MRI improves breast cancer diagnosis

Women who have been diagnosed with breast cancer in one breast have a higher risk of contracting the disease in their opposite breast as well.

Patient adherence an essential factor for successful tuberculosis treatment

Nearly 2 million people die from tuberculosis each year, mainly in the poorest countries. The pathogen, Koch's bacillus, can pass easily by aerial infection from one individual to another. The spread of the disease, favoured by the Aids epidemic and the appearance of multi-resistant strains, has led WHO to make tuberculosis control one of the world's main health priorities.

Immune response to cancer stem cells may dictate cancer's course

Although stem cells hold incredible promise in the fight against certain diseases, in cancer they're anything but helpful. In fact, mounting evidence is showing that a tumor's growth and spread may depend on 'cancer stem cells,' which comprise only a very small subset of the tumor.

Medications plus lifestyle changes work as well as angioplasty to reduce deaths in stable heart-disease patients

Coronary revascularization with stenting or balloon angioplasty combined with optimal medical therapy is no more effective in preventing a heart attack, other major cardiovascular events or death in patients with stable heart disease, than optimal medical therapy alone, results of a new study conducted in 50 hospitals in the U.S. and Canada has shown.

New procedure to estimate reproductive potential of individual embryos

To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF.
