How do you know if you have testicular cancer?

If you think there is a lump on your testicle, it could be cancer. Testicular cancer grows slowly at times, and quickly at others. Some lesions are benign, meaning that they are bothersome, but won’t spread. Others are malignant and have potential for great harm. There are many examples of a person having a problem and not noticing it until they have an “event” like falling off of a bike. The best way to be sure is to visit your urologist. They will be able to examine it and see what it is all about. They might even order an ultrasound of your scrotum to see what it looks like inside and help make the decision easier. Hopefully it will turn out to be a cyst or fibrotic mass and not cancer at all.
