Data from the 1970s and 1980s show that people affected by cancer survived significantly longer in West Germany than cancer patients behind the Iron Curtain.

The group analyzed cancer survival rates in the years from 2002 to 2006. They found that 5-year survival rates for 20 out of 25 cancer types differed by less than three percent between East and West and may therefore be regarded as almost identical.
Only for cancers of the oral cavity, the esophagus and the gall bladder as well as for melanoma, cancer patients in former West German states had statistically significantly higher 5-year survival rates. On the other hand, people living in the former East German states had a slight survival advantage for leukemias.
"The fact that cancer survival rates have aligned in the former West and East German states demonstrates that the standardized health system has created comparable health chances for people in the East and in the West. The dramatic differences in cancer survival rates have almost entirely disappeared, even though economic conditions continue to be different," says Hermann Brenner. "However, it makes more sense now to compare socio-economic differences within individual regions than to think in those obsolete categories of East and West."
