Surviving cancer may depend on where you live in the world: Report

Cancer survival rates differ depending on where you live, according to a report.

— -- Cancer remains one of the leading causes of death around the world.

A new study published by The Lancet Tuesday shows a tremendous amount of variability in five-year cancer survival rates between countries. Though the study shows cancer survival worldwide is increasing overall, the results shed light on the deep disparities that exist around the globe.

For this study, an international team of researchers reviewed more than 300 cancer registries from 71 countries. From this, it identified 37.5 million patients who had been diagnosed with one of 18 common cancer types, between 2000 and 2014.

Similarly, the five-year survival rate for pediatric brain cancer is 80 percent in Sweden and Denmark, but only 28.9 percent in Brazil.

Claudia Allemani, lead author and researcher for the Cancer Survival Group at the London School of Hygiene and Tropical Medicine, believes identification of these disparities is the exact reason to keep watching cancer survival trends and expanding the database.

“Continuous monitoring of global trends in cancer survival is crucial to assess the overall effectiveness of health systems worldwide and to help policymakers plan better strategies for cancer control,” Allemani said in a statement.

“Governments must recognize cancer registries as efficient public health instruments that produce a continuous stream of valuable information on both the impact of cancer prevention strategies and the effectiveness of health systems, and at very low cost,” she added.
