Advanced breast cancer has increased slightly among young women, a 34-year analysis suggests. The disease is still uncommon among women younger than 40, and the small change has experts scratching their heads about possible reasons.
Not all patient drug trials published in even the most prestigious of medical journals can be taken as gospel, say researchers, who have found a high proportion of "spin and bias" in the reporting of results.
Women who work in certain manufacturing environments face an increased risk of breast cancer of nearly 50 per cent due to years of exposure to carcinogens and hormone-disrupting chemicals, a new landmark Canadian study shows.
An independent panel in Britain has found that for every life saved, roughly three other women were overdiagnosed, meaning they were unnecessarily treated for a cancer that would never have threatened their lives.
An experimental breast cancer treatment that directly targets disease cells appears to shrink tumours and improve survival rates, a new study says, and could one day lead to more effective treatment of other types of cancer with fewer side effects.
