That is: a possibility, but it is more likely to be something benign like an epididymal cyst or varicocele. The only way to be sure is to see your doctor. You will probably need an ultrasound.

Get exam: Should see your Dr or a Urologist for evaluation and likely initial imaging to help determine what the lump is and what to do next.
