Populærvitenskapelig sammendrag av avhandlingen/ Summary of the thesis

How does testicular cancer (TC) treatment influence the subsequent risk for a second TC, a second cancer other than TC and mortality?

Complete TC treatment details were retrieved for all men diagnosed with TC in Norway 1980-2009 (n=5724) and linked with the Cancer Registry of Norway and the Norwegian Cause of Death Registry.

Treatment with cisplatin-based chemotherapy reduced the second TC risk compared with surgery, with a further risk reduction for each additional cycle administered. Older age at first TC also reduced the risk. Compared with the general population, treatment with chemotherapy and/or radiotherapy was associated with an increased risk of a second cancer and of premature mortality. Additionally, increased second cancer risk was observed after treatment with surgery only. Young age at TC diagnosis was associated with the highest risk of second cancer or mortality compared with the general population.

This information is important for health personnel and TC survivors.
