In the young men’s population, testicular cancer (TC) is characterized as one of the main causes of morbidity and mortality around the world. This cancer is mainly divided into germ cell and nongerm cell types and manifests different signs and symptoms, like bone pain, nausea, lower back pain, and anorexia.
