Any chances it's anything but cancer?

Whoever can help me out with this question, I would be extremely grateful for your advice. I'm a 20 year-old male and about a year ago, I noticed a small, painless lump on what I have recently learned is my spermatic cord. Being young and just hoping that nothing bad could ever happen to me, I passed this off quickly and avoided thorough examination. I avoided the subject for a long time until this morning when I gone to the bathroom. I had pushed up my scrotum a little bit and noticed there were a few lumps. I did a little research and learned that, no, this isn't normal and it doesn't eventually just go away. I would say there are about 4-5 lumps, but only the one closest to the testicle seems to be at least a little firm. I should also mention that it's completely painless and while I don't experience unusual urgency to urinate, I've maintained a rule for awhile now to not drink a single gulp a couple hours before I go to bed, or else I must get up in the middle of the night for a trip to the restroom. While i know this is not normal, and I must go to the doctor, I am going to be on the other side of the country for the next week so I'm unable to go. I just need to hear about alternatives to cancer. What else could it be?

The only safe way to know is to have a scrotal ultrasound done.  You said one of the lumps was close to your testicle?  Do you think its attached?  Testicular cancer would be a firm lump attached directly to the testicle but if you have several lumps I would suggest having this checked soon.  Could be nothing but my opinion is to be safe.  You can try the urology forum there's a doctor that frequently answers questions.  I wish you all the best.
