A large study published in the journal, Lancet, has revealed that cancer survival is increasing across the world, however, some countries are faring better than others.
The study called CONCORD-3 covered 71 nations and 18 types of cancer. From this, researchers identified 37.5 million patients who had been diagnosed with one of these cancers between 2000 and 2014.
The study revealed that cancer survival rates have continued to remain high even after 15 years in countries such as the US, Canada, Australia, Finland, New Zealand, Iceland, Sweden, and Norway. According to the researchers, these countries register a 90 percent survival rate for certain types of cancer.
However, the results tell a different story around the rest of the world. In India for example, the five-year cancer survival rate is 66.1 percent while the US is up 90.2 percent. Australia’s five-year colon cancer survival rate is 70 percent while in Russia it is less than 50 percent.
The study also found there was a gap in worldwide cancer survival rates for children. Five-year survival rates of the most common type of pediatric leukemia were found to be 90 percent greater in multiple countries, yet it is less than 60 percent in China, Mexico, and Ecuador. The five-year survival rate for pediatric brain cancer followed a similar pattern, with Sweden and Denmark registering an 80 percent survival rate while Brazil has 28.9 percent.
Women diagnosed with cancer in the US and Australia registered a 90 percent survival rate between 2010 and 2014. 16 European countries saw their rate improve to 85 percent while eastern European countries had improved an improved rate of 71 percent.
“Governments must recognize cancer registries as efficient public health instruments that produce a continuous stream of valuable information,” said lead author of the study and researcher for the Cancer Survival Group at the London School of Hygiene and Tropical Medicine, Claudia Allemani.
