What is the STEED Study?
STEED stands for Servicemen’s Testicular tumor Environmental Endocrine Determinants Study. The purpose of the STEED Study is to determine what causes testicular cancer and why testicular cancer is the most common cancer among young men, including soldiers, sailors, airmen, and marines, in the United States. About 2,400 military servicemen and their mothers will be invited to participate in the STEED study.
