Hard lump on right testicle
About 3 years ago, i had a hard lump on my right testicle, after a while it was gone. 3 weeks ago i noticed a pea sized lump that feels very similar to the earlier one. I haven't seen a doctor as i'm a student and having some trouble with free time since the semester's ending. Thinking about seeing a doctor this Saturday. Does anyone have any idea what it could be? I'd like to be prepared when I see a doctor and know what to ask about. Any suggestions are appreciated, thank you.
