Cancer statistics worldwide indicate survival rates are improving, but poorer countries are seeing less improvement than wealthier ones, a new study shows.
Researchers analyzed data from 2000 to 2014 to assess five-year cancer survival rates among 37.5 million children and adults diagnosed with one of 18 common cancers. These patients were from 71 countries and territories.
After taking into account a number of factors, the investigators found that survival for most of the cancers included in the study has been consistently high over the last 15 years in the United States, Canada, Australia, New Zealand, Finland, Norway, Iceland and Sweden.
But poorer nations have seen fewer gains.
For example, among women diagnosed with breast cancer in the United States and Australia between 2010 and 2014, five-year survival hit 90 percent, compared to only 66 percent for women diagnosed in India.
