University of Colorado Cancer Center researchers used data from 4,276 cases of male breast cancer and 718,587 cases of female breast cancer to show that the disease is treated differently in men than in women. Specifically, male breast cancer is treated with mastectomy more often than female breast cancer, and in cases in which...

A hybrid approach to treating coronary artery disease that involves a "hybrid procedure" combining a minimally invasive bypass surgery with percutaneous coronary intervention was found to be feasible and safe in a clinical trial. This is the first randomized study of the technique. These findings were presented today at the...

According to a new study of heart attack patients treated with percutaneous coronary intervention, free access to platelet function testing had only a modest impact on anti-clotting drug selection and dosing. Findings of the TRANSLATE-POPS trial were presented today at the 25th annual Transcatheter Cardiovascular Therapeutics...
