Mayo Clinic measures psychological and social impacts of contralateral prophylactic mastectomies

Mayo Clinic researchers report that most women who have a contralateral (opposite to cancerous breast) prophylactic mastectomy (CPM) are satisfied and would elect this procedure again. Satisfaction with CPM was studied an average of 10 years after the procedure was done. The findings were published online Oct. 3 in the Journal of Clinical Oncology. more

Study reveals reason women are more sensitive to pain than men

For centuries, it has been generally believed women are the more sensitive gender. A new study says that, when it comes to pain, women are in fact more sensitive.

Heart attack death rates found higher in hospitals treating larger share of African Americans  

Ninety days after acute myocardial infarction (AMI) -- or heart attack -- death rates for African Americans and white patients were found to be significantly higher in hospitals that disproportionately serve African-American patients than in hospitals that serve mainly white patients, according to a major new study led by researchers at Dartmouth Medical School. The researchers suggest that quality of care, more than racial differences per se, determines AMI outcomes. more

Schizophrenia: Delusion without illusion 

Scientists have discovered that schizophrenia sufferers are not fooled by a visual illusion and are able to judge it more accurately than non-schizophrenic observers. The study by UCL (University College London) and King's College London suggests that in everyday life, schizophrenics take less account of visual context. If this is part of a more general failure to deal appropriately with context, it could explain why some sufferers might misattribute people's actions or feel persecuted. more

Cholesterol levels and use of lipid-lowering drugs are not associated with breast cancer risk

Cholesterol levels and use of statins or other lipid-lowering drugs are not associated with breast cancer risk, according to a study in the October 24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. more


Studies on the association between the use of statins and breast cancer have had conflicting results.
