I'm a 20 year old male. I have a friend that discovered a mass in one of his testicles. He says that it doesn't hurt, but his mom told him to see his doctor because it could be cancer. This scares me because I don't know if I could get cancer. Testicular cancer is the most prevalent type of cancer in men ages 15-34, which includes most college students.
Testicular cancer exhibits no early symptoms, so early detection is crucial.
First, get comfortable with your body. After all, it is yours. A testicular self exam is relatively easy and private. Perform the exam once every month. To help with consistency, pick a date for performing the exam that will be the same every month, the 10th for example.
