Testicular cancer is the most common cancer in men in their 2nd and 3rd decades of life. It has higher than 90% survival rate amongst all patients. However, early diagnosis and appropriate treatment are key. The most common symptom is a testicular lump. Not all lumps are cancer, but an ultrasound and laboratory tests will help our diagnosis it properly. The initial treatment for testicular cancer is the removal of the testicle with the mass. Usually, patients can have a testicular prosthesis placed at the same time, so that cosmetically, the scrotum appears untouched. Based on the pathology findings from the surgery, more therapy may be needed including chemotherapy, radiation or more surgery.
