Improved technology and health insurance are helping cancer patients in the US, Japan and France live longer than those in other parts of the world.
A study published in the Lancet Oncology this week, which considered 12 million patients, found that there was a decline in death rates for all cancer cases in the US.
The study had considered the most common cases of the disease and found the highest survival rates amongst breast and prostate cancer patients in America.
In Japan there was also a decline in the death rates of colon and rectal cancers in men and the same result was seen among women in France.
While technologies like computed tomography scanners play a significant role in diagnosis and treatment, survival rate among those with private health insurance was found to be highest.
In the UK patients in Northern Ireland, according to the study, outlived the rest of the country. But patients in Wales and elderly women were seen to have poor survival rates.
