pain is a highly subjective experience. We each have a pain threshold, but this can vary depending on distractions and mood. A paper in the International Journal of Behavioural and Healthcare Research offers a cautionary note on measuring perceived pain in research.
There are a number of chronic illnesses and injuries that have no well-defined symptoms other than pain, but because of the subjectivity in a patient's........Go to the Psychology news blog (Added on 1/11/2011 6:24:06 AM)
