For many years, researchers and doctors have studied different kinds of treatments to improve the survival of men with testicular cancer. However, recent research has shown that many years later, men who had testicular cancer appear to be at higher risk for developing heart disease (heart attack or heart failure), especially if they received chemotherapy. Since these studies were done many years after men received treatment, there was no way to know if other factors contributed to the health problems they experienced. This study is being done because it would be helpful to study heart function and cardiovascular disease risk factors of men who have been diagnosed with testicular cancer, before and after they receive chemotherapy treatment compared to men who receive treatment with surgery alone.
