Increased Risk of Second Tumors Among Cancer Survivors in Switzerland

10.12.2024 – Cancer survivors face a heightened risk of developing second tumors, according to the first-ever national Health Report on Cancer, with major contributions from the Swiss Childhood Cancer Registry (ChCR), hosted at ISPM Bern.

The report, based on 30 years of cancer registry data, reveals that the risk of a second tumor is 13% higher for cancer survivors than for the general population. This risk varies depending on age at first diagnosis, treatment type, and the time elapsed since the initial cancer. Notably, childhood cancer survivors face a sixfold risk, while young adults have double the risk.

"These findings underline the importance of tailored follow-up care and preventive strategies for cancer survivors," says Prof. Dr. Claudia Kuehni, Head of the ChCR.

The report highlights the influence of smoking- and alcohol-related cancers and treatments on second tumor risk and calls for strengthened prevention and improved digital health systems to ensure comprehensive patient records.
