"Ahead of World Cancer Day, the United Nations health agency [Friday] launched a survey showing that more than half of all countries are struggling to prevent cancer and to provide appropriate long-term treatment and care to avoid human suffering and protect countries' social and economic development," the U.N. News Centre reports (2/1). "This means, currently many of these countries do not have a functional cancer control plan that includes prevention, early detection, treatment and care," according to a WHO press release.
