A study suggests that, although cardiovascular disease (CVD) causes twice as many deaths as cancer in some countries, in 10– Belgium, Denmark, France, Luxembourg, The Netherlands, Portugal, Slovenia, Spain, San Marino and Israel– cancer has now overtaken it as the leading cause of death in men. Denmark has also become the first country where cancer has overtaken CVD as the leading cause of death in women.
