Cancer survivors and secondary cancer survival rates
This part of the study painted a grim picture. Cancer survivors who developed SMNs had a much lower overall survival rate than that experienced by members of the control group who developed cancer.
86% of the control group who developed cancer survived for five years after the diagnosis. However, the cancer survivors who developed SMNs only had a 65% survival rate over the same length of time. This was for the solid cancers.
The difference was much smaller for nonsolid tumors, which was more lethal to people who developed cancer for the first time but less lethal for those who fought the same type of cancer a second time. In this case it was 80% compared with 73%, which the researchers said was statistically insignificant.
