MicroRNA as Markers in Testicular Cancer

This study is looking at whether tiny molecules called microRNAs found in the blood can be used as reliable markers to detect and monitor testicular cancer, potentially making diagnosis and follow-up easier and less invasive. **You may be eligible if:** - You have a suspected testicular cancer and are scheduled for surgery to remove the testicle - You have been diagnosed with testicular germ cell cancer - You are between 18 and 70 years old - You are able to understand the study information and give consent **You may NOT be eligible if:** - You have another cancer (other than testicular cancer) either currently or in the past - You have other medical or mental health conditions that would prevent you from participating in follow-up visits Talk to your doctor to see if this trial is right for you.
